FAQ

Will every output image be exactly the size I typed?

Only if you untick 'Maintain aspect ratio'. With it ticked, each image is scaled down or up to fit inside the box, so a landscape photo in an 800x600 box may come out 800x533. Different images can therefore end up with different dimensions.

Does unticking the aspect ratio crop my images?

No. It stretches them to the exact width and height, which distorts the picture if the ratio is different. This tool has no crop or padding mode. For exact-size output without distortion, use the single-file Canvas Resize tool, which pads instead.

How do I get my files back?

If you process one image you get that image. If you process two or more, the results are bundled into one ZIP, and each file keeps its original name with the output extension.

Are my images uploaded anywhere?

No. The resizing is done by your browser with a canvas element, and the files stay on your device. A very large batch of high-resolution photos can be slow or memory-hungry, so split it if the tab struggles.
