## Answer

Drop your PDF into the compressor below. Start with Keep text for the smallest change in look; use Target size when a portal asks for 100 KB, 1 MB, or another exact limit. Processing never leaves your browser.

## Limits

- Target size stops at a readable floor (~50 DPI) instead of producing unreadable pages.
- Re-rendered pages keep a searchable overlay when the original had text; accents may drop from that layer.
- Password-protected files must be unlocked first.

## FAQ

### How do I compress a PDF without uploading it?

Use this page — compression runs in your browser. Choose Keep text, Max shrink, or Target size, then download.

### Can I compress a PDF to 100 KB or 1 MB?

Yes. Use Target size here, or open a dedicated size page such as compress to 100 KB or compress to 1 MB for a pre-set limit.

### Will compress keep my text selectable?

Keep text preserves selectable text and vectors. Max shrink and Target size re-render pages when needed and restore a searchable overlay when text exists.
