Tools in this guide
Overview
Edit PDF tools change appearance or metadata without full desktop publishing software. Rotate pages scanned sideways, add a visible watermark, sign a draft, flatten form fields, or attempt repair on a corrupted file.
Signing and watermarking are useful before sharing review copies. Flattening merges form values into page content for distribution. Metadata Editor updates title or author fields when preparing archives.
Destructive edits should be tested on a copy. Always open the downloaded file to confirm page order and orientation.
How to choose
- Wrong scan orientation → Rotate PDF.
- Draft stamp or logo → Add Watermark.
- Signature on a contract → Sign PDF.
- Forms that must not change → Flatten PDF.
- Broken file → Repair PDF.
Frequently asked questions
Is Sign PDF legally binding?
Laws vary by jurisdiction and document type. These tools create visual signatures for convenience, not certified digital signature services.
Can I undo flatten?
Flattening is typically irreversible. Keep an unflattened master copy.
Will watermark tools remove existing watermarks?
No. They add new overlays; they do not remove third-party DRM or stamps.
