Flatten a PDF

Drop a PDF that has fillable fields, filled in or not, and flatten turns whatever is in those fields into regular, fixed page content: no more editable boxes, no more checkbox to click, just the final look of the page.

How it works

Drop your PDF

Any PDF, with or without form fields.

Check the field count shown

Lets you confirm the file actually has fields to flatten.

Flatten and download

Fields turn into fixed page content, keeping their current values.

Make a filled-in PDF form final

A fillable PDF stays editable forever: anyone who opens it can change the text boxes, tick or untick checkboxes, pick a different option. That's exactly what you want while a form is being filled in, and exactly what you don't want once it's done and ready to send, print or archive. Flattening bakes the current value of every field directly into the page, the same way text looks once you print a page and it stops being an interactive form.

How it works

Drop your PDF. If it has fillable fields, you'll see how many were found; whatever value each one currently holds —text typed in, a checkbox ticked, an option selected— is what gets locked in. Flatten and download to get a PDF where that content is now part of the fixed page, not a field.

What this is good for

A flattened PDF looks and prints identically everywhere, since there's no form renderer involved anymore, and its values can't be accidentally changed by whoever opens it next. It's the natural last step after filling out a form, whether you used our fill a PDF form tool or filled it in a PDF reader.

A signature stays put too

If you used our sign a PDF tool to place a signature image on the page, that image is regular page content already, not a form field, so it's untouched by flattening either way. What flattening removes is the ability to click into a text box, tick a checkbox, or pick a different dropdown option — the interactive layer, not the visible content.

Privacy

Your PDF is flattened entirely in your browser. Nothing is uploaded, which matters for forms that usually carry personal or sensitive information.

Frequently asked questions

What does flattening a PDF form mean?
It turns every fillable field into fixed page content showing its current value, so the field can no longer be edited or clicked.
Does flattening change what the form looks like?
No, the current values stay exactly as they were; only their editability changes.
What if my PDF has no fillable fields?
It's saved as is; there's nothing to flatten.
Can I flatten a PDF I haven't filled in yet?
Yes, but empty fields will just become empty, fixed space — fill it in first if you want the answers to show.
Is my PDF uploaded anywhere?
No. Everything happens entirely in your browser.
Can I undo flattening afterwards?
No, once fields become fixed page content there's no way to get the editable fields back. Keep a copy of the original if you might need to change it later.
