Compress a JPG image

JPG is still the format almost every camera, phone, and photo app produces by default, and it's accepted everywhere. Drop your photo below and we'll find the highest quality that fits your target size.

Your images stay on your device. Compression happens in your browser and files are never uploaded to our servers.

Compressing JPG files

Best for photos, not screenshots

JPG's compression is built around smooth gradients and natural detail, the kind found in photos. Screenshots and graphics with flat colors or sharp text tend to look blurry or blocky at low JPG quality, PNG usually holds up better for those.

No transparency

JPG can't store a transparent background. If your image has one, saving it as JPG fills it with a solid color instead. Use PNG or WebP if you need to keep transparency.

Universal compatibility

Every browser, phone, email client, and piece of software from the last three decades opens a JPG. If you're not sure what format an upload form expects, JPG is the safest default.

Questions about compressing JPG

What's the difference between JPG and JPEG?+

Nothing. They're the same format under two different file extensions, a holdover from older Windows systems that only allowed three-letter extensions.

Will compressing my JPG lower its quality?+

Some quality loss is unavoidable once you shrink a JPG below its original size, since JPG is a lossy format. We find the highest quality setting that still hits your target, so the loss is as small as possible.

Should I use JPG or WebP?+

WebP usually produces a smaller file at the same visual quality. Reach for JPG specifically when you need compatibility with an older system or a form that only accepts JPG.
