Compress PDF to 100 KB for UPSC
Get your certificate or document PDF under the 100 KB limit that UPSC application forms commonly require.
Files are optimized losslessly when possible. To guarantee an exact size, larger files are converted to images, which can soften text and remove the selectable text layer.
Compressing PDFs for UPSC applications
Indian government recruitment portals are strict about upload sizes. For UPSC One Time Registration and exam application forms, scanned documents and certificates often need to be small, and 100 KB is a frequently requested limit for PDF uploads. The exact cap can change between notifications, so always check the instructions on the official UPSC portal before you submit.
KiloPDF compresses your certificate or document PDF to 100 KB right in your browser. A scan of your degree, category, or identity certificate never gets uploaded to a third-party server, which matters when the document carries personal details.
Choose your file, confirm the 100 KB target, and download the result. If the original is already under 100 KB we keep it untouched at full quality.

Frequently asked questions
Is 100 KB the right size for UPSC applications?
100 KB is a commonly requested target, but limits vary and change over time. Check the exact requirement on the relevant portal or provider before you upload or send.
Are my files uploaded to a server?
No. Compression runs entirely in your browser using WebAssembly. Your PDF never leaves your device, which makes this safe for KYC, banking, and government documents.
How do you hit exactly 100 KB?
We re-encode each page as an image and search across quality and resolution settings until the rebuilt PDF lands at or just under 100 KB, keeping the best quality that still fits.
Is it really free with no watermark?
Yes. No sign-in, no per-hour task caps, no watermark, and no file-count limits, unlike most incumbents.
Will the text stay selectable?
When the file already fits or can be optimized losslessly, text stays sharp and selectable. To guarantee a smaller exact size we rasterize the pages, which is exactly what portal uploads need. If you need selectable text, keep your original.
