How it works
Every file is decoded locally, transformed (HQX 2× pixel-art scale), and re-encoded as PNG, output signature and dimensions are verified before a row counts as done. Animated inputs keep their first frame only (flagged on the row). HQX reads edges in YUV space and interpolates only inside a shape, so sprites stay sharp where a smoothing resampler would blur them. Sources up to 4096px per side and 4,000,000 pixels. Larger art is out of this algorithm's league. Output is PNG with dimensions verified: no quality knob, nothing recompressed twice.
