Static SVG. Keeps displayed pixel colours and transparency. Matching blocks are merged. Best for small pixel art; up to 4 million pixels.

Use View on a frame to choose it. Sheet SVG uses the columns and spacing above.

Help & credits

GIF mode reads animated GIFs. Image mode reads still PNG/JPEG/WebP images (animated WebP uses its first image). Sheet slicing runs left to right, then down. GIF timing is rounded to 10 ms with a 20 ms minimum. Imported timing is kept; Loop is on by default. Output is limited to 2048 pixels per side and 20 million total frame pixels. Sheet output: up to 8192 pixels per side / 16 megapixels. Files are not saved between visits.
