Why flatten a form?

What changes
The fields disappear and their contents are drawn onto the page. The document looks the same but can't be filled in again.

Can I undo flattening?+
No — keep your original file if you might need to edit the answers.
Does it flatten comments and annotations?+
It flattens form fields. Comments are left as they are.
My PDF says it has no fields?+
Then it's already flat — nothing to do.
Is this tool really free?+
Yes. No sign-up, no watermark, no daily limits. It's free because it runs on your own device.
Are my files uploaded to a server?+
No. Your files are processed entirely inside your browser and never leave your device. You can even disconnect from the internet after the page loads.
Is it safe for confidential documents?+
Yes. Because nothing is uploaded, contracts, bank statements, IDs and medical records stay on your device. There's no server copy that could be stored, shared or leaked.
Do I need to create an account or install anything?+
No. Open the page and use the tool — no account, no email, no extension and no download.
How large can my files be?+
There's no fixed limit. Because the work happens on your device, the practical limit is your browser's memory — files of a few hundred MB usually work fine on a laptop. Very large files are faster in the Mac app.
Which browsers are supported?+
Any modern browser: Chrome, Safari, Edge, Firefox, Brave and Opera, on Mac, Windows, Linux, iPhone, iPad and Android.
Will my file have a watermark?+
No. Your result is exactly what you made — no watermark, no added pages and no branding.
Is there a desktop app?+
Yes — ilovepdfmac for Mac does all of this and much more (Word, Excel and PowerPoint to PDF, a full PDF editor, real compression) offline, for a one-time $9.99.
