# Compress a PDF to 30 KB

> Shrink a PDF under 30 KB in your browser. Pre-set to a safe 29 KB target. Honest when one page cannot stay readable at that size.

## Answer

Drop your PDF into the compressor below. It’s set to 29 KB so it passes a 30 KB limit either way the portal counts. **One plain page** is realistic; photos and busy colour scans often cannot fit and stay readable.

## What fits comfortably

One clean text or certificate page cropped to the document edges.

## What is squeezed

Rarely more than one page. Photo-heavy pages may hit the legibility floor.

## Context

30 KB sits between the ultra-tight 20 KB fields and the more common 50 KB caps on supporting-document uploads.

Expect the compressor to use a low DPI pass. Check seals and small type in the preview before you submit.

## Tips

- **Crop first** with [Crop pages](https://mypdf.space/tools/crop-pages) so table edges and shadows are not in the frame.
- **One page only** — delete extras with [Delete pages](https://mypdf.space/tools/delete-pages).
- **Rescan in black and white** if the phone photo is grey and soft.

## FAQ

### How do I compress a PDF to 30 KB?

Use this page. The tool is pre-set to 29 KB, tries a lossless pass first, then lowers resolution until the file fits or hits the readable floor.

### Why 29 KB instead of 30 KB?

Some portals count 1 KB as 1,000 bytes. 29 KB in the tool stays under 30,000 bytes either way.

### Does this upload my file?

No. Compression runs in your browser.
