Format comparison
AVIF (AV1 Image File Format) is a modern image format that targets high compression efficiency while preserving quality. Depending on the environment, encoding/decoding can feel heavier than older formats.
Pros
- ✓ Strong compression efficiency
- ✓ Can support HDR / wide color in supported pipelines
- ✓ Transparency support
Cons
- ✗ Slow encoding
- ✗ Limited browser support
WebP is a web-focused image format that often achieves smaller files while keeping good visual quality.
Pros
- ✓ Often smaller for web delivery
- ✓ Transparency support (useful for UI assets)
- ✓ Broad browser support
Cons
- ✗ Some older browsers unsupported
- ✗ Limited editing software support
When to Convert AVIF to WebP
Convert AVIF to WebP as a fallback for platforms that don’t support AVIF. WebP is a solid compatibility option for the web.

Technical details
AVIF is a modern image format often used for web optimization. It can be very efficient for photos, but performance and support vary across browsers and apps.
Good for
- Web delivery: Smaller files on supported platforms- Photos: Keeping quality while reducing size
Notes
- Performance: Encoding/decoding can feel heavier (split large batches when needed)- Compatibility: Not every environment can open AVIF — keep WebP/JPEG fallbacks if required

WebP Technical Specifications
Technical details
WebP is a web-focused image format that supports both lossy and lossless modes, and it can store transparency.
Good for
- Web delivery: Balancing file size and visual quality- Transparent assets: Often lighter than PNG in many cases
Notes
- Editing: Support varies across software- Compatibility: Some older environments may not support WebP
Reference: Google Developers: WebP
How to Use

Drop or click to select your AVIF files (multiple supported)
Confirm output
Default is WebP. You can change to another supported output format if needed.
Adjust options
Set quality, resize, and metadata options only if you need them.
Convert & download
Download each file, or download everything as a ZIP for batch outputs.
FAQ
Why convert AVIF to WebP?
Useful as a fallback for older browsers, social platforms, and CMSs that don't support AVIF. WebP has broader compatibility.
Will file size increase?
WebP files are usually slightly larger than AVIF but still smaller than PNG or JPEG -- a practical middle ground.
How much quality is lost?
Lossy-to-lossy re-encoding causes some degradation. Quality 90+ keeps it virtually imperceptible.
Can I keep Exif metadata?
When "Keep Exif/Metadata" is ON, we try to carry over things like capture time, camera info, and GPS where possible. Some tags may be dropped depending on the input, output format, and browser environment. Turn it OFF if you want to remove location data before sharing.
Can I convert multiple files at once?
Yes. You can select multiple files, convert them in one run, and download each file individually. For multiple outputs, you can also download everything as a ZIP. For very large batches, splitting into smaller runs is more stable.
Are my images uploaded to a server?
No. Conversion runs locally in your browser, and your images are not sent to an external server.
What if conversion fails or is slow?
Some formats (like HEIC/HEIF) depend on browser support. If it fails, try another browser, reduce the number of files, or resize before converting.
Why do colors sometimes shift after conversion?
Differences in decoding/encoding and color handling can cause small shifts. For critical images, compare the output against the original.
