What is Resize to File Size?

Resize to file size automatically shrinks a photo to meet an upload limit such as 'under 200KB'. It lowers quality step by step first, then reduces resolution if needed, to find the best quality under the target size.

For output, choose JPG for the best compatibility or WebP for a smaller file. Use it when uploading photos with size limits, such as job applications, government forms or exam registrations.

How to use

Upload the photos you want to shrink.
Set the target size (KB) and output format.
Click "Resize to File Size" and download the photo, now under your target.
