HEIC (High Efficiency Image Container) uses HEVC/H.265 compression to deliver 40–50% smaller file sizes compared to JPEG at equivalent visual quality. Standardized by MPEG in 2015 and adopted by Apple in iOS 11 (2017), HEIC supports 8–10-bit color depth, HDR metadata, and image sequences. Files store efficiently but require modern decoders—native support is limited to iOS 11+, macOS High Sierra+, Android 10+, and Windows with extensions.

HEIC is ideal for iPhone users who want maximum storage efficiency without visible quality loss. While Apple devices handle HEIC natively, sharing with Windows PCs or older Android devices often requires conversion for compatibility.
WebP is Google's modern image format offering both lossy and lossless compression modes, plus alpha transparency and animation support—essentially combining the best features of JPEG, PNG, and GIF. Announced in 2010, WebP typically delivers 25-35% smaller files than JPEG at comparable quality using VP8 or VP8L compression. All major browsers now support WebP, making it a practical choice for web optimization.

WebP strikes an excellent balance between compression efficiency and ecosystem maturity. It's widely adopted for web delivery, supported across all modern browsers (Chrome 32+, Firefox 65+, Safari 14+, Edge 18+), and offers better compression than JPEG/PNG without the encoding overhead of AVIF.
CMS support: WordPress 5.8+ (July 2021) supports WebP natively. Most modern CMS platforms and CDNs (Cloudflare, Akamai, Fastly) can automatically serve WebP to compatible browsers via content negotiation.
Email limitation: Most email clients (Outlook, Gmail web, Apple Mail) do not support WebP. Always use JPG or PNG for email images, or provide a JPG fallback via <picture> elements in HTML emails.
Frequently Asked Questions
Why does my iPhone save photos as HEIC?
Why choose WebP over JPG for HEIC photos?
Is WebP supported in all browsers?
Yes. WebP is supported by 93% of global browsers as of 2025:
- Chrome: Since 2014 (version 32)
- Firefox: Since 2019 (version 65)
- Safari: Since 2020 (version 14 / iOS 14)
- Edge: Since 2018 (version 18)
The only notable exception is Internet Explorer (discontinued June 2022). For legacy support or maximum compatibility, use our HEIC to JPG converter—JPG works everywhere.
Is HEIC to WebP a lossy or lossless conversion?
How much smaller will my WebP files be compared to HEIC?
What happens to photo metadata and transparency?
Can I convert Live Photos or HEIC bursts?
Yes, but only the primary still frame converts. HEIC files can contain multiple types of data:
- Live Photos: Motion video discarded; only the still frame converts to WebP
- Burst sequences: Each HEIC file converts individually; the burst relationship isn't preserved
- HDR metadata: Wide color gamut converted to 8-bit sRGB (WebP limitation)
- Depth maps: Portrait mode depth data discarded (not supported in WebP)
What IS preserved:
- Image quality: High-fidelity WebP quality 85 encoding
- Orientation: Photos display right-side-up automatically
- Transparency: Alpha channels preserved (if present)
Does WordPress support WebP?
Yes. WordPress has supported WebP natively since version 5.8 (July 2021). After converting your HEIC photos to WebP, you can upload them directly to WordPress without plugins.
- Native support: WordPress 5.8+ handles WebP uploads, resizing, and thumbnail generation
- CDN integration: Cloudflare, Fastly, and most CDNs can auto-serve WebP to compatible browsers
This makes HEIC → WebP ideal for iPhone photos destined for WordPress sites.
Can I use WebP images in emails?
No, not reliably. Most email clients (Outlook, Gmail web, Apple Mail, Yahoo) do not support WebP images.
Recommendation: If you need HEIC photos for email, use our HEIC to JPG converter instead—JPG is universally supported in email clients.
What are the limits for this converter?
| Tier | Max File Size | Max Files/Batch | Parallel Processing |
|---|---|---|---|
| Guest/Free | 50 MB | 50 files | 3 at once |
| Pro | 1024 MB | 1000 files | 6 at once |
Note: File size limits are specific to this converter. Batch and parallel processing limits apply to all images converters site-wide. See all converter limits →
How are credits calculated for this conversion?
Cost: 1 credit per 10 MB
How it works:
- Files up to 10 MB: 1 credit
- 11-20 MB: 2 credits
- 21-30 MB: 3 credits
- 31-40 MB: 4 credits
Example: A 5 MB photo = 1 credit. A 95 MB photo = 10 credits.
Why per-megabyte? Larger files require more resources (processing, bandwidth, storage).
What are my daily and monthly credit limits?
Credit allocations vary by account tier:
| Tier | Daily Limit | Monthly Limit |
|---|---|---|
| Guest | 100 credits/day | — |
| Free | 100 credits/day | — |
| Pro | — | 12,000 credits/month |
Daily credits (Guest & Free tiers) reset every day at midnight UTC. Monthly credits (Pro) reset on your billing cycle date.
Note: With 1 credit per 10 MB, iPhone photos under 10 MB cost 1 credit each. Pro users can convert 12,000 iPhone photos per month.
