- How we protect your files
To flatten a PDF, upload it and download the flattened copy: filled form fields, comments and stamps are merged into the page itself, so viewers see a fixed document instead of editable boxes. Use it before sharing final contracts or graded forms.
How it works

Add your PDF

What you see is what everyone gets — nothing can be moved, edited or hidden.
No more accidental edits
Filled form values can't be changed after flattening — ideal before sending contracts.
Prints exactly right
Annotations that printers sometimes skip become page content that always prints.
Compatible everywhere
Flattened files display identically even in viewers that handle annotations poorly.
Frequently asked questions
What exactly gets flattened?
Form fields, highlights, notes, stamps, drawings and signature appearances are merged into the page content.
Can flattening be undone?
No — that is the point. Keep your original file if you need to edit the annotations later.
Does it change how the PDF looks?
No. The visible result is identical; only the editable layers are removed.
Is it free?
Yes, free without an account; files are private and deleted after 60 minutes.
Why flatten a PDF before sending it?
Flattening stops recipients from clicking into form fields or moving annotations, and fixes printers that skip unflattened form text. The content becomes part of the page.
