Image Compressor is a free tool that compresses up to 100 images at once entirely in your browser. Compress to an exact target file size in KB, reduce by a target percentage, or set the quality by hand. Choose the Auto format that keeps the smaller of JPEG and WebP, or save as JPEG, WebP or PNG, optionally resize down, and keep the original when compression would make it larger. Re-encoding removes EXIF and GPS metadata. Tap any result to compare the original and compressed versions, and download each file or all of them as a ZIP. Your images are never uploaded and stay on your device.

Frequently asked questions

Can it compress 100 images at once?

Yes, up to 100 per batch. Everything runs on your device, so a big batch depends on your computer's memory and speed. On older phones or low-memory devices, very large or very many images may slow down, so just do them in smaller groups.

Are my images uploaded anywhere?

No. Everything happens inside your browser, so your files never leave your device and nothing is sent to a server.

How do I compress to an exact size, like 200 KB?

Pick the Target KB mode and type the size in KB. The tool searches for the highest quality that fits under your target, and if even the lowest quality is still too big it gently reduces the dimensions until it fits. This is handy for forms and portals with strict upload limits.

What does the Auto format do?

It encodes each image as both JPEG and WebP and keeps whichever one comes out smaller. WebP usually wins for photos, so Auto is the easy way to get a small file without picking a format yourself.

Does it remove EXIF and GPS metadata?

Yes. Re-encoding an image strips camera details, GPS location and other metadata. That trims a little extra size and is good for privacy. The exception is Keep original when the result ends up larger and the original is kept as-is.
