TIFF to AVIF Converter

To convert TIFF to AVIF, add your TIFF files, choose AVIF, adjust the quality (60% by default) and press Convert. Large TIFF scans and photos become very small AVIF images for modern browsers, although encoding takes a bit longer. Each file is uploaded to our servers over a secure connection, read there and deleted within 30 minutes at the latest. Multi-page TIFFs give their first page.

  • Free, no sign-up
  • Uploaded securely, deleted within 30 minutes
  • Up to 50 MB per file

For multi-page TIFF files only the first page is converted.

Your file is uploaded to our servers over a secure (HTTPS) connection, converted there and permanently deleted within 30 minutes at the latest. Files are converted one after another.

How to convert TIFF to AVIF

  1. Add your TIFF files

    Drag the files onto the upload area or browse for them; you can add several files and they are converted one after another.

  2. Keep AVIF as the output

    AVIF is already selected. The quality slider starts at a default that suits the format (JPG 90%, WebP 80%, AVIF 60%); lower it if you want an even smaller file.

  3. Convert and download

    Press “Convert”. Each file is uploaded to our servers, converted and deleted within 30 minutes at the latest; download the results one by one or as a ZIP.

What is preserved?

Kept

  • The image resolution (pixel dimensions)
  • The correct photo orientation (EXIF orientation is applied)
  • Colors (adapted to sRGB)
  • Transparency (alpha channel)

Changed

  • AVIF is a lossy format: lower quality means a smaller file but less fine detail
  • The lossless source is recompressed at the quality you choose, so pixel values are no longer identical

Not carried over

  • EXIF, location and camera data: left out of the output for privacy
  • Pages after the first in a multi-page TIFF: only the first page is converted

When to use it

Lighter high-resolution galleries

Detailed TIFF photographs can be shown on a website as AVIF with a fraction of the bandwidth, which matters for large images on mobile connections.

Long-term viewing copies

Keep the TIFF as your master and store an AVIF viewing copy next to it, so you can browse a large archive quickly without opening huge files.

Limitations to know

  • Up to 50 MB and about 100 megapixels per file.
  • The file is uploaded to our servers and deleted within 30 minutes at the latest; several files are converted one after another.

About the formats

What is TIFF?

TIFF is a high-quality image format used for scans, professional photography and printing. It typically stores pixels without lossy compression and can hold high color depth and several pages in one file, so files are very large. Web browsers do not display TIFF, so it is converted to JPG or PNG for sharing and publishing.

What is AVIF?

AVIF is a modern image format based on the AV1 video codec. It delivers very small files at high visual quality, supports transparency, HDR and animation, and is among the most efficient formats for the web. Encoding is slower than for other formats, and some older software cannot open AVIF yet.

Frequently asked questions

Should AVIF replace my TIFF masters?

No. AVIF is lossy and meant for viewing and sharing; keep the original TIFF files as your archive and editing source.

Does 16-bit TIFF color survive in AVIF?

The image is converted to standard color depth on the way, so extra precision used for heavy editing is not preserved. For viewing on screen the difference is not visible.

Can older software open the AVIF?

Current browsers can, but many older image viewers and office programs cannot. If recipients use older software, TIFF to JPG is safer.

Is converting TIFF to AVIF free?

Yes, completely free. There is no account, subscription or watermark; just add your files and convert them.

Are my files uploaded anywhere?

Yes. This conversion runs on our servers, so your file is uploaded over an encrypted (HTTPS) connection, converted there and permanently deleted within 30 minutes at the latest. It is stored under a random code instead of its name, and processing is fully automated. EXIF and location data are not added to the output.
