Every file is decoded locally, transformed ("© Nutter Tools" watermark), 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).

The watermark composites over the decoded pixels and re-encodes as PNG, a lossless re-encode of the marked pixels (the source's own losses carry through). Text uses the browser's system fonts. Embedded font rendering is not offered rather than approximated.
