What file formats are supported?

The resizer accepts PNG, JPEG, GIF, WebP, and SVG files. All resizing is done using the Canvas API and output is provided as PNG files.

Does resizing reduce quality?

Downscaling high-resolution icons to smaller sizes is generally lossless for most intents. The Canvas API uses bilinear interpolation, which produces smooth results for icon art.

Is my file uploaded anywhere?

No. The resizing happens entirely in your browser using the Canvas API. Your files never leave your device.
