About

Pixel Overlay places a design image on a normal http(s) page so you can compare layout to a mockup. Chrome://, the Web Store, and other restricted pages are skipped. Free tools stay in this browser — no ExtHub account. Local files never leave the device; only an optional http(s) image URL can be stored with a recipe. Turn Show overlay on, or Pause all. Opacity, lock position, Invert, and blend chips Normal and Multiply. Load from an image URL or a PNG/JPEG/GIF/WebP file up to 4 MB. Unlock to nudge with arrows (Shift = 10 px). Esc hides without wiping the image. Local recipes (host and overlay metrics) and an action log (host and tool — not page HTML, not image pixels). Up to 12 recipes and 20 log rows locally. Pro syncs recipes, overlay prefs, and the log to ExtHub (hosts and overlay metrics only — not pixels, not HTML). Extra blends Difference and Screen, scale 50–200%, and an 8/16 px grid. JSON export/import (data URLs stripped), and higher caps (50 recipes / 80 log rows). Search and CSV/JSON export are on the ExtHub My data page. Unsigned installs still send a compact connectivity ping.
