Compress JPG, PNG and WebP right in your browser. No upload, no watermark, no signup — safe for ID photos and private screenshots.
How to use Image Compressor
- Open the toolNo signup and nothing to install; it works as soon as the page loads.
- Set “Quality”
- Set “Max width (0 = keep original)”
- Read the resultChange any input and the result is recalculated immediately.
Nothing you enter leaves your device
All of the work happens inside your browser. Whatever you type is never packaged up and sent to a server, and no request this page makes carries it.
That makes it safe for contract amounts, personal details and internal documents you would rather not hand to a third party — close the tab and it is gone.
What this tool does not do
Image Compressor only does what a browser can do on its own — it talks to no backend service. So it keeps no history for you and syncs nothing across devices; if you need a record, copy or download the result.
It is also not a substitute for professional judgement. For legal, medical or tax decisions, treat the output as a starting point rather than a final answer.
Frequently Asked Questions
- Are my photos uploaded to a server?
- No. Compression uses the canvas API inside your browser, so your files never leave your device. That makes it safe for ID documents and private screenshots.
- How much smaller will my images get?
- Typically 50 to 80 percent smaller at quality 70 to 80, with little visible difference. Photos with lots of detail compress less than flat graphics.
- Is there a file size limit?
- No. Because everything runs locally, the only limit is your device memory rather than a server quota.
