About this tool

Use this free tool to convert images between formats directly in your browser. It is built for quick format swaps, favicons, and feeding files into tools that only accept certain types.

Supported sources: JPG, PNG, WEBP, HEIC, TIF, AVIF and BMP. Supported targets: JPG, JPEG, PNG, WEBP, AVIF, BMP, ICO and TIFF.

Browser-first conversion keeps common formats private and fast. Formats the browser cannot encode use a stateless API step with no permanent storage.

FAQ

Which formats can I convert between?

Sources: JPG, PNG, WEBP, HEIC, TIF, AVIF and BMP. Targets: JPG, JPEG, PNG, WEBP, AVIF, BMP, ICO and TIFF.

Are my files uploaded to a server?

Common conversions (to JPG, PNG, WEBP and BMP) run entirely in your browser. Formats the browser cannot encode — AVIF, TIFF and ICO, or sources like HEIC — use a stateless, in-memory server step with no permanent storage.

Can I create a favicon?

Yes. Choose ICO as the target and pick a size (16–256px) to generate an icon ready for a favicon or app shortcut.

What is the upload limit?

Files larger than 5MB are rejected early to keep performance and cost controlled.
