This page starts with the target already set to 100 KB — the limit that visa applications, university portals and government upload forms ask for most often. Drop your PDF and download a file that fits.
The compressor does not simply crush the file to the smallest possible size. It searches for the best quality that still comes in under 100 KB, so your document stays as readable as the limit allows instead of arriving as an unreadable smudge.
If your PDF has many pages, reaching 100 KB may require heavy compression. When a single page cannot fit the budget, the document is split into parts that each satisfy the limit.
How to use it
Drop your PDF onto the box, or tap it to pick the file from your device.
The target is already set to 100 KB, so you do not need to choose anything — change it only if your form allows more.
Press Compress; the pages are re-rendered while the tool searches for the best quality that still fits.
Download the finished PDF, or the ZIP of parts if a single file could not reach the limit.
Supported formats and limits
Input
PDF (any version)
Output
PDF under your target size
Target sizes
100 KB by default; any KB or MB value
Where it runs
Entirely in your browser; nothing uploaded
File size
Limited by your device memory, not by a server quota
Not for: Keeping selectable text — compression rasterises pages to hit an exact size, so the result is a visual PDF.
Frequently asked questions
Are my files uploaded to a server?
No. This conversion runs entirely inside your browser using your own device’s processing power. The file never leaves your computer or phone, which is why it also works when your connection drops.
Why does my file come out at 96 KB and not exactly 100 KB?
The limit is a ceiling, not a goal. The tool returns the highest-quality version that stays under your number, which normally lands just below it.
The result is unreadable — what can I do?
Remove pages you do not need before compressing, or raise the target if the form allows. Scanned pages full of photographs need far more data than text pages to stay legible.
