TIFF to AVIF Converter
Convert TIFF images to AVIF directly in your browser — a modern format with strong compression for web delivery, encoded with adjustable quality.
TIFF to AVIF processes files locally in your browser.
What TIFF to AVIF conversion does
Convert a TIFF image to AVIF directly in your browser, with adjustable quality. Encoding uses the browser canvas API and is verified as a real image/avif download before it reaches your downloads folder — a way to make a large, often uncompressed archival TIFF page genuinely web-deliverable.
How to convert TIFF to AVIF
- Choose a TIFF or TIF file.
- Adjust AVIF quality if needed.
- Select Convert & download.
- Save the .avif file from your browser downloads.
Why use this conversion
TIFF pages, especially scans and archival images, are frequently large and effectively uncompressed. AVIF's modern compression can shrink that same page dramatically for sites that already serve modern image formats.
Transparency and output quality
Transparent pixels from the source TIFF page stay transparent when the browser AVIF encoder supports alpha. This tool does not flatten onto an arbitrary background before encoding. The quality slider defaults to 90%. Because TIFF pages (as decoded here) are typically large and uncompressed, AVIF conversion usually produces a substantial size reduction — though lower quality values can introduce visible compression artifacts, and a smaller file is not guaranteed for every source image.
Privacy and local processing
- Processing occurs locally in the browser.
- Files are not uploaded to Looty Tools for conversion.
- Converted files remain on your device.
Limits and known issues
- Input: TIFF (.tif, .tiff) only, up to 25.0 MB and 8,192 px per side.
- Canvas AVIF encoding is Chromium-first today. Unsupported browsers show a clear error instead of a mislabeled download, and usage is not recorded for a failed conversion.
- Multi-page TIFFs lose everything past page one in this conversion — only the first page is decoded and encoded to AVIF.
- Metadata is not preserved in the downloaded file.

TIFF to AVIF FAQ
- Why convert TIFF to AVIF?
- TIFF pages — scans and archival images especially — are often large and effectively uncompressed. AVIF's modern compression can shrink that same page dramatically, making it practical to serve on the web.
- Can every browser create AVIF?
- No. Canvas AVIF encoding is Chromium-first today. The tool probes encoding support and verifies the download is image/avif — unsupported browsers get a clear error instead of a mislabeled download.
- Does AVIF output keep transparency?
- Transparent pixels from the source TIFF page stay transparent when the browser AVIF encoder supports alpha. This tool does not flatten onto an arbitrary background.
- Does this convert every page of a multi-page TIFF?
- No. Only page one of the source TIFF reaches the AVIF encoder — additional pages in a multi-page scan are not converted.
- 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 a TIFF — the tool checks the byte-order header (little-endian "II*" or big-endian "MM*"), not just the filename or extension, before decoding.
