How to compress a PDF

  1. Open Compress PDF on A2Z Edit.
  2. Upload the oversized PDF.
  3. Choose a compression level that balances size and clarity.
  4. Run compression and compare the new file size.
  5. Download the smaller PDF and spot-check image-heavy pages.

Why it matters

A smaller PDF clears mailbox limits and speeds up sharing without reprinting everything.

Tips

  • If size is still high, remove unused pages before compressing again.
  • For photo-heavy files, slightly stronger compression usually helps most.
  • Always open a page with fine print after compressing to check legibility.

Frequently asked questions

Will text stay selectable?

Compression targets size; existing text layers typically remain, though results depend on the file.

How small can it get?

It depends on images and embedded fonts. Highly scanned PDFs shrink more than text-only ones.

Is this the same as converting to JPG?

No. Compression keeps a PDF. Converting to images is a different workflow.
