Compress PDF to 100 KB
Shrink any PDF to 100 KB or less automatically. The tool keeps adjusting quality until your file fits.
Why 100 KB matters for Indian form uploads
A huge number of Indian government portals hard-cap attachments at 100 KB — and simply reject anything larger with a cryptic error. This tool auto-iterates JPEG quality downward until your file lands at or below 100 KB, saving the manual trial-and-error of trying 60%, 50%, 40% yourself.
Portals that commonly enforce a 100 KB limit
- UPSC — Civil Services, NDA, CDS application documents
- SSC — CGL, CHSL, MTS signature and photo PDFs
- Banking & IBPS — PO, clerk, specialist officer form attachments
- NTA / exam portals — category certificate, photo ID uploads
- State PSC portals — most follow the 100–200 KB standard
What stays intact
Page dimensions, page count, and reading order are preserved exactly. The tool re-renders each page as a compressed JPEG — text remains legible for signatures and printed certificates even at aggressive compression. If your PDF has only typed text (no scans), the output stays very sharp because text areas compress well.
How to use this tool
- Upload your PDF.
- Click Compress — the tool auto-iterates JPEG quality until the file is ≤100 KB.
- Download the compressed PDF and upload it to your portal.
Frequently asked questions
What if the tool can't reach 100 KB?
Extremely large scans (20+ MB) may not reach 100 KB without becoming unreadable. In that case, compress to the smallest readable size and split the file if the portal allows separate uploads.
Will my signature remain clear?
Yes — signatures are high-contrast black-on-white and survive JPEG compression well. Even at 50% quality a wet-ink signature stays clearly legible.
Is the layout preserved?
Page dimensions are kept exactly. Only image quality is reduced — margins, fonts, and page order are untouched.
Can I compress a multi-page PDF?
Yes. All pages are processed together and the output is a single compressed PDF, not separate files.
Is my PDF uploaded to a server?
No — compression runs entirely in your browser. Your document never leaves your device.
