Compress PDF to 300 KB

Get any PDF under 300 KB for an upload form: scans and photos inside are re-compressed only as much as needed, and text stays sharp. Runs in your browser; your PDF is never uploaded.

Scanned documents, certificates and photo PDFs shrink the most. Runs on your device; the PDF is never uploaded.

KB

Images are re-compressed and, only if needed, scaled down until the whole PDF fits. Text stays sharp.

How it gets your PDF under 300 KB

Most large PDFs are large because of the pictures inside: scanned pages, photos and certificates stored as JPEG images. The tool finds those images, re-compresses them a step at a time, and saves the PDF after each step until the whole file is under 300 KB. If quality alone isn’t enough, it scales the images down a little. Text, lines and fonts are left exactly as they are.

Tips

  • Scanned at a very high resolution? The tool scales images down only if it has to, so documents usually stay readable.
  • Several separate scans? Compress each one, or keep the most important pages if the form limit is very small.

Other sizes: 100 KB, 200 KB, 500 KB, 1 MB. Images instead? Compress an image to 100 KB.

Questions

How do I compress a PDF to 300 KB?

Drop the PDF. The limit is already set to 300 KB; the tool re-compresses the photos and scans inside until the whole file fits, then you download it.

Will the text stay sharp?

Yes. Text, lines and fonts are not touched; only the images inside the PDF (scanned pages, photos) are re-compressed.

What if it can’t get under 300 KB?

You get the smallest version possible and a note. PDFs made only of text are usually already small; very long scans may need to be split.

Is my PDF uploaded?

No. It is processed in your browser, which matters for ID documents, mark sheets and certificates.

Does it work with password-protected PDFs?

No. Remove the password first (you need to know it), then compress.
