About this tool
Phone cameras produce photos of 3 to 8 MB, far larger than most upload forms allow. Lowering the quality setting slightly and capping the dimensions usually cuts the size by more than half with no visible difference.
Compression happens with your browser's built-in image encoder. WebP usually gives the smallest files and is supported by all modern browsers.
Frequently asked questions
How much smaller will my images get?
Typical phone photos shrink by 50 to 80% at quality 70 to 80, especially when you also limit the size to 1920 or 2560 pixels.
Which format should I use?
JPG works everywhere. WebP is smaller at the same quality and works on all modern browsers and websites. PNG is lossless and best for screenshots with text.
Will transparent PNGs stay transparent?
Yes with WebP or PNG output. JPG does not support transparency, so transparent areas become white.
Is photo metadata removed?
Yes. Compressing re-draws the image, which removes EXIF metadata such as camera details and GPS location.
Are my photos uploaded?
No. Everything happens on your device.
