Format comparison
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
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
When to Convert WebP to AVIF
Convert WebP to AVIF to reduce sizes for modern environments. Check AVIF support on your target platform.
Technical Format Details
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

AVIF Technical Specifications
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
Reference: AOM: AVIF Specification
How to Use
Add files
Drop or click to select your WebP files (multiple supported)
Confirm output
Default is AVIF. 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
Is there a benefit to converting WebP to AVIF?
AVIF often produces files 20–30% smaller than WebP, with the greatest benefits for photographic images.
Is there quality loss from re-encoding?
Lossy-to-lossy re-encoding causes some degradation. Use higher quality settings and compare with the original.
Can all browsers display AVIF?
Chrome, Firefox, Safari, and Edge all support AVIF. It works in all major browsers except IE11.
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.
