How do I convert a PNG file to SRF?

Steps: 1) Upload your PNG image to the converter. 2) Choose SRF (Sun Raster) as the output format. 3) Set options such as background color for transparent areas and desired color depth (8-bit or 24-bit). 4) Click Convert and download the resulting SRF file. The entire process runs in your browser, so no extra software is required.

Why would I convert PNG to SRF?

PNG is a modern raster format with lossless compression and alpha channels, but it’s not recognized by many Unix workstation applications, legacy imaging pipelines, or industrial display systems. SRF (Sun Raster) is a lightweight format that those systems expect, and its simple RLE compression can be more efficient for flat-color images. Converting PNG to SRF ensures compatibility with older hardware and specialized technical tools.

What happens to transparency, color depth, and metadata when converting PNG to SRF?

SRF does not natively support alpha transparency, so the converter flattens transparent areas onto a solid background you specify. Truecolor PNGs are reduced to 24-bit RGB, and 48-bit or 16-bit-per-channel images are downsampled to 8 bits per channel. DPI metadata is retained in the SRF header where possible, but ICC color profiles are not preserved, so colors may shift depending on the target software.
