Squeeze a PDF under 100 KB without touching its text.
Or choose a file. It is opened and rewritten on your device and never uploaded. Text is never touched — only the images inside.
Working on your device…
Your PDF is opened and rewritten in this browser. It is never uploaded, and nothing about it is stored.
A hundred kilobytes is a severe limit for a PDF, and it is one that government and university forms still set. A text-only document will already be under it; anything with a scan or a photograph in it will be many times over.
This works down through progressively smaller image settings until the document fits, and stops at the first one that does. Text, fonts and vector artwork are never touched, so the document stays searchable — and if 100 KB cannot be reached without destroying it, you are told that rather than handed a pile of blurred pages.
Application systems built for text documents often cap uploads around this size, having never anticipated scans.
Scanners default to print resolution, so a single scanned page routinely arrives at several megabytes.
Photographing a signature page and saving it as a PDF produces a file dominated entirely by one large image.
Drag a file onto the page or choose one. It is opened on your device and never sent anywhere.
You see the original size, the target, and what the document came out at. Text, fonts and vector artwork are never touched — only the images inside are re-encoded.
If the target cannot be reached without destroying the document, you are told how small it can honestly go rather than handed a rasterised page.
For one page, often. For several pages of scans, frequently not — and the tool will tell you the smallest it can honestly reach instead of flattening the text to get there. Splitting the document is usually the right answer at that point.
Yes. Only the images inside the document are re-encoded. Text that could be selected, searched and copied before still can be. This is the difference between this tool and one that converts each page to a picture.
Because text is tiny. A page of prose is a few kilobytes of instructions and a font subset. Nearly all the weight in a large PDF is pictures, which is why that is the only thing this touches.
No. The document has to be readable to be rewritten, and since everything happens in your browser there is nowhere to send it to be unlocked. Remove the password in your PDF reader first.
