Your files stay on this device. Nothing is uploaded.

A 100 KB limit is common for signature pages, ID copies and single-page certificates. This preset lowers resolution step by step until the file fits. For multi-page documents, extract the pages you need first.

How it works

  1. Drop your PDF files.
  2. Pick lossless or strong, and a target size if you have a limit to meet.
  3. Compress and download.

This tool runs entirely in your browser. Your files are never uploaded, so there is no size limit and it works offline once loaded.

Common situations

Frequently asked questions

Is it really free and private?

Yes. Everything runs in your browser with open-source code; nothing is uploaded. No account, no watermark, no file-size limit other than your device's memory.

Will text stay selectable?

In lossless mode, yes. Strong mode rasterizes pages, so text becomes an image; use it for scans and photo documents, not for text you need to copy.

Why is my PDF not getting smaller?

Because it is mostly text and vectors, which are already compact. Only images have room to shrink.
