Flatten PDF forms and annotations

Fields and comments become part of the page

Up to 200 MB at a time. On a phone, large documents take longer and need more memory.

You can pick several PDFs. Each gets its own result, and you can also download them all as one ZIP.

Pages are turned into images of up to 144 dpi (4 megapixels per page at most). Searchable text, links, bookmarks and fillable forms don't carry over. Check the preview first.

Keep the original. Editing a PDF can invalidate a digital signature, and special features, forms and bookmarks may not carry over to the new file.

Your file stays on your device. No sign-up, no limits.

Flattening a PDF turns a filled-in form and its visible comments into a copy whose pages are images. The values look the same for whoever receives it and can't be edited by mistake. Pop-up comments that don't show on the page are left out. Text is no longer searchable, so keep the original with its fields.

How it works

To flatten several forms at once, choose all the files together. Each gets its own flattened copy.

Press “Save PDF” and check the preview before you download.

Worked example

You filled in a job application as a PDF form, but on some computers the fields show up blank. Make a flattened copy, check your name, date and figures in the preview, and send that one.

Questions people ask

Does a digital signature survive?

No. It's a new document without the cryptographic proof of the signature, so keep the signed original.

What happens to comments?

Visible notes become part of the page image. Hidden pop-up comment text and attachments don't make it into the copy.

Can I edit the fields again later?

Not in this copy. Open the original PDF to keep filling it in.

Why flatten a PDF before sending it?

So the form looks the same in every reader and nobody can change the values, accidentally or otherwise.
