Frequently Asked Questions
- Can I open HEIC files on Windows?
- Not natively on older Windows versions. Windows 11 supports HEIC, but Windows 10 requires a codec extension. Converting to WebP ensures the file opens anywhere.
- Is WebP supported by all browsers?
- Yes. All major browsers — Chrome, Firefox, Safari, Edge — support WebP natively as of 2024.
- Will I lose quality converting HEIC to WebP?
- Minimal loss. Both formats are lossy, but Convertify converts at high quality settings by default.
- What's the difference between HEIC and WebP file size?
- Both achieve similar compression. HEIC may be slightly smaller, but WebP is universally supported — making it the better choice for web use.
- Can I convert multiple HEIC files to WebP at once?
- Yes. Convertify supports batch conversion — upload up to 10 files and download them all as WebP.
- Does HEIC support transparency?
- Yes, HEIC supports alpha channels. WebP also supports transparency, so it is preserved during conversion.
- Is Convertify free to use?
- Yes, completely free. No signup, no watermarks, no limits on conversions.
What is HEIC?
HEIC (High Efficiency Image Container) is Apple's default photo format since iOS 11. It achieves roughly 50% better compression than JPG at similar quality — great for iPhone storage, but a problem the moment you share outside Apple's ecosystem.
Why convert HEIC to WebP?
WebP is the most practical modern format for web use. If you have HEIC photos from your iPhone and need to use them on a website, in a web app, or share them via a platform that does not accept HEIC, WebP gives you smaller files than JPG with better browser support than HEIC. All modern browsers support WebP natively — Chrome, Firefox, Safari, Edge, and Opera. HEIC has no browser support outside Safari on Apple devices.
WebP vs HEIC: browser and app support
HEIC is optimized for on-device storage on Apple hardware. WebP is optimized for web delivery. HEIC files cannot be displayed in browsers outside Safari. WebP works in every modern browser and is accepted by most web platforms, CDNs, and CMS systems including WordPress. For web developers and content creators working with iPhone photos, converting HEIC to WebP is the most efficient path to web-ready images.
File size after converting HEIC to WebP
Both HEIC and WebP use efficient modern compression. File sizes after conversion are comparable — WebP typically produces files similar in size to HEIC at equivalent quality. In some cases WebP may be slightly larger for photographs, since HEIC uses HEVC which is one of the most efficient codecs available. The primary reason to convert HEIC to WebP is compatibility, not compression gains. You get web-ready files that work everywhere without the Apple ecosystem restriction.
How Convertify converts HEIC to WebP
Convertify uses a Rust backend with libvips — one of the fastest image processing libraries available. Conversion happens server-side in milliseconds. Your file is never stored permanently and is deleted immediately after download.
