Flatten PDF Without Watermark
Flatten PDF with no watermark — flattened PDF comes out clean, with no logo, stamp, or "created with" banner added to the page. Watermarks on free tools are a pressure tactic: process your file, then pay to remove the branding before you can actually use it. ContinuePDF never adds one, so the file you download is ready for clients, print, and professional use as-is.

What you can do with Flatten PDF
Flattening merges a PDF's interactive layers — form fields, annotations, stamps, and comments — into the page itself, so the document looks the same everywhere and its contents can no longer be changed or removed.
Lock a completed form
Flatten a filled-in form so the entered values become permanent and cannot be edited or cleared.
Preserve annotations
Bake highlights and comments into the page so they do not disappear in another viewer.
Fix rendering differences
Ensure a form looks identical across readers by turning fields into static content.
Prepare a final version
Produce a stable file for printing or archiving where nothing can shift or be interacted with.
Truly watermark-free Flatten PDF
Many free PDF tools quietly print their brand across your output, then offer a "premium" plan to remove it. For anything you plan to send to a client, submit officially, or print, that watermark makes the free version useless — which is exactly the point of adding it.
ContinuePDF's Flatten PDF produces the same clean file for everyone. There is no free-versus-paid difference in the output, no hidden watermark layer, and no toggle you have to find. Your PDF is processed and flattened PDF is returned exactly as it should look — professional and unbranded.

Pro tip
Flatten only after everything is final — once fields and annotations are merged into the page, you cannot edit them again. Keep an unflattened copy if you might need to change the form data later.
Frequently asked questions
Can I still edit the form after flattening?
No. Flattening makes fields and annotations part of the page, so entered data becomes permanent. Save a separate copy first if you may need to edit it later.
Does flattening change how the document looks?
It should not — the visible content stays the same. What changes is that interactive elements become fixed, so the file displays and prints consistently everywhere.
Does ContinuePDF add a watermark to flattened PDF?
No. Flatten PDF never adds a watermark, logo, or branding to your output. The file downloads clean and is ready for professional use — there is no paid step required to remove branding.
Is the watermark-free version really free?
Yes. Unlike tools that watermark the free output and charge to remove it, ContinuePDF gives everyone the same clean, unbranded result at no cost.
Is ContinuePDF free to use?
Yes. ContinuePDF and all of its tools, including Flatten PDF, are free with no signup required. Because documents are processed in your browser rather than on our servers, we can offer the full feature set at no cost.
