A better way to protect and sell your PDF eBook files from WordPress

WP PDF Stamper Plugin – Stamp Your eBooks with Customer Details to Discourage File Sharing

1. Are you selling eBooks or PDF files from your WordPress site?

2. Are you concerned that one of your customers might upload your eBook on a file sharing site and you will lose sales?

3. Would you like to automatically stamp the header or footer of your PDF files with the customer’s personal details (example: name, email, address) upon purchase to discourage sharing?

If you have answered “yes” to all of the above then the WP PDF Stamper plugin will be the perfect solution for your site.

Plugin Summary

The WP PDF Stamper plugin allows you to dynamically stamp a PDF file with the customer’s details (example: name, email, address etc.) upon purchase. The PDF stamper then sends the stamped copy of the PDF file (your eBook) to the customer via email. If you are wondering why it is important to stamp the PDF eBook before giving it to your customer then this page is for you.

Additionally, you can password protect the stamped PDF files with the customer’s email address and encrypt the PDF files to prevent users from being able to copy, modify or print the content of the file.

    The PDF Stamper doesn’t have the ability to check the authentication system of a plugin as different membership plugins will have different methods of authentication. The PDF Stamper has API that can be used to stamp a PDF file from a different plugin or script. So you can develop a separate plugin or script that checks the authentication of the system that you are using and then uses the PDF Stamper’s API to stamp the PDF file then deliver the stamped copy of the file. You essentially use PDF stamper as the engine to stamp the PDF file:

    I already have implemented a different membership plugin (s2Member). I provide digital content of my magazine online to the paid subscribers.

    I like to add a “download PDF” option for offline viewing of my magazine to my paid subscribers. So, I like this plugin to stamp an issue of the magazine PDF that is already on the server with the subscriber’s information for offline downloading.

    So, can PDF Stamper plugin simply verify that the user is logged in and a paid subscriber and just stamp the requested PDF, or does it require the payment process with every PDF stamping? If it doesn’t support this, do you think it’s easy for an intermediate PHP developer to modify your code to implement this feature?

    1. Yes you can use only the email password protection feature with the customer’s email address.

    2. You can only specify what page to start on.
    Example: You can have the stamping start of the 10th page of the PDF. It will then stamp the 10th page till the end of the PDF file.

    3. Please see the following forum post as I believe this is what you are looking for: http://www.tipsandtricks-hq.com/forum/topic/using-pdf-stamper-with-emember-or-even-wishlist-memer
    Note you will need to use the eStore, eMember and PDF Stamper for the above option.

  4. Nena says:

    Hi Iviy,


    1. Is there a way to use ONLY the Password-protected feature with the customer´s email?

    2. Is there a way to have the footer ONLY in the first and last page?

    3. Is there a way to use the plugin in a membership site page, where customers can download the PDF? I mean: I have a Membership site where all customers can access different pages of content and they can download pdf´s. I would like to use this in that situation, but don´t know how the plugin could then identify what customer is downloading… Through IP maybe?

    This WordPress PDF Stamper just might what I need!

    I just started a new WordPress Blog for services and information in my home town and was trying to decide (or find) the best solution to protect the PDF’s I plan to have available for my local paying clients. The info that I will be selling is super valuable… so the concern that it might get out too easily is a big one! Awesome! 😉

    @John, You can specify multiple files per product in eStore. Read the help text below the “Digital Product URL” field and it will get clear to you. Essentially you just specify your file URLs separated by comma (PDF stamper will stamp all those PDF files)

  7. John says:

    I have to offer a zipped products (multi files) because eStore will only accept one file per product. Will the Stamper stamp each PDF in that zip file. If not, how do I use stamper to stamp multiple pdfs in my products and use eStore too?

    I have eStore already and I hope there is an easy solution

  8. Giro says:

    Nice Plugin, great! I will buy it as soon as i need it. Im not finished with my ebook right now but time will fix this.

    Thanks for coding this!

  9. Jake Renneah says:

    Thank you for all the great resources, we always build on wordpress themes…nothing else gives you the ability to create customization for clients, gives you the flexibility in web design, and allows you to make the sites just about assearch engine friendly as we can. They’ve always had a probable protecting our PDFs so thank you

  10. admin says:

    @French Marketer, my reply from the thread just above your comment should answer your question.

  11. The French Marketer says:

    I’m using a custom shopping cart solution.

    How would I get the plugin to stamp files for my customers ?
    Do I create a new WordPress blog, and then send my customers to a “register” page ?
    Then where will they get to download the stamped file ?

    Thanks in advance for your answers,

  12. admin says:

    @MacMyDay, The PDF Stamper has an API that can be used to integrate with any shopping cart plugin. The integration needs to be done by the shopping cart developer. We are always open to help with the integration but the developer has to be interested in the first place.

    The documentation site has more details on the Integration API

  13. MacMyDay says:

    Can this pdf stamper be used with other commerce plugins such as Shopp, eShop or Cart66?

  14. admin says:

    The way manual checkout works is that you send the product manually after your receive the money. You can’t have the same level of automation like you get with PayPal when using the manual checkout. This is because the plugin has no way of verifying that the customer gave you the money when you use manual checkout process. So when using manual checkout you can’t have the same flow like the instant payment options (example: PayPal).

    You will have to manually stamp the file (using the manual stamping menu of the plugin) after you receive the money and then send it to the customer.

  15. Thomas says:

    Yes, I saw this option, but following the explanation: ”
    Usually the product download links are given to the customer after a confirmed payment. In the event of manual payment the plugin has no way of verifying the payment so it is preferred that you manually give out the links after you receive the payment. Checking this option will force the plugin to send out download links in the manual checkout email that the customer receives after checkout.”
    If I understand this correct, the customer will receive without any payment just after checkout. If I want to do this like you also prefer, to send the Link after receiving the payment, how can I send automatically downloadlink to the stamped and password protechted (with PW = Mailaddress) Files to the Customers.

