Use AVIF for a modern website or application after testing browser, CMS, CDN, and device behavior. Keep TIFF for professional or archival use and provide a more compatible fallback when required.
Why convert TIFF to AVIF?
AVIF can turn a large TIFF source into a compact modern delivery asset for environments that support the codec. This is useful when the TIFF is a master file but the destination needs efficient transfer.

Understand the source and the output
| Format | Typical role | Compression | Transparency |
|---|---|---|---|
| TIFF | Scanning & professional imaging | Can use multiple compression modes | Capabilities depend on the TIFF content |
| AVIF | High-efficiency modern images | Lossy or lossless depending on encoder | Yes |
About the TIFF source
A flexible image container common in scanning, print, archival, and professional imaging workflows. Strong in professional imaging software; less convenient for ordinary web or messaging delivery.
Typical use: Scanning, archival sources, print workflows, high-quality intermediates, and professional imaging.
About the AVIF output
A modern format capable of strong compression efficiency for many photographic and graphic images. Good in modern browsers, but legacy applications and older workflows may still require a fallback.
Main trade-off: Encoding and decoding behavior, tooling support, and quality controls should be tested with the real workflow.
What changes during TIFF to AVIF conversion?
Conversion decodes the source image and creates a new file in the selected output format. The original file stays unchanged. The new file can differ in compression, file size, transparency support, metadata behavior, and compatibility even when the pixel dimensions remain the same.
The AVIF delivery copy can be lossy and may not retain TIFF-specific metadata or features. Preserve the source TIFF and evaluate the actual visual result rather than codec labels alone.
If the source is important, keep it as your master copy. A converted file is best treated as a delivery or compatibility copy unless you have verified that the new format preserves everything your workflow needs.
How this browser-first conversion works
- Add files. Drag supported images onto the converter or choose them from your device.
- Choose AVIF. The page is preset for this format pair, and a quality control appears only when the output codec uses one.
- Convert locally. Supported image bytes are processed in the browser with the image engine rather than sent through a conversion upload queue.
- Download results. Save individual files or package successful batch results into a ZIP.
Batch conversion runs sequentially to reduce browser memory pressure. If one image fails, the rest of the batch can continue, and the failed row can be retried without re-running successful files.
Before you convert
- Keep important source files until you have checked the converted output.
- Do not assume a larger output means the image gained real quality or detail.
- Check transparency requirements before converting to a format that cannot represent alpha transparency.
- For very large or unusual images, browser memory and runtime codec support can limit conversion even when the extension is recognized.
