Flattening bakes the current values of text fields, checkboxes and dropdowns directly into the page, then removes all interactivity — annotations, links, comments and form fields. The result is a static PDF nobody can edit or fill in further. Vector text and layout are preserved (pages are not converted to images).
What does flattening a PDF mean?
A filled form is still editable — anyone can click a field and change what you typed. Flattening a pdf bakes the current field values permanently into the page content and strips out every interactive element: form fields, annotations, links and comments. What you see becomes what everyone gets, forever.
How to flatten a PDF
- Drop your PDF onto the page. It never leaves your browser.
- Click “Flatten PDF” — one click, no options to get wrong.
- Download your static PDF. Text fields, checkboxes and dropdown selections are burned into the pages as plain content.
Unlike screenshotting pages, flattening keeps everything vector: text stays sharp and selectable, and the file stays small. Note the honest limit: highly complex markups (e.g. rich ink annotations) are removed rather than pixel-perfectly rasterized — for those, printing to PDF remains the gold standard.
