Format comparison
HEIC (High Efficiency Image Container) is a high-efficiency photo format commonly used on iPhone and iPad. It often produces smaller files, but compatibility varies across apps and platforms.
Pros
- ✓ Efficient compression for photos
- ✓ HEIF container features (metadata, sequences)
- ✓ Common default on Apple devices
Cons
- ✗ Compatibility can be limited in some apps/browsers
- ✗ May require extra codecs on some platforms (e.g., Windows)
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 HEIC to WebP
Useful for preparing iPhone photos for websites or blogs. WebP often reduces size while keeping broad browser compatibility.

Technical details
HEIC/HEIF is commonly used for photos on iPhone and iPad. It can keep file sizes smaller, but compatibility varies across Windows, browsers, and editing tools.
Good for
- On-device photo storage: Efficient photo saving- Keeping metadata: Managing capture info alongside the image
Notes
- Compatibility: You may need JPEG/PNG/WebP for sharing and uploads- Environment differences: Decoding and conversion behavior depends on browser/platform support

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

FAQ
Which browsers support WebP?
All major browsers — Chrome, Firefox, Safari, Edge — support WebP. Only IE11 lacks support, which is rarely a concern today.
Which is smaller, HEIC or WebP?
At similar quality, they're comparable, with HEIC sometimes slightly smaller.However, WebP is optimized for web delivery and has much broader browser support.
Can I use WebP on WordPress?
WordPress 5.8+ supports WebP uploads natively. You can add WebP images to the media library without any plugin.
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.
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.
