Review screenshot changes locally.
Pair supplied baseline and current images, measure decoded RGBA differences, mark ignore regions and export one reviewable evidence pack.
Supply both sides
Select equal counts. Pairing and dimensions are confirmed before any pixels are decoded.

Selected image content and filenames are processed in this page and are not sent to a WebRynx application endpoint. Originals are read and hashed, not modified and not included in the evidence ZIP.
Manual comparison board
Measurements describe decoded pixels. Only your expected, bug or review choice classifies a change.
Contact board
Each row shows baseline, current and heatmap. Gray checker regions were ignored.
Human decisions
Every pair starts in review. Notes and classifications are saved in the ZIP.
- No page, URL, CI job, browser matrix or physical device is captured.
- Canvas measures bytes after this browser decodes color profiles and compressed pixels.
- Ignore rectangles use raw image pixels and never resize either side.
- A zero pixel difference is still not an automatic semantic approval.
