Need to shrink a PDF down to exactly 100 KB for an online application form, email attachment, or government portal? Our free in-browser PDF compressor reduces PDF files to under 100 KB while keeping the text crisp and readable.
Your file never leaves your browser.
Most files process in under a second.
Output is byte-for-byte yours.
A huge number of Indian government portals, university application forms, and job sites cap PDF uploads at 100 KB. If your PDF is even slightly over the limit, the upload fails — usually with a cryptic error message. Compressing to 100 KB or less is the fastest way to get past that wall.
Our tool re-encodes the pages of your PDF at a lower image DPI and strips redundant metadata. For most single-page or text-heavy documents, that's enough to land well under 100 KB without the page becoming blurry. Everything happens locally in your browser — your file is never uploaded to our servers, which means it's safe to use with personal photos, IDs, and confidential documents.
Start with a clean source — convert from Word or Google Docs rather than a phone scan if you can. Avoid embedded high-resolution photos. If your PDF is mostly a scanned image, consider reducing the page count or splitting into multiple files. Black-and-white scans compress dramatically better than full-color ones.
Yes, completely. There's no signup, no watermark, and no daily limit.
Yes. We preserve text quality and only reduce embedded image DPI, so the words stay sharp.
Absolutely — the compression runs entirely in your browser. Your file never leaves your device.
Yes, though heavy multi-page PDFs may need more aggressive compression. We pick the best preset automatically.
