Compress PDF to 100KB

RUNS ON THIS DEVICE

Set a 100 KB target and the compressor keeps squeezing until your PDF fits, working locally in your browser the whole time.

The strictest limit on the web

A 100 KB ceiling shows up on the forms with the least patience: government e-services, competitive-exam registrations, and visa applications, where a photo, a signature, and each supporting document must fit its own tiny slot. These portals rarely explain a rejection beyond 'file too large', which leaves applicants rescanning at random settings. Choosing the target here replaces that guesswork with a controlled squeeze toward the number the form actually wants.

What stays readable at 100 KB

Expect one to two scanned pages to fit while remaining clearly legible; body text holds up, though fine print and faint stamps soften. The compressor gets there by redrawing every page with the same technology browsers use to show PDFs, then trying progressively lower resolution and JPEG quality until the file drops under 100 KB — always under, because a document sitting right on the boundary can still be refused. When a file genuinely cannot reach the target without turning to mush, you get the smallest readable version plus a straightforward note that the goal was missed, not a quietly wrecked document.

Where the work happens

All of it runs inside a background thread of your own browser tab. The PDF is opened, rendered, re-encoded, and reassembled locally, which matters when the file is an ID scan or a bank statement headed for an official portal. There is nothing to install and no separate download before the first compression. Password-protected files are declined with a clear message asking you to unlock them first, there is no cap on how many documents you process in a day, and downloads carry no watermark.

Frequently asked questions

Is my document uploaded while it compresses?

No. Every pass runs in a background thread of your own browser, which is the point for this size range — 100 KB targets usually mean ID scans and official forms that should stay private.

Can I copy text out of the compressed PDF?

No, because the output pages are images. That costs nothing on scanned documents; if your file came from a word processor and must stay selectable, hold on to the original and give the portal the compressed version only.

How many scanned pages fit under 100 KB?

Usually one or two while staying readable. Body text survives; faint stamps and fine print come out softer.

What happens if my PDF cannot reach 100 KB?

You receive the smallest version that stays legible together with a notice that the target was missed, so you know before you attempt the upload.
