Flatten

Step by step

How To Flatten a PDF

Make a fillable PDF read-only — or turn every page into a picture — without leaving the browser.

1. 1

   Upload your PDF

   Drop in the fillable form or annotated document you want to lock down. The screen takes it from there — no settings are needed before the file is in. Files are deleted after 2 hours.

2. 2

   Choose what to flatten

   Flatten everything renders every page to a picture — form fields, annotations and text all become part of the image; it is print & scan in one step. Flatten only form fields bakes the widgets — our filled form's “Dana Tester” came back as plain text — while text, images and annotations stay as they are. Behind More options sit the image-resolution steps.

   Flatten & download

   Press Flatten PDF and the rebuilt file lands on the ready page — page count kept, Download right there. In our one-page membership form the fields came out uneditable either way: baked into the content in one mode, one flat image in the other.

   

• Fields become content

  Only form fields bakes the widgets — filled values included — so the file stops being fillable.

• Rasterise everything

  Flatten everything turns each page into a picture — fields, annotations and text in one image.

• Print & scan shortcut

  The everything mode is the modern photocopier — a flat, uneditable copy in one run.

• Resolution on tap

  75, 100, 150 or 220 dpi behind More options — 150 is the balanced default.

• Page count kept

  One page in, one page out — the document's structure is preserved.

• Private by default

  No account, no watermark — and every file is automatically deleted after 2 hours.
