A File Compressor That Respects Your Privacy
Most online image compressors upload your file to their servers, process it there, and send it back. That means your personal photos, ID scans, and private documents pass through someone else's infrastructure. This tool doesn't do that. Compression runs entirely in your browser using JavaScript. The image data never leaves your device.
There's also no account wall. No "sign up to download" popup, no "free users get 5 compressions per day" limit. The tool is free to use as many times as you need, with no artificial restrictions. It works because the processing cost is zero on our end — your own CPU does the work.
Frequently Asked Questions
Is there a daily limit on how many images I can compress?
No limits. Compress as many images as you want, as often as you want. Since processing happens in your browser, there's no server cost to restrict.
Do you add watermarks to compressed images?
Never. The compressed output is a clean file with no branding, watermarks, or modifications beyond the compression itself.
What image formats are supported?
JPG/JPEG, PNG, WebP, and BMP. The tool outputs in the same format as your input by default, or you can use the convert tool to switch formats.
How does browser-based compression compare to server-based tools?
Quality is equivalent. Modern browsers have powerful image processing APIs. The only downside is that very large files (100MB+) might slow down your browser tab, while a server with more memory handles them easily.
