What is an AVIF file?

An image format built on the AV1 video codec, the same generation of compression Netflix and YouTube stream with. It stores photos in roughly half the bytes of JPEG at equal quality. It supports transparency, animation and HDR, and renders in about 95% of browsers in 2026.

How do I open an AVIF file on Windows 11?

Install the free "AV1 Video Extension" from the Microsoft Store and Windows Photos will open AVIF, usually. The extension is video-oriented, and some AVIFs still fail or thumbnail slowly. The reliable route is converting the file to JPG once.

Why won't Windows Photos open my AVIF?

Either the AV1 extension is missing, or you've hit its known gaps. It is a video decoder pressed into image duty, and certain AVIF variants trip it. Rather than debugging codecs, convert the file to JPG or PNG; every viewer on earth opens those.

How do I convert AVIF to JPG or PNG?

Drop the file into the converter, pick JPEG or PNG as the output, and download. Up to 50 files per run with one ZIP. JPG is the "opens everywhere" target. PNG is for when you need transparency preserved or lossless onward editing.

Is AVIF better than WebP?

Smaller, yes: typically 15–40% at equal quality. On our reference photo, AVIF measured 114.7 KB where WebP needed 188.3 KB. WebP counters with slightly wider support and faster encoding. For the web, serve AVIF first with a WebP fallback and take both wins.

Does Photoshop support AVIF?

Only via a plugin. Adobe has not shipped native AVIF support. GIMP opens it natively, macOS Preview works from Ventura, and Figma and Canva imports are inconsistent. For an editing workflow, convert to PNG first; it round-trips losslessly from the decoded AVIF.

How do I batch convert AVIF files?

Drop up to 50 per run, in either direction: AVIF out to JPG/PNG/WebP, or JPG/PNG/WebP/HEIC in to AVIF. You get one ZIP download, filenames preserved, measured sizes per row, no signup, and a 300-image daily allowance. Mixed input formats in one batch are fine.

Does AVIF support transparency and animation?

Yes, both are in the specification. Transparency survives every conversion that targets a format with alpha (PNG, WebP). Converting to JPG flattens it onto white, and the result preview shows that before you download. We decline animated AVIF inputs rather than silently flattening them.

Why are websites sending me AVIF images?

Because it is the smallest mainstream format. Sites cut image bandwidth 30–50% by serving it, and browsers negotiate formats automatically. You only notice when you save an image and something older refuses to open it. Converting that saved file takes a single drag and drop.

Which browsers support AVIF?

Chrome 85+ (2020), Firefox 93+ (2021), Safari 16.1+ (2022), Edge 121+ (2024): about 95% of global traffic. The gap is old browsers and some embedded webviews. That is why sites serve AVIF inside a picture element with a WebP or JPEG fallback.

What happens to my files here?

We keep nothing. We process your files, wipe them automatically, and never archive them or use them for anything else. We strip metadata from outputs by default. No account, no watermark, and a 300-image daily allowance counted live beside the tool.

Which direction do you need?

This page runs both ways, because AVIF traffic splits in two. "I have an AVIF that won't open": saved from a website, sent by a designer, rejected by Photoshop. Convert it out, to JPG (opens everywhere), PNG (keeps transparency), or WebP (for platforms that accept WebP but not AVIF). "I want my images AS AVIF", for a faster site: convert in, from JPG, PNG, WebP or HEIC. The tool above handles either; the pair pages go deep on each.

Why won't my AVIF open? The rescue guide

Windows 10/11: Photos needs the free AV1 Video Extension from the Microsoft Store. Even then, some AVIFs fail because the extension is a video decoder doing image duty. Photoshop: plugin only, still no native support. macOS: Preview opens AVIF from Ventura (2022) onward; older Macs don't. Office, older Android galleries, email clients: mostly no. The pragmatic fix is one conversion to JPG or PNG rather than a codec hunt on every machine the file will ever touch. That is what the tool above is for.

What AVIF is worth, measured both ways

Conversion	Before	After	Change
AVIF → JPG (Auto)	175.3 KB	73.3 KB	-58%
AVIF → WebP	175.3 KB	108.2 KB	-38%
JPG → AVIF (q60)	188.3 KB	114.7 KB	−39%
PNG photo → AVIF	1382.4 KB	69.8 KB	−95%

Converting OUT of AVIF trades bytes for compatibility, so sizes grow. Converting IN is where the savings live. Reference files, Auto quality.

How these numbers are measured: every byte count on this page is the size of the actual encoded file our engine produced from the named source image. Those are the same bytes you would download, not an estimate or a best case. Rerun any of them yourself: drop your own file into the tool above and the meter reports your real result.

What survives each conversion?

Transparency: preserved into PNG and WebP; flattened onto white for JPG (JPEG has no alpha, and we preview the flattening before you commit). HDR and 10-bit colour: tone-mapped to standard 8-bit sRGB on every output, the same thing any JPG/PNG workflow does. Animation: declined rather than silently reduced to frame one. Metadata: stripped by default on every output; keep it with one checkbox in Advanced settings.

When converting out of AVIF is a mistake

The file is only for your own website? Keep AVIF. 95% of browsers render it and it is the smallest option. Convert out only for the tools that reject it.
Bulk-converting a whole site "for safety"? You would trade a 30–50% bandwidth win for a fear. Use a picture-element fallback instead and keep the AVIFs.
Passing files to a designer? Ask what they need first. PNG for editing beats JPG, and the original source file beats both.
