Convert JPG to AVIF instantly. Drop your files or click to select — free, private, no upload. 100% browser-based.
Convert JPG images to AVIF and cut file sizes by 50-70% with virtually identical visual quality. AVIF is the next-generation image format used by Netflix, Google, and major tech companies — it delivers dramatically better compression than both JPG and WebP. Perfect for web developers and site owners who want the absolute smallest files without sacrificing quality. This tool runs entirely in your browser — no upload, no limits.
AVIF typically produces files 50-70% smaller than equivalent-quality JPG. A 500KB JPG often becomes 150-250KB as AVIF with no visible quality difference. This is significantly better than WebP (which saves 25-34% vs JPG).
AVIF is supported by Chrome, Firefox, Opera, and Samsung Internet. Safari added AVIF support in iOS 16 / macOS Ventura (2022). Edge supports it too. Overall, AVIF covers about 93% of web users.
AVIF quality numbers work differently than JPG. AVIF quality 50 looks equivalent to JPG quality 85-90. The AVIF encoder is much more efficient, so lower numbers still produce excellent results. Try 40-60 for most images.
AVIF produces smaller files (20-30% smaller than WebP at same quality), but encoding is slower and browser support is slightly narrower. Use AVIF if you want maximum compression. Use WebP if you need wider compatibility or faster encoding.
