SVG to AVIF Converter

Turn SVG files into AVIF in a couple of clicks. SVG is an XML-based vector format that scales to any size; AVIF is a next-gen format with the best compression available today. Some detail is discarded to fit the target format; how much depends on the format and your settings.

How to use it

  1. 1

    Add your SVG files

    Drag them onto the drop area, choose them from your device, or paste them from your clipboard. You can queue several at once. Nothing is sent anywhere — the file stays on this device.

  2. 2

    Adjust the settings if you want to

    The defaults suit most people. Open Advanced to control quality and metadata removal.

  3. 3

    Convert and download

    Press Convert. Everything happens on your own device — nothing is uploaded. Download files one by one, or grab them all as a ZIP.

Privacy, in plain words

Is it safe? Your SVG file is not uploaded anywhere

What “uploaded” normally means. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website. That copy is what the word “upload” means, and it is the part nobody explains.

What happens instead. This site does not do it. There is no server here that receives files, so your SVG file is read, converted and handed back by the browser you are using right now. It never travels — so there is no copy to store, read, leak or hand over.

Check it yourself in ten seconds

Turn off your Wi-Fi after this page has loaded, then convert a file anyway. It still works, because everything needed is already on your device.

The longer explanation of how this works, and the full detail of what is and is not stored on the privacy page.

Why this matters more than it sounds

Photographs carry more than what is in the frame — most also carry the time, the device and often the GPS coordinates where they were taken. It matters more than it sounds, because of what images usually are:

Passport and visa photos

biometric-grade images of your face

Screenshots of private messages

conversations that included other people

Photos of ID cards and licences

the usual way people send identity documents

Screenshots of bank transfers

account details, and proof of what you paid whom

A file that is never sent cannot be kept, leaked, subpoenaed or used to train anything. That is a property of how this works, not a promise about how carefully it is run.

SVG and AVIF explained

SVG is not a picture of an image — it is XML describing shapes, paths and text. Because it stores instructions rather than pixels, it renders perfectly at any size, from a favicon to a billboard.

AVIF stores still images using the AV1 video codec's intra-frame compression. It generally achieves the smallest files of any widely supported format, and it handles wide colour gamut and HDR, which JPEG cannot.

Where SVG files come from
Design tools like Figma and Illustrator, and icon libraries.
Where AVIF is used
Performance-focused websites and modern image pipelines.

SVG vs AVIF

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

Why convert SVG to AVIF?

People make this switch when they run into the limits of SVG: photographic content, or when the recipient needs a fixed-size bitmap. AVIF is the better fit when you control the audience (a modern website) and file size is the priority.

SVG limitations that prompt the switch
Useless for photographs. Complex illustrations can be slower to render than a bitmap. Can carry scripts, so SVGs from untrusted sources need care.
What you give up
Encoding is slow compared with JPEG or WebP. Desktop application support is still thin.

Does converting SVG to AVIF reduce quality?

AVIF compresses without discarding data, but it cannot represent everything an SVG file holds. What does not fit is discarded permanently, so converting the result back will not restore it. Keep the SVG original if it is the only copy.

Converting a photo to SVG does not make it vector. It embeds the same bitmap inside an SVG wrapper — the file gets bigger and gains nothing.

Good to know

SVG to AVIF Converter — questions

How do I convert SVG to AVIF?

Drop your SVG file onto the area above, then press Convert. The AVIF file saves straight to your device. You do not need an account, and there is no watermark.

Is it safe to convert SVG files here — are they uploaded to a server?

No, nothing is uploaded. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website; it is converted there and sent back. That copy is what "upload" means, and it is the part that puts your file out of your control. This site does not do it. Your SVG file is read and converted by the browser you are using right now and never leaves this device, so there is no copy for anyone to store, read or hand over. You can prove it: turn off your Wi-Fi after this page loads and the conversion still works.

Can I convert confidential SVG files, like bank statements or contracts?

Yes, and that is the case this site was built for. Because the file never leaves your device, a confidential document is no more exposed than it is sitting in your own folder — there is no transfer, no copy on someone else's hardware, no retention period to read about and no staff with access. Nothing is logged about the file either: not its name, not its size, not its contents. The one thing worth saying plainly is that this protects the file in transit and at rest on our side, not from anything already on your own computer.

What should I know before converting SVG to AVIF?

The vector is rasterised at a fixed pixel size, so the result no longer scales infinitely. Pick a generous width if you plan to print it.

Does converting to AVIF reduce quality?

AVIF uses lossy compression, so some data is discarded. At the default quality the difference is very hard to see or hear; raise the quality setting if you need to be certain, at the cost of a larger file.

How large a file can I convert?

Up to 120 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large images may run out of memory on a phone — those are better converted on a laptop.
