About converting TIFF to AVIF
Convert TIFF to AVIF to shrink huge print scans into web-friendly files without visible quality loss. Scanned documents and photographic masters that weighed tens of megabytes become lightweight, browser-ready images.
TIFF is the archival and print industry standard, created in 1986. It is a flexible container that magazines, photographers, and scanners have relied on for decades. AVIF is the newest mainstream image format, derived from the royalty-free AV1 video codec and standardized in 2019. It represents the current ceiling of compression efficiency.
This conversion crosses compression philosophies: TIFF is lossless and AVIF is lossy. That matters for file size, editability, and how the image behaves if you open and save it again later.
When to use TIFF vs AVIF
Choose AVIF when modern websites, image CDNs, progressive web apps, and any workflow where bandwidth savings outweigh legacy compatibility. Keep TIFF when print production, high-end photography, scanned documents, medical imaging, and any workflow where quality matters more than file size.
On strengths: TIFF brings print-shop acceptance, multi-page documents, layer preservation, and lossless storage that survives repeated edits without generational quality loss. AVIF brings often 50% smaller than JPEG at the same perceptual quality, with strong protection against compression artifacts on faces, gradients, and flat color.
The trade-off: Files are far too large for web use, browsers cannot display TIFF natively, and most consumer platforms treat it as an exotic format. Encoding is computationally heavier, very old devices may render it slowly, and some legacy editors and operating systems still do not support it.
How to convert TIFF to AVIF
The converter runs entirely in this browser tab — there is no upload, no account, and no file-size harvesting. Follow these steps:
- Drop your TIFF files onto the converter above, or click the drop zone to browse. Up to 20 files can queue at once, each up to 25 MB.
- The output defaults to AVIF. Adjust the quality slider if the format is lossy, or resize/crop first if you also want to change dimensions.
- Press Convert. Decoding and encoding happen in browser memory using Canvas — your pixels never leave the device.
- Preview the result, then download it individually or grab the whole batch as a ZIP.
About TIFF — Tagged Image File Format
TIFF is the archival and print industry standard, created in 1986. It is a flexible container that magazines, photographers, and scanners have relied on for decades.
Typical uses: Print production, high-end photography, scanned documents, medical imaging, and any workflow where quality matters more than file size.
About AVIF — AV1 Image File Format
AVIF is the newest mainstream image format, derived from the royalty-free AV1 video codec and standardized in 2019. It represents the current ceiling of compression efficiency.
Typical uses: Modern websites, image CDNs, progressive web apps, and any workflow where bandwidth savings outweigh legacy compatibility.
Tips for a clean TIFF → AVIF conversion
- Work from the highest-quality TIFF source you have. Converting from an already-compressed copy stacks compression artifacts on top of each other.
- Aim for quality 85–90. Above that, file size climbs for almost no visible gain; below 70, banding and blockiness appear around edges.
- Batch similar images together — files with comparable dimensions convert in the same pass, which keeps the workflow fast.
- Keep the original file. Even lossless conversions can subtly change color profiles, and the source is your safety net.
Frequently asked questions
Is this TIFF to AVIF converter free?+
Yes. All image conversions are completely free with no sign-up, no watermarks, and unlimited usage.
Are my images uploaded to a server?+
No. All conversion happens locally in your browser via the HTML5 Canvas API. Your files are never uploaded or stored anywhere.
Will converting TIFF to AVIF reduce quality?+
Because TIFF is lossless, the conversion starts from perfect pixel data. AVIF uses lossy compression, so the encoder discards information it considers imperceptible — keep the quality slider between 85 and 100 for a result that is visually indistinguishable from the original.
Can I convert multiple TIFF files at once?+
Yes — drop up to 20 files into the converter and they will all be processed in a single batch. Each file can be up to 25 MB. The batch downloads as a ZIP, or you can save results individually from the preview.
Does this converter work on phones and tablets?+
Yes. The converter is a responsive web app that runs in any modern mobile browser — iOS Safari, Chrome for Android, and others. Files are processed on-device, so mobile uploads are not sent anywhere and the connection speed does not affect conversion time.
