Image converters

Format conversion is the most common reason people reach for an online image tool, usually because something refuses to open a file. A WebP saved from a website, an AVIF from a fast-loading page, a HEIC from an iPhone — all perfectly valid images that some piece of software will not touch.

Every converter here uses the decoder and encoder already built into your browser. That makes conversion instant and keeps the file on your machine. Where a format genuinely cannot be decoded locally — HEIC in most browsers — KaiConvert says so rather than quietly uploading it.
