FAQ

When should I use PNG over JPG?

PNG is a lossless format and supports alpha channel (transparency). Use it when you need maximum conversion quality from your HEIC or when the image contains complex graphs or text.

Does converting to PNG increase the filesize?

Yes, it is common. Uncompressed PNG files are often far larger than heavily compressed HEICs. You can use MuteForge to process these massive files with no file size limits.

Are my files uploaded?

No. Not a single byte leaves your smartphone or PC.
