Repair a PDF handles a damaged document, Grayscale PDF simplifies colors, and Flatten PDF annotations freezes annotations and interactive layers. Start with the tool matching the symptom.

How to use

  1. For a file that is too heavy, start with Compress a PDF and compare the resulting size before sharing.
  2. If the document must load progressively on the web, use Optimize PDF for Web instead of standard compression.
  3. To meet a size limit, go through Split a PDF by size, then check each part separately.
  4. For a fragile or colorful document, try Repair a PDF, then Grayscale PDF or Flatten PDF annotations depending on the need.

Frequently asked questions

Which tool makes a PDF lighter?

Compress a PDF reduces the file size of a PDF for faster sharing. If the file must be read on the web, Optimize PDF for Web loads it progressively. To split by a limit, use Split a PDF by size.

Can I repair an unreadable PDF?

Repair a PDF rebuilds a damaged or unreadable PDF document. It is the first option to try if the file does not open correctly. To remove annotations, use Flatten PDF annotations instead.

What is Grayscale PDF for?

It converts colors and images into a black and white document. That can suit a sober print job or a more uniform document. To reduce size, also look at Compress a PDF.

What if compression is not enough?

First try Compress a PDF to reduce size. If a size limit remains, use Split a PDF by size to obtain several parts. For web display, Optimize PDF for Web can also help. Always check that the content stays readable after the operation.

When should I repair instead of optimize?

Repair a PDF fits when a document is damaged or unreadable. PDF Optimize is more about making a file lighter, preparing it for the web, converting to grayscale or splitting by size. If the file opens badly, start with Repair a PDF. If it opens well but stays too heavy, move to Compress a PDF.
