Flatten PDF Forms — Make Filled Fields Permanent

Flattening converts interactive form fields — text boxes, checkboxes, dropdowns — into ordinary page content. The filled-in values stay visible exactly as they appear, but the fields themselves are removed, so nobody can click in and change an answer afterwards.

Flatten right before you send a completed form: job applications, signed agreements, tax or insurance paperwork. It prevents accidental edits, avoids viewers that render form fields inconsistently, and makes the document print exactly as it looks on screen.

The tool tells you no form fields were found and returns an unchanged copy of your document instead of failing. That makes it safe to run on mixed batches where only some files contain forms.

No. Field appearances are regenerated from their current values before merging, so the flattened page shows the same text, checks and choices in the same place. Only the interactivity is removed.

No. Flattening removes form interactivity but anyone can still view the file normally. If you need to restrict opening or editing with a password, use a PDF password tool — the two protections combine well for sensitive forms.

Yes — Pixoate supports batch and bulk processing. Switch to Batch mode, add up to 60 PDFs on Premium or 200 on Pro, set your options once, and every PDF is processed with the same settings before you download a single ZIP. Bulk processing is a Premium feature; the output uses the same quality and settings as single mode.

Yes — with bulk processing you configure the settings a single time and they apply to every item in the batch — up to 60 PDFs on Premium or 200 on Pro. There is no need to repeat the setup per item, and Temporary uploaded and generated files are processed securely and deleted automatically.

Almost always one of three things. The file is over the 20 MB free upload limit — Premium takes 50 MB and Pro 120 MB. The format is not one this tool accepts, so check the list shown on the upload panel. Or the file is not really the format its name says: renaming a file does not change what is inside it, and that is the reason a valid-looking PDF gets refused.

Page content is preserved, but anything that depended on the original file being interactive can behave differently — form fields, layers and annotations may be flattened into the page depending on the operation you ran. If you need the fields to stay fillable, do the flattening step last. Keep the untouched original until you have checked the output end to end.

Flatten PDF supports free standard use within the published processing allowances. Free downloads are clean — no watermark. No signup is required for standard tool use. Photo effects and AI edits have a web-size limit on Free, with the original-resolution result available through Premium or one credit. Crop, resize, rotate, compress and convert stay full size. Premium supports batches of up to 60 files, with the applicable plan limits shown before processing.

No — Flatten PDF runs in the browser on desktop and phone. There is nothing to install, no trial to start, and no license to buy before you can see whether it does what you need. Try it on the file you are actually stuck with rather than a sample.
