How to compress an image

Select an image from your device.
Adjust JPEG quality. Lower quality often creates a smaller file, but the result depends on the image and may not always be smaller.
Select Compress image, review the preview and file sizes, then download the result.

Example: If a photo is too large to attach, try a lower quality setting and compare the new size before downloading. Compression results depend on the image and setting; JPEG compression can reduce image detail.

Your image is processed in this browser and is not uploaded to a processing server. This tool outputs JPEG, which does not preserve transparent backgrounds.
