Image Compressor

Choose 100 KB as the target size. If the image cannot get that small, pick a smaller maximum width or height, such as 1000 px.

JPG and WebP images lose a little: the tool keeps the highest quality that still fits your target size, and the comparison slider shows the result next to the original. PNG images stay lossless, so only a smaller maximum width or height makes them smaller.

Under Compress by, choose Quality to set a fixed quality from 30 to 95 % instead of a target size. A lower value makes smaller files. The size is then whatever comes out, so check it in the list.

PNG is lossless. Choose JPG or WebP as the output format to make it much smaller (transparent areas become white in JPG).

When two or more images are done, use Download all (ZIP) for one ZIP file, or Download all separately for one file after another. On phones that can share files, Save / Share all opens the share menu, for example to save to Photos.

Yes. The compressed images are written fresh in your browser, without location or camera info. If an image is already so small that it cannot get smaller, the original is kept and the result says that its location info could not be removed.

No. Everything happens in your browser, so your images never leave your device.

WebP gives the smallest files, but not every website accepts it. JPG works everywhere; transparent areas become white. PNG is lossless, so PNG images only get much smaller when you choose JPG or WebP as the output format. If your browser cannot write WebP, choose JPG.

By default the longest side is limited to 2000 px, which makes files much smaller. Images are never enlarged. Under Maximum width or height, choose Keep original size to keep every pixel (the file will be bigger), or 1500 or 1000 px for smaller files.
