AVIF to TIFF Converter
Convert AVIF to TIFF in your browser. AVIF files usually come from image CDNs, modern web build pipelines and some recent phones; TIFF is the better fit for printing, scanning and archival masters. You get an uncompressed 8-bit RGBA TIFF with the resolution recorded. Nothing is uploaded.

Why use Aback Images for avif to tiff
Where the TIFF goes next
TIFF opens in Photoshop, Lightroom, GIMP, Affinity, macOS Preview, Windows Photos and print RIPs.
TIFF next to AVIF
The TIFF is written uncompressed, so expect it to be several times larger than the AVIF, which stores lossy or lossless AV1 intra-frame coding.
No new artefacts
AVIF is already lossy, since it stores lossy or lossless AV1 intra-frame coding; the TIFF keeps the decoded pixels uncompressed, so this step adds no compression damage of its own.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
AVIF vs TIFF
What changes from AVIF to TIFF
Encoding: the AVIF uses lossy or lossless AV1 intra-frame coding; TIFF uses none, LZW, PackBits, Deflate or JPEG, chosen per file, and the download is an uncompressed 8-bit RGBA TIFF with the resolution recorded.
Bit depth: 8, 10 or 12 bits per channel in the AVIF; TIFF allows 1 to 16 bits per channel, or 32-bit floating point, and the TIFF written here has 8 bits per channel. 10 and 12-bit AVIFs, including HDR ones, are decoded to 8 bits per channel.
Colour: YUV 4:4:4 or 4:2:0 with BT.709, Display P3 or BT.2020 primaries, HDR curves possible in the AVIF; TIFF supports RGB, CMYK, Lab, greyscale or palette, often with an ICC profile, written here as 8-bit sRGB.
Transparency: the AVIF stores it as an auxiliary AV1 image stored beside the colour image; the TIFF keeps it as an extra sample declared in the ExtraSamples tag.
Animation: an AV1 image sequence under the 'avis' brand; the TIFF holds one image, so only the first frame is converted.
Metadata: the AVIF can carry EXIF, XMP and ICC stored as HEIF items; TIFF can carry EXIF, XMP, IPTC and ICC, all stored as tags, but nothing is copied across.
About AVIF
AVIF uses the AV1 video codec for still images. It is the most efficient widely supported format, often half the size of JPEG, with HDR, wide colour and transparency, but encoding is slow.
An AVIF is a HEIF file, the same ISO base media boxes as MP4, with the brand 'avif'. The picture is an AV1 key frame stored as an image item, and its size, colour and pixel layout are item properties.
AVIF files usually come from image CDNs, modern web build pipelines and some recent phones.
About TIFF
TIFF is the professional archive and print format. It can hold multiple pages, high bit depths and lossless data, and is common in scanning, publishing and GIS.
A TIFF begins with 'II' or 'MM' for the byte order and the number 42, then an offset to the first image file directory (IFD): a table of tags giving the size, compression, colour model and the location of the strips or tiles of pixels. Each further page is another IFD.
When converting AVIF to TIFF makes sense
TIFF is the better choice for printing, scanning and archival masters, while AVIF suits maximum compression on modern websites.
TIFF strengths: Lossless and print-ready; Multiple pages in one file; Preferred by print shops and archives. Drawbacks to weigh: Very large files; Browsers cannot display it; Many variants and compression schemes.
Limitations
- Almost any other format needs more bytes than AVIF for the same picture, so expect the file to grow.
- HDR and wide-gamut AVIFs are mapped to standard sRGB on decode, so very bright highlights can look flatter than on an HDR screen.
- The TIFF is written uncompressed for maximum compatibility, so it is large; print shops and archives generally expect that.
- Browsers other than Safari do not display TIFF, so it is not a format for the web.

Frequently asked questions
Does converting AVIF to TIFF lose quality?
TIFF is written uncompressed, so the pixels are stored exactly as decoded. Artefacts already in the AVIF stay, but nothing new is lost. 10 and 12-bit AVIFs, including HDR ones, are decoded to 8 bits per channel.
Is transparency kept in the TIFF?
Yes. AVIF stores it as an auxiliary AV1 image stored beside the colour image, and the TIFF is written with an alpha channel, so transparent areas stay transparent.
Will my animated AVIF stay animated?
No. TIFF holds a single image, so only the first frame is kept. Convert to animated WebP, APNG or GIF to keep the motion, or export every frame with the GIF Frame Extractor.
Which apps open TIFF files?
Photoshop, Lightroom, GIMP, Affinity, macOS Preview, Windows Photos and print RIPs. It opens in Safari only; other browsers do not display TIFF.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
