Frequently Asked Questions
Does resizing keep the image quality?
The tool uses browser canvas rendering, so quality is generally good, but very large downscales will still reduce detail as expected from any resize operation.
Which formats are supported?
You can upload common image types and export the resized result as PNG, JPEG, or WebP.
Can I keep the original proportions?
Yes. Leave the aspect ratio lock enabled and changing one dimension will automatically update the other.
Is my image uploaded to a server?
No. The resizing happens inside your browser, so the file stays on your device.
