JPG to AVIF — Free, Better Compression, No Upload

JPEG compression has been the web standard for photographic images for over thirty years, but its age shows in the file sizes it produces. A product photo, editorial image, or travel photograph optimized as JPG might be 150 to 400 kilobytes. The same image encoded as AVIF at matching visual quality often falls below 80 kilobytes. For an e-commerce site with thousands of product images, switching to AVIF delivery can reduce image bandwidth by more than half, improving page load speed and Core Web Vitals metrics that affect search ranking.

AVIF is supported in all major evergreen browsers as of 2023, making it a safe choice for production web delivery without needing extensive fallback logic. Cloudinary, Imgix, and Cloudflare Images all serve AVIF automatically when the client browser supports it. If you are managing your own image pipeline in Next.js, the built-in Image component handles AVIF conversion and serving automatically. For marketing teams uploading assets to a CMS, having pre-converted AVIF files speeds up the delivery pipeline.

Converting JPG to AVIF decodes the JPEG and re-encodes in AVIF, which introduces a small additional quality penalty since both steps involve lossy compression. In practice, converting a high-quality JPG at 90 percent to AVIF at quality 75 produces output that is nearly indistinguishable from the original JPG to most viewers while being dramatically smaller. AVIF also handles color gradients and fine detail with fewer visible blocking artifacts than JPEG at equivalent file sizes, so in many cases the AVIF actually looks better.

Typical sizes (12MP photo): JPG 2–5 MB → AVIF 0.8–2 MB.

On the free tier, AVIF output has a repeating formatdrop.com watermark; Pro output doesn't.

AVIF output is encoded at quality 85 — a small file with no visible difference for most photos.