    Sorry, my english is not well practised…

    Thanks for you help

  16. admin says:

    @Thomas, eStore’s manual gateway has the following option:

    Send Product Download Links in the Email

    If you check that option it will automatically stamp the PDF file and send it to the customer when he submits the manual checkout form.

  17. Thomas says:

    Yes, exactly. Sorry for my bad explanation, I am from Germany.

  18. admin says:

    @Thomas, what do you mean by the 2nd payment gateway? Is it the “Manual Payment” option of eStore?

  19. Thomas says:

    I use PDF Stamper and WP eStore. I offer a second payment gateway, in this case I have to wait for the payment before the customer can receive the stamped ebook via a download link. So I disabled the option that the customer receive the download link. Do I have to stamp manually after I received the money? Ho can I do this automatically? Otherwise I have to stamp, save this PDF and send the PDF as an attachmend to the customer. Is there any possibility to get this easier done? Thanks for you help.

  20. Ivy says:

    Hi Gabe, The following post will explain which text can be stamped by the PDF Stamper:

    See the section called: Footer Text Layout Settings

  21. Gabe says:

    Can Pdf stamper stamp date of purchase or does it already do this automatically because that would be great if it did?

  22. Ivy says:

    Hi, Yes it works with the current version of WordPress and PayPal the instructions are the same.

  23. Farbod says:

    I am just about to launch my site for my ebook, and I was wondering if the stamper works with WordPress 3.1.3, since the instruction videos seem to be for older versions of WordPress and PayPal? And so if it does work with current versions, how I do get the instruction videos for them? Thank you for your help and time.

  24. admin says:

    Hi Karin, the answer will vary depending on what kind of integration you have in place. I am going to make a guess here… I am guessing you are using the PDF stamper with Plain PayPal button. If my guess is correct then please open the “wp-pdf-stamper/api/ipn_customization_config.php” file and you will be able to customize the email that gets sent out to your customer including the “From Email Address”.

  25. Karin says:

    Hi there, great application! Just wanted to know how to change the email that includes the download link? I would like it to be FROM my business instead of WordPress. And I would also like to modify the actual email, so I can inform customers to use their email address as the password in order to open the link (as I have selected this security option in the settings, but it is not mentioned in the email text). Can you please help me? Thanks a lot!

  26. Joe Lavery says:

    I just got to say that you have developed an awesome plugin here! I’ve been looking for a reliable and affordable software like this for years.

    Just bought an hour ago and I’m already rocking and rolling… this is gonna be awesome!!! Thanks so much dude!

  27. Jane says:

    Perfect! I was just thinking about how to help my mom sell her book on crochet and recipes. This plugin will definitely be useful.

  28. admin says:

    @Nick, The PDF stamper does not do this but it won’t hard to add. All it needs to do is look up the details of the currently logged in user’s data and stamp the PDF file with those data.

    A WordPress shortcode that lets a logged in user download a stamped copy of a PDF file will do.

  29. Nick says:

    Hi guys

    Can you just clarify, if registered users download a PDF from the site (but don’t complete a transaction, ie pay anything) it can still stamp the PDF with their details

    I’m not talking about going through Aweber as another user has mentioned or just stamping it with some generic text but actually personalising the PDF with a name / email watermark through WordPress only

    Many thanks

  30. admin says:

    @Sonia, You can if you are using eStore’s squeeze form:

    The squeeze form created by eStore can sign up the customer to AWeber and then send them a stamped copy of the PDF file to their email address.

  31. Sonia says:

    I’d like to get people to sign up on my website to my mailing list via Aweber and then take them to a page on my site where they can download a stamped pdf.

    Can this be done with WP pdf stamper? Thanks.

  32. Jay says:

    Wow awesome plugin guys, can it stamp PDF’s without a transaction taking place?

    EG: A visitor comes and opts in to get my PDF and I want it to be stamped with his personalised info same as before just without them having to make a purchase.


  33. Melinda | SuperWAHM says:

    All fixed. Thanks so much for your help and great service Ivy!

  34. admin says:

    @Melinda, I am guessing you are using eStore for the packaged product option? If you are then yes PDF stamper will stamp all the PDF files in a package but since you have a mixture of PDF files and zip files it may be getting confused. Can you please create another test package product with only the PDF files then test it to see how that works?

  35. Melinda | SuperWAHM says:

    I’ve got a product with a multiple file download, 3 are zip files and 3 are pdf files. The PDF Stamper doesn’t seem to be working when there are multiple files – it’s working fine when it’s only one file.

    Is there a way to set it up so it will stamp the pdf files even in a bundled product?

  36. Ivy says:

    Hi D.K., The original PDF will need to be unsecured for stamping. With that said you can set different security options in the stamper that will be added to the stamped PDF file.

    No Printing
    Password protection
    No Copying
    No Modification

    Let me know if you have anymore questions,

  37. D.K. says:

    Can the PDF be secured so that it can only be printed?

    That is, no content copying or page extraction?

  38. Ivy says:

    Hi, All of our plugins work with the latest version of WordPress.

  39. Luke Richardson says:


    Does this work with wordpress 3.1?

    Does it work with google checkout and paypal?

  40. Ivy says:

    Hi Jared, Yes you can have different size PDF pages and landscape.

  41. Jared Zichek says:

    Does this plugin work with PDF files containing pages of various sizes? I want to sell a PDF with regular letter size (8.5″ x 11″) and legal size pages (8.5″ x 14″), the latter in landscape format. Thank you in advance for your response.
