Pattern

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

Go (RE2) code

goGo
package main

import (
	"fmt"
	"regexp"
)

func main() {
	re := regexp.MustCompile(`(?i)\.(jpe?g|png|gif|webp|svg|avif|bmp|ico|tiff?)$`)
	input := `photo.jpeg`
	for _, match := range re.FindAllString(input, -1) {
		fmt.Println(match)
	}
}

Uses `regexp.MustCompile` (panics on bad patterns at startup) and `FindAllString` for all matches.

How the pattern 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.

Examples

photo.jpeg

Matches

  • .jpeg
