Format comparison
JPEG (Joint Photographic Experts Group) is the most widely used image format, ideal for photographs and images with gradients.
Pros
- ✓ Universal compatibility
- ✓ Adjustable compression
- ✓ Great for photos
Cons
- ✗ Lossy compression degrades quality
- ✗ No transparency 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 JPEG to AVIF
Convert JPEG to AVIF to reduce file sizes for modern environments—useful for web performance optimization and next-gen format testing.
Technical Format Details
JPEG Technical Specifications
Technical details
JPEG is a lossy format optimized for photos. Lower quality settings reduce file size, but can introduce artifacts around edges and text.
Good for
- Photos: Natural images with gradients- Sharing: Maximum compatibility
Notes
- Re-encoding: Repeated saves accumulate artifacts (use PNG for editing intermediates)- Transparency: Not supported
Reference: JPEG Committee
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 JPEG 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 visible difference between JPEG and AVIF?
At equivalent quality, they're virtually indistinguishable.AVIF is typically 30–50% smaller than JPEG.
Should I use AVIF for e-commerce product images?
Yes. Faster loading directly impacts conversion rates. Use <picture> tags with JPEG fallback for safety.
Does encoding take long?
AVIF encoding is heavier than JPEG or WebP, but typical photos finish in a few seconds to around 10 seconds.
Will converting reduce image quality?
It depends on the output format. PNG is lossless, so quality stays the same. Lossy formats like JPEG/WebP/AVIF/JXL can change file size and appearance depending on the quality setting. Always verify with the final output before publishing.
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.
