Drop JPG (JPEG, JFIF) 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.
Press Convert. Open Options first if you want to change the defaults. The work happens in this tab.
Save the AVIF, or download everything as one ZIP if you converted several files.
The JPG to AVIF converter is part of this page and runs inside your browser. Your photos are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
AVIF usually halves a JPG's file size at similar visual quality, which makes it the strongest option for image-heavy web pages. Chrome, Firefox, Edge and Safari 16 or later display it. Encoding AVIF is slow by design: the codec spends a lot of effort to save those bytes.
The defaults suit most files. Under Options you can set the quality, aim for a target file size and resize the result.
The AVIF encoder is a WebAssembly module that downloads the first time you convert to AVIF and is cached afterwards.
JPG (also written JPEG) is the format almost every camera and website uses for photographs. It throws away detail the eye barely notices to keep files small, which is why it suits photos and struggles with sharp text or flat colour.

JPG converterAVIF 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.

No. The JPG to AVIF conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
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.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
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 JPG file, press Convert and save the AVIF. There is nothing to install.
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.
