How to convert TIFF to AVIF

  1. Add your TIFF images

    Drop TIFF (TIF) files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.

  2. AVIF is already chosen

    Press Convert. Open Options first if you want to change the defaults. The work happens in this tab.

  3. Download

    Save the AVIF, or download everything as one ZIP if you converted several files.

Why ToAny

  • Private by construction

    The TIFF to AVIF converter is part of this page and runs inside your browser. Your images are never sent to ToAny or to anyone else.

  • No upload, no queue

    Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.

  • Free, without an account

    No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.

TIFF to AVIF: what to expect

TIFF files are large and do not display in most browsers or email clients. AVIF gives the smallest files of any widely supported image format. TIFF is at home in scans, print production and archiving; AVIF is the usual choice for the smallest images for websites.

The defaults suit most files. Under Options you can set the quality, aim for a target file size and resize the result.

Only the first page of a multi-page TIFF is converted. The AVIF encoder is a WebAssembly module that downloads the first time you convert to AVIF and is cached afterwards.

TIFF vs AVIF

TIFF

TIFF image

TIFF is the workhorse of scanning, publishing and archiving. It keeps full quality, can hold several pages and carries rich metadata, but files are large and browsers other than Safari will not display it.

Opens in Photo editors, scanners and print software; Safari is the only major browser that displays it

AVIF

AVIF image

AVIF stores a still image using the AV1 video codec. It usually beats both JPG and WebP on file size and supports transparency, HDR and wide colour. Current browsers display it, but many image editors, viewers and upload forms still do not.

Opens in Chrome, Firefox, Edge and Safari 16 or later; few desktop apps

Questions

Are my images uploaded anywhere?

No. The TIFF to AVIF conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.

Does converting TIFF to AVIF reduce quality?

A little: ToAny writes AVIF in its lossy mode, so a small amount of detail is traded for a much smaller file. At the default setting the difference is hard to notice. You can raise the quality under Options; there is no lossless setting.

Can I convert several TIFF files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert TIFF to AVIF on Windows, Mac, iPhone or Android?

The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the TIFF file, press Convert and save the AVIF. There is nothing to install.

Is there a file size limit?

Pictures of up to 120 megapixels are accepted (for example 12,000 by 10,000 pixels); a larger one is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
