HEIC Won't Open? Convert to WEBP Instantly
Fast, instant HEIC to WEBP conversion. No signup required. Just drop your .heic file and get .webp in seconds.
Batch Settings
HDR data will be tone-mapped
Your HEIC file may contain HDR (High Dynamic Range) data. WEBP only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Generation loss — quality may degrade
HEIC uses lossy compression and WEBP typically uses lossy mode. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Wide color gamut → sRGB
Your HEIC file uses a wide color gamut (Display P3, sRGB). WEBP uses standard sRGB. Highly saturated colors outside the sRGB range will be clipped or compressed — this is most noticeable in vivid reds, greens, and blues.
Default format on iPhone 7+ (iOS 11+)
Your device saves files in HEIC by default (iPhone 7+ (iOS 11+), iPad Pro 2017+, macOS High Sierra+). Most people convert because the files won't open on other devices — WEBP is universally supported and will work everywhere.

About HEIC to WEBP Conversion
Dealing with a HEIC file that won't open on your device? You're not alone — HEIC compatibility issues are one of the most common reasons people search for a file converter. HEIC (High Efficiency Image Container) is Apple's format for iPhone photos, offering twice the compression of JPEG.
The fix is simple: convert your HEIC to WEBP. WebP is Google's modern image format offering both lossy and lossless compression at 25-35% smaller sizes than JPG/PNG. This conversion lets you improve file compatibility across devices, solving the problem in seconds rather than hours of troubleshooting.
Full Name: HEIC uses High Efficiency Image Container, while WEBP uses WebP Image. Compression: HEIC uses Lossy, while WEBP uses Lossy & Lossless. Transparency: HEIC uses No, while WEBP uses Yes. Your HEIC file may contain HDR (High Dynamic Range) data. WEBP only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.

What Happens When You Convert HEIC to WEBP
Your HEIC image is decoded into raw pixel data, then re-encoded as WEBP.
Your HEIC file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
HDR data is tone-mapped to standard dynamic range (8-bit per channel)
Pixels are re-encoded using WebP Image's lossless compression
Metadata (EXIF, ICC profiles) is transferred where WEBP supports it
The WEBP file is saved and ready for download

Frequently Asked Questions
Why won't my HEIC file open?
HEIC files may not open if your device lacks the right codec or application. Converting to WEBP — a more widely supported format — usually resolves this. WebP is Google's modern image format offering both lossy and lossless compression at 25-35% smaller sizes than JPG/PNG.
Is it safe to convert HEIC to WEBP online?
Yes. CocoConvert encrypts your file via TLS, processes it on isolated servers in Germany, and permanently deletes it within 24 hours. Your files are never shared or analysed.
Will I lose quality converting HEIC to WEBP?
Your HEIC file may contain HDR (High Dynamic Range) data. WEBP only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost. CocoConvert uses high-quality encoder defaults to preserve as much fidelity as possible.
How large can my HEIC file be?
Free users can convert files up to 250 MB each. Pro users get a 5 GB limit per file, and Business API users have custom limits.
Can I convert HEIC to WEBP on my phone?
Absolutely. CocoConvert works in any modern browser — iOS Safari, Android Chrome, and all desktop browsers. No app required.
