How to use
Choose an image, enter the target width or height, keep aspect ratio on when appropriate, select the output format, then process and download.
Privacy
The selected image stays in browser memory and is not uploaded to our server.
Limitations
The browser tool rejects very large files or pixel dimensions to reduce memory pressure. Animated images are exported as a single frame.
Example
