Why use Compress Images?
Real compression control
Most compressors give you a single slider. Here you control quality, maximum resolution, output format and even a target file size — globally or per image.
See the savings first
The estimated output size updates per image and in total as you change settings, so you find the sweet spot before you download.
100% private
Compression runs locally in your browser. Your images are never uploaded, stored or seen by anyone.
Works on any device
No install and no account. It runs in any modern browser on Windows, macOS, Linux, Android or iPhone.
One tool for every format
Drop in a mix of JPG, PNG, WebP, GIF, BMP, AVIF, SVG or iPhone HEIC photos and compress them all at once. HEIC is decoded automatically. You set a global default, then optionally override any single image — handy when one picture needs to stay sharp while the rest are squeezed.
Quality, resolution or a hard size limit
Lower the quality to drop detail your eye barely notices, reduce the maximum resolution to cut the pixel count, or set a target size in megabytes when you have a strict limit to hit. The estimated output size updates per image and in total, so you see the savings before you download.
Frequently asked questions
Which image formats can I compress?
JPG/JPEG, PNG, WebP, GIF, BMP, AVIF and SVG are handled natively, and iPhone HEIC/HEIF photos are decoded automatically. You can mix formats in one batch.
Are my images uploaded to a server?
No. Decoding, any editing, and the conversion all run entirely in your browser. Your files never leave your device, so it even works offline once the page has loaded.
Can I convert several images at once?
Yes. Add as many as you like — a single image downloads directly, and multiple images are bundled into one .zip so you get everything in a single click.
