JPG to AVIF Converter with Quality and Batch Controls
Convert JPG and JPEG images into compact AVIF files. Process a batch, adjust visual quality, compare output sizes, and download each AVIF or a ZIP.
No files selected
Your files are uploaded only when you start conversion and are not retained after the response is created.
How to convert JPG to AVIF
Upload JPG or JPEG files, choose AVIF quality, and convert the queue into modern AVIF images.
Upload JPG images
Choose up to 10 .jpg or .jpeg files, with a 20 MB limit per image.
Set AVIF quality
Choose a quality value from 20 to 100. The balanced default is 60.
Download AVIF files
Review source and output bytes, then download one file or the completed ZIP.
Choose AVIF quality and compression
AVIF quality controls the tradeoff between visible detail and output size. The original pixel dimensions stay unchanged.
| Control | Setting | Effect |
|---|---|---|
| AVIF quality | 20-100 | Balances file size against visible detail |
| Encoding effort | Balanced | Uses a practical speed and compression setting |
| Dimensions | Preserved | Keeps the source JPG width and height |
| Batch size | Up to 10 files | Converts multiple JPG and JPEG images in one queue |
JPG vs AVIF file size and quality
AVIF can represent similar visual quality in fewer bytes, but converting an existing JPG cannot recover detail already lost to JPEG compression.
| Characteristic | Source | Output |
|---|---|---|
| Codec | JPEG | AV1 Image File Format |
| Typical size | Small | Often smaller at similar visual quality |
| Transparency | Not supported | Supported by the format, though JPG sources are opaque |
| Compatibility | Nearly universal | Modern browsers and newer applications |
| Source quality | May already contain JPEG artifacts | Does not remove or recover existing JPG artifacts |
What to expect from AVIF output
The converter decodes the JPG pixels and creates a new AVIF file with a valid HEIF/AVIF container.
Valid AVIF encoding
The output is encoded as AVIF, not renamed from JPG.
Smaller is not guaranteed
Simple or already optimized JPG images can sometimes be smaller than their AVIF result.
No account required
The conversion endpoint does not require sign-in for files within the published limits.
Metadata is removed
The output focuses on visible pixels and does not preserve EXIF, GPS, comments, or embedded profiles.

JPG to AVIF FAQ
How do I convert JPG to AVIF?
Upload one or more JPG or JPEG images, choose AVIF quality, then select Convert to AVIF and download the completed files.
Is JPG to AVIF conversion free?
Yes. You can convert batches within the displayed file count and size limits without creating an account.
Can I batch convert JPG files to AVIF?
Yes. Add up to 10 JPG or JPEG files and download individual AVIF results or one ZIP archive.
Is AVIF smaller than JPG?
AVIF is often smaller at comparable visual quality, but the result depends on image content, source compression, and the selected quality.
Does converting JPG to AVIF improve quality?
No. AVIF can encode the visible pixels efficiently, but it cannot restore detail discarded when the JPG was created.
What AVIF quality should I use?
Start at 60 for a balanced result. Increase it for fine detail or lower it when file size matters more.
Are my JPG images uploaded?
Yes. Files are sent to this site's conversion endpoint, processed for the response, and not retained by the endpoint.
Which browsers support AVIF?
Current Chrome, Edge, Firefox, and Safari releases support AVIF. Older operating systems and image editors may require JPG instead.
Can I convert JPEG to AVIF too?
Yes. JPG and JPEG use the same format, and both extensions are accepted by this converter.
