How to use JPG to AVIF Converter

  1. 01

    Upload your JPG

    Drag and drop or select a JPG photo. Anonymous visitors can upload up to 20 MB; free accounts get 50 MB and 3 conversions every 30 days; paid plans allow 200 MB and batches of up to 100 files.

  2. 02

    Set your AVIF quality

    Choose a quality from 1–100 (around 60 by default) to balance file size against fidelity — higher for detailed photos, lower for maximum savings.

  3. 03

    Server encodes with AV1

    Our servers run the image through AV1 encoding, which analyzes it far more thoroughly than JPG — this is the CPU-intensive step that makes AVIF conversion slower than a simple format swap, though our optimized pipeline keeps it efficient.

  4. 04

    Download your AVIF

    Grab your AVIF, typically 30–60% smaller than the original JPG, from a secure signed link. The output file is deleted automatically within 24 hours.

Why choose our JPG to AVIF Converter

Smaller files at the same quality

AVIF's AV1 codec typically shrinks photos to 30–60% of their JPG size at comparable visual quality.

Optimized encoding pipeline

AV1 encoding is inherently more CPU-intensive than saving a JPG, but our libvips-based pipeline is tuned to keep conversion times efficient rather than instant.

Broad — but not universal — support

All modern browsers and recent operating systems display AVIF, though some older apps and editors can't open it yet, so keep that in mind for your use case.

Secure processing, auto-deleted

Files travel over encrypted HTTPS and are processed on our servers; converted AVIFs are deleted within 24 hours and original uploads within 6–24 hours.

Free to start

Anonymous visitors get 1 free server conversion, and a free account adds 3 more every 30 days.

No account required to try it

Convert your first JPG to AVIF without creating an account — sign up only when you need batch conversion or higher limits.

Settings guide

Quality (1–100)
Controls AV1 compression strength. The default of about 60 already looks close to the source JPG at a fraction of the size; raise it to 70–80 for detailed photos or lower it when the smallest possible file is the goal.

About the formats

JPG

JPG (also written JPEG) is the most widely used lossy image format for photographs, standardized by the Joint Photographic Experts Group in 1992. Practically every camera, phone, and image application can create and open it.

Its strengths are small file sizes for photos and universal compatibility across devices, browsers, and software. The trade-offs: lossy compression introduces artifacts, there is no transparency support, and quality degrades a little more with every re-save. Use JPG for photographs; choose PNG for screenshots, logos, or anything that needs sharp edges or transparency.

AVIF

AVIF is a modern, royalty-free image format based on the AV1 video codec, developed by the Alliance for Open Media. It is one of the most efficient web image formats available today.

AVIF combines excellent compression with alpha transparency, HDR, and wide color gamut support, and typically beats both JPG and WebP in file size at equal quality. Encoding is noticeably slower than other formats, and viewing requires a modern browser — older systems and many desktop apps cannot open it. Keep a JPG or WebP fallback when your audience may include legacy environments.

Troubleshooting

The conversion is slow
AV1 encoding is CPU-heavy by design, so high-resolution JPGs can take noticeably longer than other conversions. This is normal — leave the page open and the download will appear when the encode finishes.
My app can't open the AVIF file
Older image viewers, editors, and some email clients do not support AVIF yet. Update the app, open the file in a modern browser, or keep a JPG copy for tools that need it.
The output looks soft or blocky
Raise the quality setting — try 70–80. Very low values smooth away fine texture; also remember the source JPG's own artifacts cannot be recovered, so start from the best original you have.

FAQ

How much smaller will my file get?
AVIF uses the AV1 codec, and photos typically shrink to 30–60% of the JPG size at comparable visual quality. The exact saving depends on the image content and the quality setting (default around 60).
Will the AVIF open everywhere?
AVIF is supported by all modern browsers (Chrome, Firefox, Safari, Edge) and recent OS versions, but some older apps and image editors cannot open it yet. Also note that AVIF encoding is CPU-intensive, so large images take longer to convert.
Can I convert multiple JPGs to AVIF at once?
Yes, with an account. Free accounts can batch up to 5 files at a time, and paid plans support batches of up to 100 files. Anonymous visitors are limited to converting one file.
Should I use AVIF instead of WebP for my website images?
Often yes — AVIF's AV1 codec typically compresses 10–40% smaller than WebP at similar visual quality, which helps page-load performance and Core Web Vitals. The trade-off is slower encoding and slightly less universal support than WebP.
Why does converting to AVIF take longer than saving a JPG?
AVIF encoding uses the AV1 video codec's still-image profile, which analyzes each image far more thoroughly than JPG's compression. That extra analysis is what delivers the smaller file size, but it also means encoding takes noticeably longer than a quick format like JPG — or than decoding an existing AVIF back to JPG.
Are my files private?
Yes. Files are uploaded over an encrypted HTTPS connection and processed on our servers. Converted outputs are deleted automatically within 24 hours, and your original uploads are removed within 6–24 hours. We never share your images.
What are the size and usage limits?
Anonymous visitors can upload files up to 20 MB and get 1 free server conversion. A free account raises this to 50 MB per file, 3 free conversions every 30 days, and batches of up to 5 files. Paid plans allow 200 MB per file and batches of up to 100 files.
