Compress Image
Make your images smaller without wrecking them.
Everything is processed on your device. Nothing you upload or type is sent to a server, and nothing is stored.
Compress Image online
Photos straight from a phone or camera are far bigger than they need to be for a website or an email. Pick a quality level, watch the size drop, and download the result. Compression happens on your device, so your photos are never uploaded.
How to use compress image
Add your images
Drop in one or more JPG, PNG or WebP files.
Pick a quality level
Around 80% is the sweet spot for most photos — a large size saving with very little visible difference.
Compress
Each image is re-encoded in your browser and you see exactly how much was saved.
Download
Save images individually, or download them all at once.
Frequently asked questions
How much smaller will my image get?
Photographs typically shrink by 60–80% at a quality setting of 80, with little visible change. Images that are already optimised, or simple graphics with flat colour, will save much less because there is less redundant detail to discard.
Will compressing make my photo look worse?
JPEG and WebP compression is lossy, so some detail is always discarded. At quality 80 and above the difference is very hard to see at normal viewing size. Below about 60 you will start to notice softness and blocky patches in areas of smooth colour.
What happens to PNG images?
PNG is a lossless format, so a quality slider does not apply in the same way. PNGs are re-encoded as WebP or JPEG when that produces a meaningfully smaller file — the tool tells you which format it used.
Does compression remove EXIF data?
Yes. Re-encoding drops embedded metadata such as GPS location, camera model and timestamps. That is usually a benefit when posting photos publicly.
Are my images uploaded anywhere?
No. Everything runs inside your browser using the standard Canvas API. Your photos never leave your device.
