0 B uploaded — this page has not sent your files to any server?

Private by design — this tool never uploads your files anywhere. All conversion happens inside your browser, and the result is saved straight to your device.How this differs from upload-based sites — most converter sites upload your photo to a server, process it there, and promise to delete it after a while. Until that happens, your photo is sitting on someone else's server. imgmoa has no upload step at all. The more sensitive the photo — a scanned ID, a photographed contract, pictures of your kids — the more that difference matters.

WebP to AVIF — FAQ

Why convert WebP to AVIF?

WebP is the modern web format with the smallest file size, while AVIF is a next-generation high-compression format. Convert when an app or website doesn't accept WebP, or to fix size and compatibility issues.

Why does AVIF conversion take so long?

AVIF achieves the highest compression, which makes encoding computationally heavy. Large photos can take tens of seconds — it all runs in your browser, so keep the tab open.

Where can AVIF files be opened?

All modern browsers — Chrome, Edge, Firefox and Safari 16.4+ — support AVIF. Older apps may not, so choose JPG or WebP if compatibility matters.

Is it free? Are my files safe?

Completely free with no limits. Your files are processed inside your browser and never uploaded to any server.
