TIFF to AVIF Converter
FileFlip converts TIFF to AVIF entirely inside your browser, using ImageMagick compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert a TIFF file to AVIF?#
- Drop your TIFF file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to AVIF and the conversion starts on its own. FileFlip downloads 14.1 MB of WebAssembly the first time and nothing after that, then runs ImageMagick on your own machine.
- Save the AVIF file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting TIFF to AVIF lose quality?#
Yes, once. TIFF keeps everything and AVIF does not, so this is the first time the file meets a lossy encoder. At high quality the difference is hard to see, and it is worth keeping the TIFF original, because every later re-save of the AVIF loses a little more.
Is it safe to convert TIFF files online?#
Yes, because nothing is uploaded. FileFlip converts TIFF files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What TIFF to AVIF actually does to the file#
Converting TIFF to AVIF runs on ImageMagick, downloads 14.1 MB of WebAssembly the first time and nothing after that, encodes a lossless source with a lossy encoder for the first time, keeps EXIF metadata, ICC colour profile and transparency, and drops extra images.
| Engine | ImageMagick |
|---|---|
| Conversion path | One step: TIFF → AVIF |
| Downloaded to your browser | 14.1 MB, once, then cached by your browser |
| Quality | Lossy, first generation |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
What survives the conversion
| What is in the file | This conversion | Why |
|---|---|---|
| EXIF metadata | Kept | Carried through into the converted file. |
| ICC colour profile | Kept | Carried through into the converted file. |
| Transparency | Kept | Carried through into the converted file. |
| Extra images | Dropped | The target format has nowhere to put it. |
Worth knowing before you start:
- ImageMagick is asked for a single image, so only the first frame, page, or icon size is read
What is a TIFF file?#
A TIFF file stores one or more raster images, usually uncompressed or losslessly compressed, inside a tagged container that scanners, printers, and publishing software rely on to keep exact pixel data intact through repeated edits.
Use TIFF for scanned documents, print production, and archival photography, where preserving every pixel losslessly matters more than file size.
Convert TIFF to JPEG or PNG when the image needs to go on the web or be shared casually, since browsers cannot display TIFF and the files are far bigger than screen viewing requires.
What is an AVIF file?#
An AVIF file holds a still image or short animation encoded with the AV1 video codec, packaged inside a HEIF-style container that also carries HDR and wide-colour-gamut data alongside the pixels.
Use AVIF for web images where file size matters most, since it now decodes natively in every major browser and beats JPEG and WebP on compression at the same quality.
Convert AVIF to JPEG or PNG when a file is headed somewhere that still rejects it, such as an older content management system, a print workflow, or an app without AV1 decoding.
TIFF to AVIF questions people ask#
What is a TIFF file used for?
TIFF files are used for scanned documents, professional photography, and print production, because the format can store an image with no compression loss at all. Publishing software, print shops, and archives favor it precisely because a TIFF looks identical no matter how many times it is opened and resaved.
Why are TIFF files so large?
TIFF files are large because most are saved uncompressed or with a lossless scheme like LZW, which shrinks a file far less aggressively than lossy JPEG compression does. A high-resolution scan saved as TIFF can easily run five to ten times the size of the same image saved as a JPEG.
Can I open a TIFF file in a web browser?
No browser displays TIFF files directly; typing a .tiff file's path into the address bar just triggers a download instead of a preview. The format has to be converted to JPEG or PNG before it can appear on a web page.
Is a TIFF file the same as a camera RAW file?
No, TIFF is a separate format from a camera's RAW file, though the two are often confused because both are used for high-quality photography. RAW stores unprocessed sensor data specific to a camera model, while a TIFF holds a fully processed, already-decoded image, which is why many RAW converters export their finished output as TIFF.
