Image format conversion swaps a file's encoding — JPG to PNG to add transparency, PNG to WebP to shrink it, HEIC to JPG so it actually opens on Windows. The ToolEdge Image Format Converter handles the four formats that account for >99% of real-world images: **PNG, JPG, WebP, and AVIF**. The conversion runs entirely in your browser via the Canvas API; nothing is uploaded.
WebP and AVIF deserve a brief defense: they're modern formats designed for the web that produce **significantly smaller files** than JPG and PNG at the same visible quality. WebP is supported by every modern browser (Chrome, Firefox, Safari, Edge) and almost every modern app. AVIF is newer, even smaller, but support is still rolling out — safe for web pages, less safe for old desktop software. When in doubt, WebP is the safer modern choice.
