AVIF Converter - Convert Any Image to AVIF FreeNever Been Easier
AVIF (AV1 Image File Format) is the most efficient image format in mainstream use today. It cuts file sizes by around 50% versus JPG at the same quality - roughly double WebP’s savings - while also supporting HDR, 10-bit color, and wide gamut that JPG simply cannot represent.

Supports JPG, PNG, GIF, SVG, ICO, BMP, AVIF, WebP
PixConvert encodes AVIF right in your browser using WebCodecs, with no uploads and no waiting in a queue. Batch-convert a whole library, fine-tune quality with the slider, and compare results with the before/after preview. Chrome, Firefox, Safari 16+, and Edge all decode AVIF, making it a safe default for web delivery in 2026.
Why convert to AVIF?
About 50% smaller than JPG
AV1’s codec far surpasses JPEG’s 30-year-old algorithm. At equal quality, AVIF files are routinely half the size.
More efficient than WebP
AVIF beats WebP by 20-30% at equivalent quality and adds HDR, 10/12-bit color, and wide gamut support.
Strong Core Web Vitals boost
Smaller hero images mean faster LCP. AVIF is the single most effective format change you can make for page speed today.
Private and instant
Encoding runs on your device with no server round-trip. Private images stay private, and there is no upload limit.
How to convert images to AVIF
- 1
Upload your images
Drag and drop or browse for JPG, PNG, WebP, or other images. Batch processing handles many files at once.
- 2
Choose AVIF output
AVIF is preselected. Set quality via the slider - around 50-60 already matches or beats a quality-80 JPG visually.
- 3
Compare with the preview
The slider view shows original and converted side by side. AVIF’s efficiency lets you push quality lower than with WebP.

Frequently asked questions
Is AVIF really smaller than WebP?
Yes, generally 20-30% smaller at equivalent quality, and the gap widens at lower bitrates. For maximum compression, AVIF is the current best choice.
Which browsers support AVIF?
Chrome 85+, Firefox 93+, Edge, Opera, and Safari 16+ all decode AVIF. As of 2026 that covers well over 95% of global browser usage.
Why is AVIF encoding slower than WebP?
AV1 compression is computationally heavier. In-browser encoding uses hardware acceleration where available; on older devices expect a few seconds per image.
Are my images uploaded anywhere?
No. AVIF encoding runs entirely on your device. Files never leave your computer.
