Compress PDF to 300 KB
Pick a file and Fileloka finds the highest quality that still fits under 300 KB, so you don't have to guess with a slider. It keeps the text selectable when it can, and everything runs on your own device.

When do you need a PDF under 300 KB?
300 KB leaves a bit more room for two or three pages, say a double sided transcript or a certificate with its attachment, without pushing the quality down too far.
How realistic is 300 KB?
| Document | To 300 KB |
|---|---|
| 1-page scan (phone photo) | Easy, stays sharp and in colour |
| 3-page scan | Fine, still good quality |
| 10-page scan | Doable with black & white ticked |
| 10-page text PDF (from Word) | Usually fits already, text intact |
These are estimates for A4 pages. Real results depend on what's in the document, and you always see the final size before downloading.
How it works
- Pick a PDF or drop it on the page. The 300 KB target is already selected.
- Click Compress. Fileloka tries to keep the text first, then looks for the best image quality that fits.
- Check the before and after sizes and the Under 300 KB badge, then download.
Questions about this tool
How do I compress a PDF to 300 KB on my phone?
Open this page in Chrome or Safari, tap the file area and pick the PDF from your files. The 300 KB target is already selected, so just tap Compress and download the result. There's no app to install.
Why is the result a little under 300 KB instead of exactly 300 KB?
That's on purpose. Some portals count 1 KB as 1000 bytes and others as 1024. Fileloka aims under the 1000 byte version of 300 KB, so the file passes either way, at the highest quality that still fits.
Should I pick 200 KB or 300 KB?
Pick whatever the portal asks for. A looser limit means more quality is kept, so if 300 KB is allowed there's no reason to squeeze down to 200 KB.
Will the text in my PDF stay selectable?
When it can, yes. Fileloka first shrinks only the photos and scans inside the PDF and leaves the text alone. Pages are turned into images only if that isn't enough, and the result tells you which one happened.
Is it safe for passports, IDs and contracts?
Yes, because the file isn't uploaded. Your own browser does the compressing and no server ever receives the document. Try it: load the page, turn on airplane mode, and the tool still works.
