What Is the AVIF Format?

AVIF (AV1 Image File Format) is a modern image format developed by the Alliance for Open Media. It uses the AV1 video codec for still image compression and delivers remarkable file size reductions compared to older formats — typically 50% smaller than JPG and 30–40% smaller than WebP at equivalent visual quality.

AVIF was ratified in 2019 and gained major browser support by 2021–2022. Today, it is widely used for web delivery, web storage, and as a default output format from image processing pipelines that prioritize file size. It supports both lossy and lossless compression, alpha channel transparency, wide color gamut, and HDR.

Despite its impressive compression efficiency, AVIF has a significant limitation in professional workflows: it is not natively supported by most desktop image editors, print production software, or archival systems. This is where TIFF conversion becomes necessary.

What Is the TIFF Format?

TIFF (Tagged Image File Format) was developed by Aldus Corporation (later acquired by Adobe) in 1986 and has remained the gold standard for professional image storage ever since. Unlike web-optimized formats such as AVIF, TIFF is designed for maximum fidelity, not minimum file size.

TIFF stores pixel data with lossless compression (LZW or PackBits) or completely uncompressed. A TIFF file can store multiple layers, support 16-bit or 32-bit per channel color depth, embed CMYK color profiles for print, and contain alpha channel transparency — all in a single file. These properties make TIFF the preferred format for print production, medical imaging, publishing, and long-term digital archiving.

When Should You Convert AVIF to TIFF?

The decision to convert AVIF to TIFF almost always comes down to one of four professional requirements:

• Print production. Commercial printers, RIP systems, and preflight tools expect TIFF or PDF input. If you have images stored or delivered as AVIF and need to send them to a print shop, converting to TIFF is the correct step. TIFF preserves color accuracy and is the format that CMYK print workflows understand.
• Non-destructive editing. Adobe Photoshop, Lightroom, Affinity Photo, and GIMP all support TIFF natively with full layer and adjustment layer preservation. Opening an AVIF in Photoshop is possible but discards lossless data that TIFF would retain for later editing passes.
• Long-term archiving. AVIF depends on AV1 codec support remaining available in future software. TIFF is a decades-old open format with no codec dependency — it will still be readable in 30 years. Professional archivists use TIFF precisely because it does not rely on a proprietary or modern compression algorithm.
• Software compatibility. Many scientific, medical, and GIS software applications support TIFF natively but have no AVIF support. Converting to TIFF is the compatibility bridge in those environments.

AVIF vs TIFF: Format Comparison

Does AVIF to TIFF Conversion Lose Quality?

This is the most common concern for photographers and designers making this conversion — and the answer requires a small technical clarification. TIFF itself is a lossless output format: once the AVIF pixel data is decoded and written to TIFF, those pixels are stored exactly as they are. No additional compression or quality degradation is introduced by the TIFF encoding step.

However, if your source AVIF was encoded as a lossy AVIF (the default for most web AVIF files), the lossy compression artifacts were already baked into the pixel data before you started. Converting a lossy AVIF to TIFF does not undo that original quality loss — it simply freezes the current state of the pixels in a lossless container. This is still the correct approach: you are getting the best possible TIFF from the data that exists in the AVIF file.

If your AVIF was encoded as a lossless AVIF, the TIFF output is pixel-for-pixel identical to the original source, which is ideal for archival workflows.

Understanding the File Size Difference

One aspect of AVIF to TIFF conversion that surprises many users is the dramatic file size increase. A 500 KB AVIF file may produce a 20–50 MB TIFF. This is not a problem — it is the expected and correct behavior of a lossless format.

AVIF uses the AV1 codec to achieve extraordinary compression. A 12-megapixel image contains roughly 36 MB of raw pixel data (at 8-bit RGB). AVIF compresses this to perhaps 1–3 MB for lossy output. TIFF stores those same 36 MB of pixels with only minimal LZW compression, resulting in a file of 30–60 MB depending on image content.

When the large TIFF file size is a concern for delivery rather than archiving, consider keeping your AVIF for web use and reserving TIFF only for print and archival copies.

How Browser-Based AVIF to TIFF Conversion Works

The AVIF to TIFF converter on this site uses two technologies to perform the conversion entirely in your browser:

• Native browser AVIF decoding. Modern browsers (Chrome 85+, Firefox 93+, Safari 16+, Edge 121+) support AVIF natively. The JavaScript createImageBitmap() API decodes the AVIF file into raw pixel data without any external library. This is the same decoder your browser uses to display AVIF images on websites.
• UTIF.js for TIFF encoding. The decoded pixel data (as a Uint8ClampedArray of RGBA values) is passed to UTIF.js, a pure JavaScript TIFF encoder. UTIF generates a valid, compliant TIFF binary blob in memory.

Both steps happen entirely in your browser. Your AVIF files are never sent to a server. From the moment you drop a file onto the page to the moment you download the TIFF, everything runs locally in your browser's JavaScript engine.

TIFF in Print Workflows

For those who are converting AVIF to TIFF specifically for print production, a few additional considerations apply. Most print service providers and RIP systems expect TIFF files in CMYK color mode with an embedded ICC profile matching the target print standard (SWOP, GRACoL, ISO Coated, etc.).

The browser-based AVIF to TIFF converter on this site produces TIFF files in RGB color mode (matching the AVIF source). If your print workflow requires CMYK conversion, you will need to open the TIFF in Photoshop or a color-managed application and perform the RGB-to-CMYK conversion there, applying the appropriate ICC profile for your printer and paper combination.

For simple print jobs where RGB TIFF is acceptable, the browser-based output is ready to use immediately after conversion.

Archiving Best Practices with TIFF

If your goal is long-term digital preservation, TIFF is an excellent choice, and there are a few best practices worth following:

• Keep the original AVIF. Do not delete your AVIF source files after converting to TIFF. Store both — AVIF for web delivery and TIFF for the archival master.
• Use descriptive filenames. TIFF archives benefit from consistent, descriptive naming. The converter preserves your original filename stem and changes the extension to .tiff.
• Store on reliable media. TIFF files are large. Ensure you have sufficient storage and backup capacity before archiving large batches of high-resolution TIFF masters.
• Embed metadata. Professional archival TIFF files typically include EXIF and IPTC metadata. The browser converter preserves pixel data but does not inject new metadata — verify that your source AVIF metadata was embedded if this matters for your workflow.
