HOW TO CONVERT HEIC → WEBP
Drop the HEIC file
Drag and drop or click to upload your HEIC. The image is transferred securely over HTTPS and queued for conversion.
Re-encode with ImageMagick
ImageMagick decodes every pixel of the HEIC and writes a matching WEBP with sensible default quality settings.
Download the WEBP
The converted WEBP is ready to download as a single file; both files delete automatically within two hours.
HEIC files shot on an iPhone or iPad encode each frame with HEVC (H.265) intra-coding, a codec designed for video that packs extraordinary dynamic-range detail into small files but requires Apple-specific decoding libraries that most browsers, Windows versions before build 17763, and virtually every web server simply do not have. WebP, developed by Google and built on the VP8 lossy codec or a lossless variant based on WebP Lossless, is natively decoded by every major browser released since 2020, by Android, by Windows 10 and 11 through built-in Edge rendering, and by modern Linux desktops without any additional codec installation. Converting HEIC to WebP turns a proprietary still image into a universally readable file that typically stays within 15 to 30 percent of the original HEIC file size under comparable quality settings, making it the practical choice for web publishing, sharing outside the Apple ecosystem, or embedding images in tools that rely on browser rendering engines.
Why convert HEIC to WEBP
The core driver is codec lock-in. HEIC wraps one or more HEVC-encoded still images in an ISOBMFF container, and decoding that stream requires either Apple's proprietary CoreImage framework or a third-party HEVC library like libde265. Android apps that have not bundled an HEVC decoder, Windows installations without the HEVC Video Extensions codec purchased from the Microsoft Store, and every web browser on every platform reject HEIC outright or silently fail to render it. WebP removes that dependency entirely: the format uses a well-documented open codec, carries no patent licensing friction, and decodes in every Chromium-based browser, Firefox, Safari 14 and later, and the WebView component embedded in mobile apps. The practical result is that the same image becomes usable in any drag-and-drop upload form, any CMS, any email client that renders inline images through a browser engine, and any social platform that inspects file headers before accepting uploads.

HEIC vs WEBP — Strengths and limitations
What each format does best, and where it falls short.
HEIC Strengths
- Roughly 50% smaller than JPEG at equivalent visual quality.
- 10- and 12-bit color depth supports HDR photography.
- Container format holds depth, Live Photo, bursts, and thumbnails in one file.
- Supports transparency and multi-image sequences.
- Built into iOS, macOS, and most modern Samsung and Google flagships.
Limitations
- Patent-encumbered (HEVC) — Windows users must buy a $0.99 codec pack from the Microsoft Store.
- Not supported by most web browsers or older image editors.
- Sharing to non-Apple platforms usually auto-converts to JPEG, losing metadata.
WEBP Strengths
- Smaller file sizes than JPEG, PNG, and GIF at equivalent visual quality.
- Single format for lossy photos, lossless graphics, transparency, and animation.
- Full alpha channel support with smaller files than PNG.
- Now universally supported in all modern browsers.
- Open-source reference implementation (libwebp) by Google.
Limitations
- Some older software and image editors still don't read WebP natively.
- Max dimensions are 16,383 × 16,383 — lower than JPEG or PNG.
- Print workflows rarely support WebP (no CMYK, limited color management).
Quality & Compatibility
HEIC can encode in 8-bit or 10-bit per channel, preserving the extended dynamic range that iPhone cameras capture in HDR mode. WebP lossy is limited to 8 bits per channel in the YCbCr 4:2:0 color space, so a 10-bit HEIC will be tone-mapped to 8-bit during conversion and the highlight headroom recorded by the sensor is permanently discarded. WebP lossless operates in RGBA at 8 bits per channel and preserves pixel-exact values, but lossless WebP files of photographic content run larger than lossy WebP at quality 80 and above, so lossless is rarely the right choice for camera photos. HEIC supports an alpha channel for Portrait mode depth-based compositing but the alpha is stored as a secondary auxiliary image track, not interleaved; WebP supports a true RGBA alpha channel both in lossy and lossless mode, so if the converter correctly extracts the HEIC auxiliary alpha and writes it into the WebP RIFF chunk, transparency survives. Exif and XMP metadata blocks embedded in the HEIC ISOBMFF container can be re-embedded in the WebP file's EXIF and XMP chunks during conversion; ICC color profiles can similarly be carried in the ICCP chunk, preserving the Display P3 profile that iPhones write, though few web renderers actually apply it. GPS coordinates, capture time, camera model, and lens data travel intact when those metadata chunks are copied; if the converter strips all metadata for privacy, that information is lost permanently.
Tips for Best Results
- If the HEIC was taken in HDR or on an iPhone 12 or later in Dolby Vision still mode, inspect the output WebP at 100 percent zoom before publishing — highlight clipping introduced by 10-bit to 8-bit tone-mapping shows as blown whites or crushed shadows that looked correct in the original.
- For web use, lossy WebP at quality 80 to 85 hits the best size-to-fidelity ratio for typical iPhone photography; going above 90 rarely saves visible detail compared to the original HEIC but pushes file size above what a well-tuned JPEG would produce at the same apparent quality.
- When converting a Live Photo HEIC (which stores the still frame plus a short video track in the same container), the converter will extract only the primary still image and discard the video component — the resulting WebP is a static file with no motion, which is expected and correct behavior.
Frequently Asked Questions
It depends on the codecs involved. If both HEIC and WEBP are lossy, the pixels are re-encoded and a small amount of detail is discarded — invisible at default quality settings on photographs. If WEBP is lossless (PNG, TIFF, BMP) the output keeps every pixel of the decoded HEIC exactly, but cannot recover detail that HEIC had already compressed away.
Often yes, especially when WEBP is lossless. HEIC tuned for efficient web delivery will usually produce smaller files than WEBP's default settings. If file size matters, drop the quality in Advanced or pick a more compressed target format instead.
KaijuConverter uploads over HTTPS, processes the image in an isolated container and deletes both the source and the output within two hours. No account is required, file contents are never logged, and we do not use uploads to train any model. For confidential material, the paid plan includes a data-processing agreement.
HEIC Image
Source formatHEIC is the default photo format on Apple devices since iOS 11. It offers roughly 50% better compression than JPEG at similar quality but has limited support outside the Apple ecosystem.
WebP Image
Target formatWebP is a modern image format developed by Google that provides superior lossless and lossy compression. Files are typically 25-35% smaller than equivalent JPEG or PNG images at the same visual quality.
