JSSupported

JavaScript / ECMAScript

Browser-native RegExp. Default if you don't pick.

PYSupported

Python (re)

CPython stdlib `re`. Unicode-aware `\w` and `\d` by default.

GOSupported

Go (RE2)

Linear-time matching. No backreferences or lookarounds.

Pattern

regexengine-agnostic
\.(jpe?g|png|gif|webp|svg|avif|bmp|ico|tiff?)$   (flags: i)

Raw source: \.(jpe?g|png|gif|webp|svg|avif|bmp|ico|tiff?)$

How it works

\. matches the literal dot. The alternation group covers all common web and raster image extensions. jpe?g covers both jpg and jpeg. tiff? covers tif and tiff. The i flag makes matching case-insensitive so .PNG and .JPG also match.
