HEIC to WEBP Converter

1. Upload one or more HEIC files (up to 50 MB total).
2. Click 'Convert to WebP' — finishes in under 2 seconds per image.
3. Download WebP files individually, or grab all as a ZIP.

Both HEIC and WebP are modern formats — HEIC saves 40-50% vs JPG, WebP saves 25-35% vs JPG. Converting HEIC to WebP preserves small file size while gaining universal browser support (WebP works in every browser since 2020).

HEIC is Apple's format — great for iPhone photos, but not natively supported by most web browsers. WebP is Google's format — also efficient (25-35% smaller than JPG) and supported by Chrome, Firefox, Safari, and Edge since 2020. If you publish photos to the web, converting HEIC to WebP keeps files small while guaranteeing they display everywhere.

The converter decodes the HEVC-compressed HEIC image and re-encodes it as WebP using libwebp at 85% quality. WebP's VP8-based compression is comparable to HEIC's efficiency. Transparency from HEIC's alpha channel is preserved because WebP supports 8-bit alpha. EXIF metadata is preserved.

• Publishing iPhone photos on a WordPress blog or CMS.
• Preparing images for CDN delivery to reduce bandwidth costs.
• Uploading HEIC photos to web forms that accept WebP but not HEIC.
• Creating WebP assets for modern e-commerce sites.
• Reducing image weight for Core Web Vitals (LCP) optimization.
• Serving WebP with JPG fallback via <picture> element.
• Preparing images for platforms that prefer WebP for performance.

WebP output uses 85% quality — visually indistinguishable from the source HEIC at normal viewing distances. The output is typically 25-40% larger than the HEIC source (WebP is slightly less efficient) but 25-35% smaller than an equivalent JPG. Transparency is preserved, making WebP the best format for logos and UI images.

• WebP output is 25-40% larger than the HEIC source.
• Some older CMS platforms (pre-2018) reject WebP uploads.
• Very old software (Photoshop CS6, Windows Photo Viewer) may not open WebP.
• Animated HEIC sequences are converted using only the first frame.
• HEIC depth maps and Live Photo data are not preserved.

• WebP opens natively in every modern browser (Chrome, Firefox, Safari, Edge).
• Native support in Windows 10+, macOS Big Sur+, iOS 14+, Android 4+.
• Supported by WordPress 5.8+, Shopify, Squarespace, Wix, Ghost.
• Native import in Photoshop 23+, GIMP 2.10+, Affinity, Figma.
• Ideal for CDN delivery (Cloudflare, CloudFront support WebP).

• WebP is supported by every modern browser — safe for public websites.
• Serve WebP with JPG fallback via <picture> for maximum compatibility.
• Keep the original HEIC if you need the Apple-optimized version.
• For transparency, WebP is the best alternative to PNG (smaller file).
• Batch-convert up to 50 MB of HEIC files at once.

WebP file won't open in Photoshop CS6

Photoshop CS6 predates WebP support. Use Photoshop 23+ or convert WebP → JPG first.

WebP file is larger than expected

WebP output is typically 25-40% larger than the HEIC source, because WebP is slightly less efficient than HEVC-based HEIC. Still 25-35% smaller than JPG.

Website rejects WebP upload

Update your CMS to WordPress 5.8+ or add WebP support via plugin. If the platform is old, use JPG instead.
