Transparency
The target can store an alpha channel, but converting an opaque image does not create transparent areas. Removing a background is a separate editing step.

What happens when you convert JPEG to AVIF?
Encoding mode
AVIF can use lossy or lossless AV1 coding. Chroma subsampling, RGB↔YUV conversion and reduced bit depth can change source values even when the AV1 coding stage is lossless. Quality defaults to 55; adjust it in Advanced options. File size depends on the image and encoder.

Compression: LossyTransparency: NoMetadata: Exif, ICC
A familiar format for photographs. JPEG keeps files compact by trading a little image detail for broad compatibility.

AV1 Image File Format
Compression: Lossy & losslessTransparency: YesMetadata: Exif, XMP, ICC, CICP
AV1-compressed pictures in an image container, with optional alpha, sequences and high-dynamic-range colour.

Good choice when
- AVIF fits your delivery use: Photo delivery & HDR images.
- Your receiving application supports the required AVIF variant.
- You can validate the destination’s sample precision and colour interpretation.
- You need a AVIF-compatible workflow that can hold transparency added in a separate edit.
Probably not when
- You need a guaranteed output file size or archival pixel equality. Encoder settings do not guarantee either.
- You require identical samples without a defined colour and precision policy.
- You expect automatic background removal or transparency.
JPEG to AVIF conversion details
- Transparency
- The target can store an alpha channel, but converting an opaque image does not create transparent areas. Removing a background is a separate editing step.
- Encoding mode
- AVIF can use lossy or lossless AV1 coding. Chroma subsampling, RGB↔YUV conversion and reduced bit depth can change source values even when the AV1 coding stage is lossless. Quality defaults to 55; adjust it in Advanced options. File size depends on the image and encoder.
- Sample precision & colour
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
- Metadata & colour
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
- Compression
- JPEG: Lossy → AVIF: Lossy & lossless JPEG: Typical JPEG files are lossy. The original standard also defines a separate lossless mode; it is not the usual web or camera JPEG. AVIF: AVIF can use lossy or lossless AV1 coding. Chroma subsampling, RGB↔YUV conversion and reduced bit depth can change source values even when the AV1 coding stage is lossless.
- Transparency
- Transparency is replaced with white by default. Change the background in Advanced options.
- Animation
- Still image output. Animated files use only the first frame; animation is not preserved.
- Colour depth
- AVIF: 8 / 10 / 12 bits
- HDR
- AVIF: Optional; colour properties
- Dimensions
- Rendered image dimensions are retained within the converter limits; this tool does not offer resizing. Orientation handling depends on the source decoder.
- Metadata
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
Common questions
Will the background become transparent?
The target can store an alpha channel, but converting an opaque image does not create transparent areas. Removing a background is a separate editing step.
Which compression mode will AVIF use?
AVIF can use lossy or lossless AV1 coding. Chroma subsampling, RGB↔YUV conversion and reduced bit depth can change source values even when the AV1 coding stage is lossless. Quality defaults to 55; adjust it in Advanced options. File size depends on the image and encoder.
Are bit depth and colour values guaranteed to match?
Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
Will metadata and colour profiles be retained?
Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
