Will JPG to AVIF keep transparency?

No. JPEG never stores alpha. The AVIF you download is opaque. Use PNG to AVIF or WebP to AVIF when the source has transparency.

What quality should I pick?

Try 75–85 for web heroes. Raise toward 90 for print-adjacent masters you still want smaller than PNG. Compare against the original JPG before publishing.

Browser canvas conversion typically strips EXIF. That is usually desirable for privacy on the public web; keep a JPG master if you need metadata.

Can I convert many JPGs at once?

Yes—batch in the converter above. AVIF encoding is CPU-heavy; on older phones, split large queues.

About JPG to AVIF conversion

JPEG is universal for cameras and email, but AVIF often delivers similar photo quality at a smaller size for modern websites and CDNs. Encode JPG to AVIF locally when your stack already serves AVIF.

Why encode JPG to AVIF

Often smaller files than JPEG at similar visual quality
Adjustable quality slider for delivery vs detail
Ideal for modern sites, CDNs, and image CDNs that accept AVIF
Runs in your browser—photos never upload to our servers

When to convert JPG to AVIF

You publish photos on a site that already supports AVIF
Your CDN or image pipeline negotiates AVIF for capable browsers
You want to cut bandwidth while keeping photographic look
Frameworks or CMS themes list AVIF among accepted formats

JPG remains the capture and interchange format for cameras, phones, and email. AVIF is often the better long-term delivery format once your audience can decode it.

This page encodes JPEG into AVIF in your browser. JPG has no alpha channel—output AVIF is opaque. For transparent graphics, use PNG to AVIF or WebP to AVIF instead.

Typical JPG to AVIF workflows

Export camera JPEGs for a blog or storefront that serves AVIF, recompress stock photos before CDN upload, or migrate a photo library to AVIF for bandwidth savings. Start quality around 70–85 and compare file size to the original JPG.

Keep JPG or move to AVIF?

Keep JPG when partners, printers, or legacy apps require .jpg. Switch to AVIF when your site can fall back gracefully and you care about bytes on the wire.

Encoding to AVIF is heavier than exporting JPG—large batches may take longer. Everyday photos usually finish in seconds on modern devices.
