Frequently asked questions

Can I resize an image to any size?

Yes. You can enter a custom width and height up to 8000 × 8000 pixels.

Does this tool support PNG, JPG and WebP?

Yes. You can upload PNG, JPG, JPEG, WebP, GIF, BMP and SVG images and export the result as PNG, JPG or WebP.

Can I maintain the original aspect ratio?

Yes. Enable Maintain aspect ratio and changing one dimension will automatically calculate the other dimension.

Can I convert SVG images?

Yes, supported SVG files can be loaded and rasterized into PNG, JPG or WebP output.

A GIF can be loaded as an image, but browser Canvas conversion processes the displayed GIF frame rather than preserving animation.
