Exact-size PDF compressor

Compress a PDF to Exactly 50 KB

Portals do not accept "around 50 KB". This preset drives the PDF encoder to land on 50 KB and shows the achieved size before you download anything.

Compress to 50 KB now
The tool opens with the 50 KB target already set | nothing is uploaded anywhere.

Supporting-document uploads across Indian portals publish hard size caps, and a PDF even slightly over the limit bounces without a readable explanation. The usual fix is a desktop suite and a trial-and-export loop that guesses at quality settings.

This page removes both. The compressor opens with 50 KB pre-filled as the target, runs measured encoder passes on your device, and keeps the best result it can prove is smaller than your original. Text and vector content is never rasterised, so documents stay crisp and searchable.

At 50 KB only text-heavy PDFs with little or no imagery can make the target; the tool tells you honestly when a file cannot get there without destroying pages.

Will a PDF really reach 50 KB?
At 50 KB only text-heavy PDFs with little or no imagery can make the target; the tool tells you honestly when a file cannot get there without destroying pages.
Does compression remove pages or text?
No. Pages, text and vectors stay intact; the encoder re-encodes large embedded photographs and drops redundant objects it can prove are unused.
Is my document uploaded anywhere?
No. Every pass runs inside your browser tab using local memory; the file and every intermediate version stay on your device.
What if the target is impossible for my file?
The tool reports the smallest size it achieved and keeps the better of the original and the result, so you never download a worse file.
