Why convert JPG to AVIF?

If you're running a website or an app, every kilobyte counts. Huge JPGs slow down your page, which annoys users and hurts your Google rankings. AVIF is basically a cheat code for performance. It compresses images 30–50% smaller than JPG without ruining the quality. Almost all modern browsers (Chrome, Safari, Firefox) fully support it, meaning you get massive speed boosts for free.

Is there a catch?

Not really, but here's the deal: AVIF is a modern format, which means older, legacy apps or super old browsers might not know what to do with it. If you're sharing photos with your grandma who uses an iPad from 2013, stick to JPG. But if you're building a website, serving an AVIF to modern browsers and keeping a JPG fallback is the ultimate pro move. You get lightning-fast speeds for 95% of users without breaking anything for the rest.

How to convert JPG to AVIF

It all happens right here in your browser. No accounts, no data harvesting, no nonsense:

  1. Hit "Convert to AVIF →" at the top of this page, or just drag and drop your JPG file anywhere on the screen.
  2. Your browser takes over and instantly starts crunching the image. Because AVIF uses some crazy advanced compression, this step takes a couple of seconds.
  3. You'll see a preview pop up. You can adjust the quality slider if you want to compress it even more.
  4. Click download. Your shiny new AVIF saves right to your device. Check the file size—you'll be amazed.

When to use AVIF over JPG

Use AVIF whenever you control where the image is going. Building a Next.js site? Drop AVIFs in there. Running a blog? Swap your hero images to AVIF. The bandwidth savings are ridiculous, and your Core Web Vitals will thank you. But if you're sending a meme in a group chat or uploading a profile pic to an older forum, stick to JPG for guaranteed compatibility.

FAQ

Do my photos get uploaded to a server?

Nope. Everything runs locally in your browser. You could literally turn off your Wi-Fi right now and it would still work. Total privacy, guaranteed.

Is this actually free?

Yeah, 100%. Because your phone or computer is doing all the hard work, we don't have insane server bills. So we keep it free for everyone.

Can I do a bunch of JPGs at once?

Batch processing in one window is coming soon! For now, just open a few tabs and run them at the same time—it works great.

Why does AVIF take a few seconds to convert?

AVIF gets its insanely small file sizes by doing a LOT of math. It's doing advanced compression tricks, which takes a bit more processing power than older formats. It's worth the wait for the space savings.

Which browsers actually support AVIF?

Basically everyone that matters in 2026. Chrome, Safari, Firefox, and Edge all support it perfectly. We're talking over 95% of global web traffic.

Does this strip out my location data?

We keep your metadata (like camera model and settings) by default. If you want to strip out the GPS location before posting online, there's a toggle for that in the advanced options.

Will this make my website faster?

Yes, dramatically. Images are usually the heaviest part of a webpage. Cutting your image sizes in half means your site loads twice as fast, which Google loves for SEO.
