Frequently Asked Questions
How do I convert JPG to AVIF online?
Drag and drop your .jpg or .jpeg file (or click to browse). The converter decodes the JPEG and re-encodes as AVIF — typically lossy with quality ~75 (perceptually similar to JPEG quality 85). Download the .avif result. Conversion runs through our image pipeline; files are not stored or logged after processing. AVIF encoding is CPU-intensive — typical conversion takes 1-5 seconds per image.
Will converting JPG to AVIF improve image quality?
No — JPEG to AVIF can never gain quality the JPEG already lost. What you DO gain: significantly smaller files (typically 30-50% smaller) at the same visual quality, plus AVIF's modern features (alpha, HDR — though JPEG had neither). Don't expect the AVIF to look better than the source JPEG; expect it to look the same at a much smaller file size. For maximum quality, start from a lossless source (PNG, TIFF, RAW) rather than re-encoding from JPEG.
Are my images uploaded to a server?
Your image is processed by our image pipeline and returned to your browser. We don't store, log, or share your images — they're discarded immediately after processing. The TLS connection protects images in transit. For maximum privacy with sensitive photos, run AVIF encoding locally with libavif (`avifenc -q 75 input.jpg output.avif`) or `magick input.jpg output.avif` via ImageMagick.
Does the conversion preserve EXIF metadata?
EXIF metadata is typically stripped during conversion — privacy benefit (removes GPS and camera info from photos you share) but loses orientation tags. The encoder bakes orientation into the pixel grid before stripping, so the AVIF displays correctly. AVIF supports XMP metadata natively, but this converter doesn't usually carry EXIF across by default. For preserving EXIF, use a local tool like exiftool to copy metadata after encoding.
What is AVIF and when should I use it?
AVIF (AV1 Image File Format) is a modern image format published in 2019, based on the AV1 video codec. ~50% smaller than JPEG at equivalent perceived quality, supports alpha transparency, HDR colour, and animation. Decoding is supported in Chrome 85+, Firefox 93+, Safari 16+, Edge 121+ — ~95% browser coverage in 2026. Use AVIF for web hero images, product photos, and anywhere file size matters and modern browsers are the audience.
Why does AVIF encoding take so long?
AVIF uses the AV1 video codec internally, which performs extensive analysis to find the optimal encoding for each block of the image — slower than JPEG's relatively simple DCT transform. Typical conversion takes 1-5 seconds per image on this tool's infrastructure; very large images (4K+) can take 10+ seconds. The trade-off is worth it for the resulting file size. For repeated batch encoding, use libavif's avifenc with a lower speed setting (`-s 6` for faster) on a local machine.
Can I control the AVIF output quality?
Quality ~75 is the visually-lossless sweet spot for AVIF (roughly equivalent to JPEG quality 85). Quality 60 still looks excellent in most cases with significantly smaller files. Quality 50 starts to show artifacts on detailed content. For archival quality, use 85+ or switch to lossless mode (much larger files). For aggressive web optimisation, 50-60 is the practical floor — past that, JPEG at the same quality might look better.
When should I convert JPG to AVIF?
Three common cases. (1) Web performance — Core Web Vitals (LCP especially) benefit from AVIF's smaller file sizes; LCP improvements of 100-300ms are typical. (2) Bandwidth-constrained delivery (mobile users, CDN cost optimisation). (3) Storage cost reduction for large photo archives. Implement with `<picture>` element fallbacks for older browsers: `<picture><source srcset='image.avif' type='image/avif'/><img src='image.jpg'/></picture>`. Use [JPG to WebP](/tools/jpg-to-webp/) as a more compatible alternative.
