About this tool
Fillable forms store answers in separate fields. Some viewers don't display them, which is why a form you filled can arrive blank. Flattening bakes the answers into the page.
Looks the same everywhere
Fixes forms that appear empty in some phone or email previews.
Prevents edits
Answers become part of the page instead of editable fields.
Lossless
Pages aren't rasterized, so text stays sharp.
Flatten PDF FAQ
Can I edit the form after flattening?
No, that's the point. Keep the unflattened version if you may need to change answers later.
Are my files uploaded to a server?
No. pdfy processes your files inside your browser using your own device. Local tools do not upload documents. If you choose Save draft, that draft is stored only in this browser. You can confirm it in your browser's network panel: no file is ever sent.
Is it really free? Are there limits?
Yes, it is free with no sign up, no watermark on your output and no daily task limit. Because your device does the work, the only practical limit is your device's memory.
