How to use this tool — guide & FAQ

How to compress a PDF online free

Large PDFs are a pain to email, upload to a portal, or send on WhatsApp. Compressing shrinks the file size while keeping the document readable — and it all happens in your browser, so your file is never uploaded to a server.

How to compress a PDF

  1. Upload the PDF you want to shrink.
  2. Pick a compression level, or set a target size — for example under 100 KB, 200 KB or 500 KB.
  3. Download the smaller PDF.

Compress a PDF to an exact size limit

Many Indian exam and government portals — SSC, UPSC, state boards, scholarship and KYC forms — cap uploads at a specific size like 100 KB, 200 KB or 500 KB. Use the target-size option to hit the exact limit without guessing, so your form isn't rejected for an oversized file.

FAQs

Will the quality drop? A lighter setting reduces quality slightly; for most text documents it stays perfectly clear. Choose a higher-quality level if the PDF contains photos.

Is it free and private? Yes — no account, no watermark, and the file is compressed in your browser, not uploaded anywhere.

Can I compress scanned PDFs? Yes. Scans are usually the largest files, so they compress the most.
