Compress PDF to 100 KB

Online applications often cap each uploaded document at a fixed size, and 100 KB is one of the most common: certificates, ID proofs, mark sheets and signed forms for job, exam, university and government portals. The limit is per file, so each PDF is aimed under 100 KB on its own.

Typed pages from Word or a website are small, and several usually fit. Scanned pages are photos: as a rough guide, one or two scanned pages fit comfortably, while five or more usually need 72 dpi or grayscale. The result line tells you what it took, so you can check that small print still reads well.

You get the smallest version it made, a plain reason (for example, the text and fonts alone are over the limit), and two ways forward: grayscale photos, or splitting the PDF into parts that each fit. It never pretends a file fits when it doesn't.

We aim under 1 KB = 1,000 bytes, the stricter of the two. A file that fits here also passes an upload form that counts 1 KB as 1,024 bytes, so you never have to guess which one a site uses.

No. Your files are processed on your own device by your browser. They never touch our servers, so there are no upload waits, no size caps from us, and nothing to delete afterwards.
