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
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 JPEG to WebP
Convert JPEG to WebP to reduce page weight while keeping good visual quality—useful for image-heavy web pages.
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
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
Add files
Drop or click to select your JPEG 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
Is there a visible difference between JPEG and WebP?
At equivalent quality settings, they're virtually indistinguishable.WebP typically achieves the same look at a smaller file size.
Can I use this for e-commerce product images?
Yes. Major e-commerce platforms (Shopify, etc.) support WebP. Lighter product images improve page speed, which can boost conversion rates.
Should I keep the original JPEG?
Yes. Keep the original for future format changes or content updates. Always work from the highest-quality source available.
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.
