Convert BMP to RLE

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

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

Why BMP to RLE isn't offered

1

RLE is legacy and read-only here

RLE (Utah RLE) is an old run-length-encoded raster format. It can usually be opened and converted from, but it's long obsolete, so there's no modern encoder to create new RLE files.

Convert to a current format

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