How to Convert AVIF to TIFF in Your Browser
Converting an AVIF image to TIFF produces an uncompressed 8-bit RGBA TIFF suited to print production, scanning, and archival master copies. This guide covers the steps and what to know about transparency and file size.

Step-by-step conversion
- Open /tools/avif-to-tiff.
- Choose an AVIF file — the content is validated before conversion, not just the filename or extension.
- Select Convert & download.
- Save the .tiff file from your browser downloads.
Transparency and file size
Output is uncompressed 8-bit RGBA, so an alpha channel from the source is preserved. Because the file is uncompressed, it can be several times larger than the source.
Source-specific behavior
Animated AVIF files convert as a still image — only the first decodable frame is used, and AVIF decoding itself depends on your browser.
Privacy
Conversion runs locally in your browser. The file is not uploaded to Looty Tools servers for this workflow.
Convert AVIF to TIFF FAQ
- Why would I need TIFF instead of AVIF?
- Print shops, scanning pipelines, and archival workflows often specifically require TIFF as the master format.
- Does every browser support AVIF?
- No. AVIF decoding depends on your browser. Unsupported browsers show a clear decode error instead of a mislabeled download.
- Does TIFF output keep transparency?
- Output is uncompressed 8-bit RGBA, so an alpha channel from the source is preserved. Because the file is uncompressed, it can be several times larger than the source.
- Are my files uploaded?
- No. Conversion runs locally in your browser and does not upload your file to Looty Tools servers.
- What is validated before conversion?
- The file must actually be an AVIF — the tool checks the ISO-BMFF ftyp brand, not just the filename or extension, before decoding.
