Compress PDF to 300 KB

300 KB is a common upload limit for application forms, scholarship and job portals, and supporting documents. Drop your PDF here and the tool finds the sharpest version that still fits under 300 KB, trying stronger picture settings only as far as it has to. Text and page layout are never changed, and the PDF never leaves your device.

What fits in 300 KB

Typed documents of many pages usually fit without any visible change. Short scanned documents, such as a mark sheet, a certificate and an ID card together, usually fit with pictures that are still easy to read. Very long scans may need to be split.

Getting scans to fit

If you scan documents yourself, 150 dpi is plenty for reading on screen, and greyscale or black-and-white scans are far smaller than colour. A cleaner starting file keeps more detail after compressing.

Questions

How do I compress a PDF to 300 KB?

Drop your PDF into the box. Exact size is already set to 300 KB, so press Compress PDF and download the result. The new size is shown before you save it.

What if my PDF is already under 300 KB?

The tool tells you it is already under the limit and changes nothing, so you can upload it as it is.

Is 300 KB counted as 300,000 or 307,200 bytes?

The tool aims for under 300,000 bytes, the smaller of the two, so the file passes either way.

Will the PDF still be readable?

Text stays exactly as it was. Pictures are resized only as much as needed to fit, and the result says if they had to be made noticeably softer.

Is my file uploaded?

No. Everything happens in your own browser, so the PDF is never sent to a server.
