How does the image compressor work?
This tool uses your browser's built-in image processing capabilities (Canvas API) to re-encode your images at a lower quality setting. The entire process runs locally on your device — your images are never sent to any server. Not a single byte leaves your computer.
Frequently Asked Questions
Is it really free?
Yes, completely free with no hidden limits. We are funded by ads displayed on the page — we never sell your data or access your files. Compress as many images as you want, as often as you want.
Are my images safe?
Your images never leave your device. There is zero network traffic during processing — you can verify this by opening your browser's Developer Tools (Network tab). We physically cannot see or access your files.
What formats are supported?
You can compress and convert between JPEG, PNG, and WebP formats. Input any of these formats and choose your desired output format.
Why is my PNG file larger after compression?
PNG is a lossless format — the quality slider has no effect on PNG output. If you need a smaller file size, try converting to JPEG or WebP instead.
What is WebP?
WebP is a modern image format developed by Google that provides superior compression for images on the web. It typically achieves 25-35% smaller file sizes compared to JPEG at equivalent visual quality.
Does this work offline?
Yes! Once this page is loaded, you can disconnect from the internet and the tool will continue to work perfectly since all processing is done locally.
