Every row below is a byte-exact 1×1 image constructed in this page and handed to the browser's own decoder. Run it to see what THIS browser does, the same page on another browser can honestly answer differently.

• Every matrix row is measured: the embedded fixtures are byte-exact 1×1 images whose magic bytes and container-stated dimensions are pinned by tests, decoded through the same native Image.decode path on demand. A canned "all browsers support X" table would be a claim; this is a result.
• AVIF and JPEG XL ship no embedded probe. No byte-exact sample is constructible here without vendoring binary blobs, and a wrong fixture would read as "unsupported" everywhere. The page says so; drop your own file to test.
• Your file is identified from magic bytes, not the extension: a mismatch is named ("the bytes win"), the declared type shown alongside for comparison.
• Decode timings are informational (one decimal, this machine, this moment), never presented as a benchmark.
