About this tool
Two modes. Pick a quality level yourself, or enter a target size in KB and the tool searches for the highest quality that fits under it, reducing dimensions only when quality alone is not enough. Pages are re-rendered as optimised JPEGs; 60-90% compression is typical for scans.
The trade-off: pages become images, so text stops being selectable. For scanned PDFs that's no loss at all; for text-heavy digital PDFs, try a lighter setting and check the result. Either way the document is processed locally on your device.
How it works
- Drop your file(s), they are read locally on your device.
- Set the options you need and run the tool.
- Download the finished PDF, images or text.
Frequently asked questions
How do I compress a PDF to exactly 100 KB or 500 KB?
Switch the mode to target size and type the limit in KB. The tool tries progressively lower quality settings until the file fits, and shrinks page dimensions only as a last resort. If the target is physically unreachable it says so and gives you the smallest it could make.
Why is the text not selectable after compressing?
This tool compresses by re-rendering each page as an optimized image, which is what makes scans so much smaller. The visual content is identical but the invisible text layer is gone. If you need selectable text, keep the original alongside the compressed copy.
Is this safe for bank statements and signed contracts?
Yes. The document is rendered and rebuilt entirely by your browser. It never leaves your device, so there is no copy on anyone's server.
