How it works

Target is set to 500 KB — change it if your form allows a different size

Choose your PDF — it never leaves your device

It first tries a lossless clean-up. If that is not small enough, it turns each page into a picture and picks the sharpest resolution that fits

How to get a PDF under 500 KB

500 KB is enough for several scanned pages at good resolution. This tool tries a lossless clean-up first, which keeps text selectable. If the file is still too big, it turns each page into a picture and searches for the highest resolution and JPEG quality that fits under 500 KB.

Tip: if you have many pages, remove the ones the form does not need with the PDF splitter, so the pages you keep stay sharper.

What 500 KB does to a scan

On 22 Oct 2026 we ran two phone scans of an A4 document through this page (one page, 763 KB; three pages, 2.3 MB). The tool turns each page into a picture and picks the highest resolution that fits:

One page: 144 DPI, 490.3 KB.
Three pages: 144 DPI, 495.9 KB.
One page, black & white option: 144 DPI, 479.2 KB.
Three pages, black & white option: 120 DPI, 496.1 KB.

The three-page scan at the other sizes: 50 KB → 40 DPI · 100 KB → 50 DPI · 200 KB → 72 DPI · 300 KB → 100 DPI · 1 MB → 200 DPI · 2 MB → 200 DPI.

Frequently Asked Questions

Is my PDF safe? Does it get uploaded anywhere?

Your PDF never leaves your device. All compression happens inside your browser using JavaScript. No file is uploaded to any server. This is especially important for sensitive documents like mark sheets, certificates, and identity proofs.

What if the PDF is still over 500 KB?

The tool tells you if it cannot reach the target. This happens with many pages at a very small target, because each page needs some minimum size to stay legible. Remove pages you do not need with the PDF splitter, then compress again.

Will text in the PDF remain readable after compression?

If the lossless step is enough, nothing changes and text stays selectable. If the pages had to be turned into pictures, text is still readable but can no longer be selected or searched, and small print can get soft at very low targets. The result shows the resolution (DPI) used — 100 DPI or more reads comfortably.
