Image Compressor
Shrink photos for websites, email and upload forms. Pick a quality, compress up to 30 images at once and see exactly how much you saved.
How to compress images
Choose your photos, leave quality around 70% (it looks the same to the eye but is often 60–90% smaller), and tap Compress images. Lower the max size to 1920 px for websites and email; phone photos are often 4000 px wide, which is far more than any screen needs.
JPG works everywhere. WebP is about 25–35% smaller again and is supported by all modern browsers and most websites. Transparent PNGs get a white background when saved as JPG.
Need an exact file size, like under 50 KB for a form? Use Resize image to KB.

Phone photos usually shrink 70–90% at 70% quality and 1920 px, with no difference you can see on a screen.
What's the best quality setting?
60–80% is the sweet spot for photos. Go lower only if you need a very small file.
Are my images uploaded?
