How compression works here
Your images are processed in your browser and are not uploaded to our server. JPEG and WebP use lossy compression controlled by the quality slider; 70–85 is usually indistinguishable at normal viewing size. PNG is lossless, so re-saving one rarely saves much: to shrink a PNG photo, convert it to WebP or JPEG. Resizing to the size you actually display usually saves the most. If a result would be larger than the original, the tool tells you to keep the original.
Re-encoding removes most metadata, such as camera details and GPS location.
Frequently asked questions
Are my images uploaded?
No. Compression happens on your device, so it also works for private images.
Why did my PNG barely shrink?
PNG is lossless. Choose WebP or JPEG for photos, or reduce the dimensions.
Is there a limit?
Up to 25 MB per image and 100 megapixels, depending on your device’s memory.
