Compress an image
Too big for an upload form, e-mail or website? Compress your photos here for free: the same image, the same dimensions, a fraction of the file size — without them ever leaving your device.
Everything happens in your browser. Your photo is never uploaded.
Compress or resize?
There are two ways to make a photo smaller. Resizing lowers the number of pixels: fine for e-mail or a listing, but you genuinely give up image information. Compression leaves the dimensions intact and only stores the file more efficiently. The photo stays just as sharp on your screen but weighs a fraction of the original.
Rule of thumb: if the photo has to stay at a certain size — for print, a photo book or an upload form with pixel requirements — you compress. If it can simply shrink in pixels too, use our resize tool; that combines both.
How it works
Pick a compression level and a file format, then drag your photos into the box. Your browser reads and re-encodes each file on the spot; next to each photo you see how many percent smaller the result is, with a download link. Change the settings and every photo is processed again — your original always stays unchanged on your device.
Metadata disappears automatically
Re-encoding rebuilds the photo from scratch. Hidden metadata such as the GPS location, camera details and timestamps doesn't travel along — for photos that go public, that is exactly what you want. Curious what your original contains? Check it with our EXIF viewer below.
Frequently asked questions
Is my photo uploaded?
No. Compression happens entirely in your browser, on your own device. Even large batches of photos never travel to a server.
What is the difference with resizing?
Resizing lowers the number of pixels: the photo literally gets smaller. Compression keeps the dimensions and stores the photo more efficiently, with slightly less detail. If a photo has to stay under an MB limit but remain sharp at full size, compression is the right choice.
Will I see a quality difference?
At the light and balanced levels almost never; you would only spot the difference when zooming in far. The strong level squeezes the file hardest and can become visible in smooth colour gradients. Just try a level — your original always stays unchanged.
Should I pick JPG or WebP?
At the same quality, WebP is roughly a quarter to a third smaller and works in every modern browser. JPG is the safest choice when the photo has to be uploaded or opened somewhere you don't control the software.
