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. Pick Target size and tap the 100 KB, 200 KB or 500 KB preset (or type your own limit) to hit it 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.
