PDF Tools

Work with PDF files in the browser: fill AcroForm fields, add text, date, signature, image, and highlight overlays, validate required fields, flatten or keep fields editable on export, and compress PDFs to reduce file size. Upload a document, complete the edits on the page, then download the result—processing stays on your device for these workflows.

Fill vs compress

Use Fill PDF Form when you need fields, signatures, or overlays. Use PDF Compressor when the goal is a smaller file for email or upload limits. Related format changes (PDF↔Word, merge, PDF to JPG) live under Converters.

Limits

XFA-only forms are not supported. Compression and flattening are irreversible for the exported file—keep the original if you may need to edit again.
