Compress PDF Online — Fit Any Upload Size Limit
Upload portals rarely accept large PDFs — many Indian government and exam websites cap documents at 100KB, 200KB, or 500KB, and email attachments have their own limits. This free PDF compressor reduces your file size while keeping the document readable, so your upload goes through the first time.
It is completely free with no signup and no watermark, and works on both phone and laptop. Compress mark sheets, ID proofs, application forms, and reports in seconds. If you are starting from a photo rather than a PDF, compress the image first with the Image Compressor and then convert it — that combination produces the smallest possible file for strict portals.
Frequently Asked Questions
How do I compress a PDF to 100KB?
Upload your PDF and run the compressor. If the result is still above your limit and your PDF is image-based, compress the source image first with the Image Compressor, then convert it back to PDF.
Will my document still be readable?
Yes — the compressor balances size and quality so text remains clear for reviewers and portals.
Is there a file limit?
No daily limits. Compress as many PDFs as you need, free.
