Is converting PNG to ICO free?

Yes. No account, watermark, or daily limit.

Are my images uploaded?

No. Decoding and encoding run in this browser tab; the files never reach Omnipus servers.

Convert PNG (Portable Network Graphics) files to ICO (Windows icon / favicon) without uploading them.

Favicons and Windows shortcuts need ICO. One .ico file can hold several sizes so browsers and the OS pick the sharpest one.

Transparency is kept.

The .ico contains 16, 32, 48, 64, 128, and 256 px sizes. Non-square images are centered without stretching.

Metadata such as EXIF and GPS location is not copied, because the image is redrawn on a canvas.
