Compare what your browsers return.
Open this page in each profile, collect a sample, then load both files below. Every profile runs the same drawings. Pixels and image exports are compared byte for byte.
1. Collect this profile
Ready. Samples stay in this tab until you download them.
2. Compare two samples
Collect or choose two samples to begin.
RGBA is the raw API output. PNG compares encoded bytes, which can differ even when pixels match. Unavailable APIs never count as exact matches.
| Context / drawing | RGBA | Repeated RGBA | PNG data URL | PNG blob |
