Turning an AVIF into a PNG
Drop an AVIF into the upload area or tap to browse for one. The browser decodes the AVIF with its own support and writes it back as a lossless PNG. Both halves are native, so there is no module to fetch and no pause to warm up. Most photos clear in under a second. When it finishes, the readout sets the original AVIF size next to the fresh PNG size, and that PNG will plainly be the bigger of the two. Hit Download to keep it under the original base name with a .png extension. From that moment the file behaves like any ordinary PNG and opens in whatever app you point at it.
