Why convert TIFF to AVIF?

TIFF is the standard for professional imaging — used in print production, medical imaging, and archival storage. However, TIFF files are extremely large and cannot be displayed in web browsers. AVIF (AV1 Image File Format) delivers exceptional compression: files are 60–80% smaller than TIFF while maintaining excellent visual quality.

AVIF supports millions of colors, alpha transparency, HDR content, and both lossy and lossless compression. It is supported in Chrome 85+, Firefox 93+, Safari 16.4+, and Edge 121+. Converting TIFF to AVIF is essential when preparing professional images for web publishing.

Note that AVIF uses lossy compression by default — some pixel-level detail may differ from the original TIFF. For archival purposes, keep the original TIFF. For web use, AVIF provides the best file-size-to-quality ratio available today.

All processing happens locally in your browser — nothing is sent to any server. No registration, no limits, no watermarks.

How to convert TIFF to AVIF

Add your TIFF file
Drag and drop your TIFF image onto the converter area or click to browse your device. You can add multiple files at once for batch conversion.
Set the quality
The Set AVIF quality slider takes values from 60 to 95 percent, default 80. A lower value gives a lighter file, a higher one keeps more detail. Then click Convert.
Download AVIF
The Download button next to a file saves it on its own, and Download all packs all finished files into one ZIP archive. With a single finished file no archive is made, the file downloads directly.

How much does a file weigh before and after TIFF to AVIF conversion?

We ran 6 TIFF files through this converter at the default quality of 80 percent: an Unsplash landscape photo, a product photo, a leaf macro, a real screenshot with text, a logo with a transparent background, and a text page at scanner resolution. Weights are given exactly as the tool prints them in the queue: in kilobytes and megabytes of 1,024 bytes, with the same rounding. We took the measurement ourselves on 11 September 2026 in a Chromium browser; the result depends on the image content, so your file may come out differently.

Test file	Dimensions in pixels	TIFF	AVIF	Change
Landscape photo	1920 × 1280	6.61 MB	282.9 KB	23.9 times smaller
Product photo, uncompressed TIFF	1200 × 1200	4.12 MB	287.9 KB	14.7 times smaller
Leaf macro with fine detail	1600 × 2015	10.1 MB	1.17 MB	8.6 times smaller
Screenshot with text	1440 × 900	173.1 KB	80.3 KB	2.2 times smaller
Logo with a transparent background	1024 × 1024	374.7 KB	39.2 KB	9.6 times smaller
Text page, as from a scanner	1654 × 2339	408.6 KB	251.2 KB	39 percent smaller

Every one of our image format converters carries the same table with a real measurement. The tool shows the weight of your own file before and after conversion next to every row of the queue.

When should you convert TIFF to AVIF?

Website optimization
TIFF files are extremely large and cannot be displayed in browsers. Converting to AVIF reduces file size by 60–80% and creates web-ready images. Essential for publishing professional photos.
Every recipient has to open the file
Email clients and older graphics programs do not display AVIF files yet. For a photo going by email or into such a program use the TIFF to JPG converter.
Online shop
Product galleries and thumbnails in AVIF load faster, and the transparent background of a packshot stays in the file.
The file is still going back for editing
Every further save in a lossy format removes some detail. When the image is still going into an editor, keep the original TIFF file and convert only the final version.

What makes this TIFF to AVIF converter different?

Complete privacy
Your TIFF files are processed entirely in your browser. Nothing is uploaded to any server – your images stay on your device at all times.
Many files at once
Add any number of TIFF files, each up to 100 MB. The converter processes them one by one and shows the status of each.
Quality slider
The Set AVIF quality slider from 60 to 95 percent, default 80. Next to every file you see the size before and after conversion, and under the list the total for the whole queue.
Download in one archive
The Download all button packs all finished files into one ZIP archive, so you do not have to approve a dozen downloads one after another.

Quality settings – what to choose when converting TIFF to AVIF?

The quality slider lets you set a value from 60% to 95%. Higher values mean better image quality but larger file sizes.

80% (default) – a good balance for most use cases: web publishing, blogs, articles. The visual difference compared to the original is virtually unnoticeable.
85–90% – for high-quality product photography, portfolios, and galleries where every detail matters.
60–70% – when minimizing file size is the priority, e.g. thumbnails or preview images.

Frequently asked questions about TIFF to AVIF conversion

Is converting TIFF to AVIF free?

Yes, this TIFF to AVIF converter is completely free with no limits. You can convert as many files as you need without registration or watermarks.

Does the converter upload my files to a server?

No. All processing happens locally in your browser using JavaScript and Canvas API. Your files never leave your device, ensuring complete privacy and security.

Will I lose quality when converting TIFF to AVIF?

Yes, AVIF from this converter is saved lossy, at the quality set by the Set AVIF quality slider (default 80 percent). At that value the difference is invisible on screen, while at 60 percent fine detail starts to blur. The encoder has no lossless mode.

Can I convert multiple TIFF files at once?

Yes, the converter supports batch conversion. You can add multiple TIFF files and convert them all to AVIF simultaneously. Use the batch download option to save all converted files at once.

Do all browsers support AVIF?

Yes, in current versions: Chrome from 85, Firefox from 93, Safari from 16.1 and Edge from 121. An older browser shows nothing in place of an AVIF image, so a page that has to serve them keeps a JPG or WebP fallback.

What is the maximum file size?

Each file may be up to 100 MB; a larger one stops on the list with a message that it is too large. The number of files in the queue is not limited, and large images take longer because the browser decodes them fully into memory.

Does the converter work on mobile devices?

Yes, the converter works on any device with a modern web browser, including smartphones and tablets. The interface adapts to your screen size for a comfortable experience on any device.

How do I download all files at once?

The Download all button packs the finished files into one ZIP archive named tiff-avif.zip. With a single finished file no archive is made and the file downloads directly.
