Is AVIF better than WebP?

In terms of compression efficiency, yes—AVIF is 20–30% better than WebP. It also supports features WebP lacks (HDR, 12-bit color, film grain synthesis). However, WebP has much broader browser support (96%+ vs ~70% for AVIF) and faster encoding/decoding speeds. For most websites in 2025, WebP remains the more practical choice.

Does converting AVIF to JPG lose HDR information?

Yes. JPG does not support HDR. High dynamic range content in the AVIF is tone-mapped down to standard dynamic range during conversion. The resulting JPG will look correct and natural on standard displays, but the extended brightness range of the HDR original is lost.

How much larger will my JPG be compared to the AVIF?

Expect the JPG to be roughly 2–3x the size of the AVIF source at equivalent visual quality. A 120 KB AVIF commonly produces a 250–350 KB JPG. This reflects the fundamental compression advantage of AV1 intra-frame coding over JPEG's DCT-based compression.

Can I convert AVIF with transparency to JPG?

JPG does not support transparency. If your AVIF has an alpha channel, transparent areas will be filled with white (or your chosen background color). If transparency must be preserved, convert AVIF to PNG instead using our AVIF to PNG converter.

Which browsers support AVIF in 2025?

Chrome 85+, Firefox 93+, Edge 121+, Opera 71+, and Samsung Internet 16+ all support AVIF. Safari (macOS and iOS) does not. This puts global AVIF support at approximately 70%, meaning nearly one-third of web users cannot see AVIF images without a fallback.

How to Convert AVIF to JPG — Make Next-Gen Images Widely Compatible

AVIF (AV1 Image File Format) is the most advanced image format on the web today. Built on the royalty-free AV1 video codec, AVIF delivers images 20–30% smaller than WebP and up to 50% smaller than JPG at equivalent quality. It supports HDR, wide color gamut, transparency, and both lossy and lossless compression. Chrome has supported AVIF since version 85 (August 2020), Firefox since version 93 (October 2021). But there is a giant hole in the support matrix: Safari. As of early 2025, Safari on both macOS and iOS does not support AVIF natively. That means every iPhone and iPad user—roughly 30% of global mobile traffic—cannot see AVIF images. For websites that have adopted AVIF without proper fallbacks, this creates a massive compatibility problem. Converting AVIF to JPG is the practical solution when you need images that work on every device. Our browser-based converter handles the AVIF decode (supported in Chrome and Firefox) and outputs high-quality JPGs without any server interaction.

Step-by-Step Guide

Upload Your AVIF Image

Drag one or more .avif files onto the converter. AVIF files up to 50 MB are supported. The browser must support AVIF decoding—Chrome 85+, Firefox 93+, and Edge 121+ all include the dav1d decoder. If you are using Safari, you will need to switch to Chrome briefly for the conversion.

Set JPG Quality Parameters

Select your output quality. At 90%, the JPG will look identical to the AVIF source in practical viewing scenarios. At 85%, you get a good balance of quality and file size. AVIF sources are often very high quality with few compression artifacts, so you can use slightly higher JPG quality settings (90–95%) without ballooning the file size.

Download Your JPG

Click "Convert" and the AVIF is decoded to raw pixels then re-encoded as JPG. The conversion takes 1–3 seconds depending on image size. Download the result. The tool shows the file size delta—AVIF files are typically 50–70% smaller than JPG, so expect the converted JPG to be significantly larger.

Tips & Best Practices

AVIF files are typically 50% smaller than JPG at equivalent quality. A 100 KB AVIF at quality 80 will become roughly a 200–250 KB JPG at the same perceived quality. This is the compression efficiency you are trading for compatibility.

AVIF supports 10-bit and 12-bit color depth with HDR (PQ and HLG transfer functions). When converting to JPG, HDR is tone-mapped to SDR using a simple Reinhard curve. The result looks correct on standard displays but loses the HDR luminance range.

Safari does not support AVIF (as of early 2025), which locks out roughly 25–30% of web users from seeing AVIF images. If your website uses AVIF, always include a JPG or WebP fallback via the <picture> element—do not serve AVIF exclusively.

If you are downloading AVIF images from a website and they will not open, check the file extension. Some CDNs serve AVIF images with a .jpg extension via content negotiation. Rename the file to .avif before trying to open or convert it.

WordPress 6.5+ supports AVIF uploads natively, but older versions do not. If your CMS rejects AVIF, convert to JPG for upload. The CMS may then auto-generate WebP versions from your JPG if you have a conversion plugin installed.

AVIF has better support for film grain synthesis than JPG. If your AVIF contains encoded film grain (common in cinema-quality sources), this grain texture will be baked into the JPG output—it will not be lost, but it will not be as efficiently stored.

For images with text or sharp edges, AVIF at quality 60+ retains more detail than JPG at quality 80. When converting such images to JPG, use quality 90+ or the text will show noticeable ringing artifacts around the letterforms.

Google Chrome on Android automatically downloads AVIF images from websites. When you save an image from a site that serves AVIF to Chrome, you are saving an AVIF file. If you need JPG, converting is required.

Frequently Asked Questions

Safari does not support AVIF as of 2025. Apple has been slow to adopt the format despite being a member of the Alliance for Open Media that created AV1. Until Apple adds Safari support, AVIF files will not open natively on iOS or macOS. Use our converter in Chrome or Firefox to convert them to JPG.

AVIF is the future of web images—once Safari support arrives, it will surpass both JPG and WebP in adoption. Until then, AVIF to JPG conversion is the bridge between cutting-edge compression and universal compatibility. Convert your AVIF files now with our free, private, browser-based tool.
