Free online TIFF to AVIF converter

What the TIFF format is

TIFF (Tagged Image File Format) is a raster-image container used for scanned documents, print production, publishing, photography, geographic imagery, scientific imaging, and archival masters. TIFF can store uncompressed pixels or use lossless compression, high bit depths, alpha channels, embedded ICC color profiles, and multiple pages or frames.

Scanners, Adobe Photoshop, Adobe Lightroom, Affinity Photo, GIMP, desktop-publishing systems, document-management software, and scientific cameras commonly create .tif and .tiff files. TIFF is intended for preserving image data and supporting later editing, not for minimizing web download size.

What the AVIF format is

AVIF (AV1 Image File Format) stores still images using the AV1 image codec in an ISO Base Media File Format container. It supports lossy and lossless encoding, transparency, HDR, wide-gamut color, high bit depths, and image sequences.

AVIF can produce substantially smaller files than TIFF and often smaller files than JPEG or PNG at a similar visual quality. This makes it suitable for websites, applications, APIs, and storage systems that support the format. Current Chrome, Edge, Firefox, Safari, Android, and many image applications support AVIF, but older browsers, operating systems, desktop programs, and publishing systems may not.

Convert TIFF to AVIF online

You can convert the file for free on 101convert.com without installing software:

1. Open the TIFF-to-AVIF converter on 101convert.com.
2. Select or drag in the .tif or .tiff file.
3. Start the conversion and wait for processing to finish.
4. Download the resulting .avif file and test it in the program or website that will receive it.

Use a local desktop application instead for confidential scans, medical images, unreleased photographs, or files whose metadata must not be uploaded.

Convert TIFF to AVIF with ImageMagick

ImageMagick is suitable for local conversion, scripting, and batch processing, provided that its installation has AVIF write support. Check the available formats:

magick identify -list format | grep -i AVIF

On Windows, run magick identify -list format without grep and inspect the format list. An AVIF entry with write capability is required; ImageMagick delegates AVIF encoding to an installed AV1/HEIF library.

Convert one TIFF with a lossy quality setting:

magick input.tif -quality 80 output.avif

Quality values around 50–75 usually produce smaller web files, while 90–95 retains more fine detail. The exact result depends on the ImageMagick build and AVIF delegate, so inspect the output at its intended display size rather than relying on the number alone.

To convert only the first page of a multipage TIFF, use:

magick input.tif[0] -quality 80 output.avif

To create separate AVIF files from the pages, use:

magick input.tif -scene 0 -quality 80 page-%02d.avif

Use -strip only when EXIF, XMP, ICC profiles, comments, and other metadata should be removed:

magick input.tif -strip -quality 80 output.avif

For CMYK or color-critical TIFF files, preserve the embedded source profile and perform a controlled conversion to the intended RGB output profile. A simple colorspace switch can produce incorrect colors when the source profile is missing or misidentified.

Use a desktop image editor

Current versions of GIMP and other image editors with AVIF export can open the TIFF, flatten or otherwise prepare the image, then use File → Export as and choose .avif. Set the encoder quality or lossless option if available, then inspect the exported dimensions, colors, transparency, and file size. AVIF export support varies by application version and operating-system build.

Quality and compatibility limits

TIFF compression and AVIF encoding are separate choices. A losslessly compressed TIFF can lose texture, text edges, film grain, or subtle gradients when exported as lossy AVIF. Keep the original TIFF as the editing or archival master and use AVIF as a delivery copy.

AVIF supports lossless encoding, but the conversion software must expose and correctly use that mode. Lossless AVIF can be much larger than lossy AVIF and still cannot preserve TIFF-specific structures such as editing layers, unusual tags, or a complex multipage document as editable data.

Most TIFF pages convert to separate AVIF images or a format-specific image sequence. If every page must remain independently addressable, separate output files are safer than relying on sequence support. Layered TIFF content is generally rendered into a flat image during export.

Before publishing, verify the output dimensions, RGB or wide-gamut color handling, ICC profile, alpha channel, metadata, and display in the target browser or application. Provide a JPEG or PNG fallback when AVIF support has not been confirmed.
