Optimize and Repair PDF Tools
Best for users whose PDF is too large, broken, slow to send, or needs cleanup before upload, email, storage, or compliance review.
Category guide
How to choose the right optimize & repair workflow
Use this category when the PDF technically exists but blocks the next step because it is too large, malformed, slow to load, hard to reuse, or carrying hidden data. These workflows improve delivery quality before upload, email, storage, printing, or review.
- Use Compress PDF when file size is the primary blocker for email, upload portals, or storage.
- Use Repair PDF when the document is broken, unreadable, or exporting incorrectly.
- Use Deskew PDF when scanned pages are tilted and need readability cleanup before OCR or sharing.
- Use Remove Metadata or Sanitize PDF when cleanup is about privacy, hidden data, or external distribution.
