Convert PNG to ITHMB

Looking for PNG to ITHMB? Here's why ITHMB isn't an output option — and the modern formats to use.

We don't create ITHMB files — it's a legacy format that's effectively read-only. Here's what to convert to instead.

Why PNG to ITHMB isn't offered

ITHMB is legacy and read-only here

ITHMB is an older raster format. It can usually be opened and converted from, but it's long obsolete, so there's no modern encoder to create new ITHMB files.

Convert to a current format

For a file that opens everywhere, convert your PNG to JPG, TIFF or WEBP instead.
