This tool needs JavaScript. Turn it on in your browser — or use the Telegram bot below, it does the same.

Choose a PDF: the tool shrinks the scans and photos inside step by step until the file is **under 100 KB**, keeping them as clear as the limit allows. Text stays text, and you see the size before you download.

Works in your browser: what you type or choose stays on your device and is not uploaded anywhere.

## Where you need this

- Certificates, mark sheets and ID scans for exam and job application forms
- Government portals that accept 50–100 KB per document
- Email attachments on a slow connection

## Questions

**Will a scan still be readable at 100 KB?**

A one-page scan usually is. Many pages in 100 KB get blurry: if the form allows, upload pages separately or choose 200 KB.

**The tool says 100 KB is too small. What now?**

The PDF has too many pages or large photos. Remove pages you don't need, or scan at a lower resolution, then try again.
