# WebP to SVG original experiments

2026-10-27. Original inputs generated with Pillow 12.3.0 / its bundled libwebp. Run `python generate-fixtures.py` with Pillow installed. Select a valid WebP on https://filepetal.com/webp-to-svg/, convert, save the offered SVG. Seven archived outputs were actually downloaded from the previous production page; the new preview does not change tracing. Parse SVG XML for dimensions/viewBox/paths/image/text/animation; render independently with sharp/librsvg for inspection. Invalid-header, truncated and 4097-wide controls are intentional diagnostics. No competitor conversion, cutter, font editor or physical-phone test. Encoder versions can change bytes. Hashes identify files, not quality.
