Make PDF forms non-editable
Turn checkboxes and fillable fields into permanent, static content, while the rest of the page's text stays selectable and copyable as normal.
Lock down an entire page as a flat image, with your choice of resolution, so nothing on it can be selected, copied, or edited anymore.
Add multiple PDFs and flatten them all in one action instead of doing it file by file. Part of Dely PDF Pro.
The entire process runs directly in your browser. No file is ever sent to a server, so your personal documents never leave your device.
Lock a completed form or agreement, like a registration or approval, so its fields can't be changed anymore after it's submitted or signed.
Turn an important document, like a contract or official report, into an image so its text can't be copied or edited with a PDF editor.
Archive the final version of a document in a form that can no longer change, safe to keep as your long-term record.
Raster mode locks in the page's exact appearance, fonts included, so it looks and prints identically on any device, even ones without the original fonts installed.
Select or drag and drop a PDF from your device. Everything is processed directly in your browser, never sent to any server.
Pick Form (stays selectable, only locks the fields) or Raster (locks everything down as an image, with your choice of DPI).
Your flattened PDF is ready to download instantly.
