How image compression works
Most photo compression is lossy: it discards detail your eye is least likely to notice to make the file dramatically smaller. Formats like JPEG and WebP let you trade a little quality for a lot of size, and at sensible settings the difference is invisible on screen.
The right balance depends on use. For the web, smaller and faster wins; for printing, keep more quality. This tool lets you shrink one image or many at once, entirely in your browser.
When to compress
Compress before emailing photos, uploading to a website or storing large batches, anywhere file size matters. Smaller images load faster, which also helps a site's performance and search ranking.
Because the work happens on your device, your photos are never uploaded. Pair compression with a resizer if the image is also larger in dimensions than it needs to be.
Frequently Asked Questions
Does compressing reduce image quality?
Some quality loss is possible with lower settings, but at moderate levels the difference is usually invisible while the file gets much smaller. You can tune the quality slider to balance size and clarity.
Which formats can I compress?
Common web image formats including JPG, PNG and WebP are supported.
Are my images uploaded anywhere?
No. Compression happens entirely in your browser, your photos are never sent to a server.
