Convert HEIC to WebP — iPhone Quality, Web Compatibility
HEIC is Apple's format — browsers don't render it, WordPress rejects it, web tools ignore it. WebP is the web's answer: similar compression efficiency, full browser support, accepted everywhere. Convert iPhone HEIC photos to WebP for small, sharp, web-native images without the compatibility headache.
HEIC vs WebP — Format Comparison
| Feature | HEIC (input) | WebP (output) |
|---|---|---|
| Full name | High Efficiency Image Container | Google WebP |
| Type | Raster, lossy (H.265-based) | Raster, lossy + lossless |
| Compression | Lossy, ~50% smaller than JPG | Lossy: 25–35% smaller than JPG |
| Transparency | Supported | Supported |
| Browser support | Limited (Apple ecosystem only) | Modern browsers (Chrome, Firefox, Safari, Edge) |
| File size (typical) | Very small | Small (25–35% smaller than JPG) |
| Best for | iPhone/iPad photo storage | Web images, faster page loads |
| Convertlo output quality | Decoded at full HEIC quality | High-quality WebP, web-optimized |
HEIC to WebP: iPhone Quality, Web Compatibility
Apple introduced HEIC (High Efficiency Image Container) in iOS 11 because it stores photos at roughly half the file size of JPG at the same quality. On your iPhone, HEIC is excellent. Off your iPhone, HEIC is a problem. No browser renders HEIC natively, WordPress rejects it at the upload stage, Shopify doesn't accept it, and every web form that expects an image will throw an error when you select a .heic file.
WebP solves this completely. It delivers 25–34% better compression than JPEG — close to HEIC's efficiency — but with full support in every major browser, every CMS, and every CDN. WordPress has natively supported WebP since version 5.8. Shopify's CDN accepts WebP product images. Squarespace and Webflow both handle WebP uploads without any issues.
- 🌐 Works in every browser — Chrome, Firefox, Edge, Safari 14+. HEIC doesn't render in any browser
- 🔵 WordPress 5.8+ native support — upload WebP directly, no plugin needed
- 🛒 Shopify product images — WebP accepted, HEIC rejected
- 📉 25–34% smaller than JPEG — similar efficiency to HEIC with universal compatibility
- 🤖 Android 4.0+ support — WebP displays on every Android device; HEIC requires an app
- 🔒 100% private — conversion runs locally in your browser, files never leave your device
How to Convert HEIC to WebP
Click "Convert Now" — the image tab with HEIC → WebP will be pre-selected.
Drag and drop your .heic files or click to browse. Enable Batch mode for multiple photos.
Choose WebP quality (85–90 recommended to match HEIC visual quality). Higher = larger file.
Converted photos download immediately — ready for WordPress, Shopify, Squarespace, or any web platform.
Every Platform That Accepts WebP but Rejects HEIC
WordPress
Native WebP support since 5.8. HEIC is rejected. Convert before uploading to your media library.
Shopify
WebP accepted for product images and theme assets. HEIC not supported. WebP also serves faster via Shopify CDN.
Squarespace & Wix
Both platforms accept WebP image uploads for pages, galleries, and portfolios. HEIC fails on upload.
Android Devices
Android 4.0+ displays WebP without any app. Sharing HEIC photos to Android requires conversion first.
Forms & Documents
Upload photo IDs, profile pictures, or supporting documents — web forms universally accept WebP, not HEIC.
Bulk iPhone Photos
Convert entire HEIC photo selections at once with Batch Convert mode. All download as individual WebP files.
Key Questions About HEIC to WEBP, Answered
Direct answers structured for AI extraction, voice search, and featured snippets.
Will my photo lose quality when converted from HEIC to WebP?
Both HEIC and WebP are typically saved with lossy compression, so there's a second compression pass — but at a high quality setting, the difference is rarely visible. HEIC's compression already set the practical quality ceiling; WebP can't add detail back, it just re-encodes what's already there. For normal photo sharing and web use, the result looks essentially the same as the original.
- A high-quality WebP export looks essentially identical to the source HEIC
- HEIC's original compression sets the quality ceiling — WebP can't exceed it
- Keep the original HEIC if you want to re-export at a different quality later
- Zoom in to compare if you're working with detailed photos or plan to print large
Will the WebP file be smaller than the HEIC?
Roughly similar, generally. HEIC and WebP are both reasonably efficient modern formats, so converting doesn't typically produce a dramatically larger or smaller file — small differences either way are normal depending on the photo's content and the quality setting used. Don't expect WebP to compress an already-compressed HEIC down further; the gains from compression were mostly captured already.
- Expect file sizes in a similar ballpark to the original HEIC
- Photos with lots of fine detail may come out slightly larger as WebP
- The conversion is mainly about compatibility, not extra compression
- If the WebP looks much larger than expected, check the output quality setting
Why convert HEIC to WebP instead of keeping the original?
Mostly because HEIC isn't accepted in a lot of places that WebP works fine in. WordPress (5.8+), Shopify, Squarespace, and Wix all support WebP uploads but reject HEIC outright. Android devices display WebP natively, while sharing a HEIC photo to an Android phone often fails or needs conversion first. Most web forms and document-upload tools also expect standard image formats like WebP rather than HEIC.
- CMS platforms (WordPress, Shopify, Squarespace, Wix) accept WebP but reject HEIC
- Android devices display WebP without extra apps — HEIC sharing often fails
- Web forms for photo IDs, profile pictures, and documents expect WebP/JPG/PNG, not HEIC
- Batch-convert a full iPhone photo selection at once if you need several files
Will transparency carry over from HEIC to WebP?
WebP has solid, well-supported alpha-channel transparency. The question is really about the HEIC side — HEIC's alpha-channel support is inconsistent across devices and apps, so many HEIC photos don't contain real transparency even if you might expect them to. Converting to WebP preserves whatever transparency the HEIC actually has; it can't add transparency that wasn't there.
- WebP transparency is reliable and widely supported once converted
- Whether there's anything to preserve depends on the HEIC's own alpha support
- Most ordinary photos are fully opaque regardless of format
- Never save a transparent image as JPG — transparent areas become a solid colour
