FAQ

Does this tool upload my images?
No. Resizing runs locally in your browser. Files are not uploaded to our server.

Why is the downloaded file size different?
Different formats (PNG/JPG/WebP) and quality settings affect file size. Try WebP or lower quality for smaller files.

Can I resize without changing aspect ratio?
Turn off “Keep aspect ratio” to set width and height independently.
