How to Convert HEIC to WebP

Converting iPhone HEIC photos directly to WebP gives you the best web-ready format — WebP is 25-35% smaller than JPG at equal quality, supports transparency, and has 97%+ browser support. This is a better workflow than HEIC → JPG → WebP since it avoids double re-encoding.

Step-by-step instructions

  1. 1

    Method 1: Browser converter (single step)

    Go to formatdrop.com → Image Converter. Drop your HEIC file. Select WebP output. Set quality (85% is ideal). Download. The converter decodes HEIC and encodes to WebP in one step — no intermediate JPG quality loss.

    Method 2: FFmpeg

    ffmpeg -i input.heic -q:v 85 output.webp. Or for specific WebP options: ffmpeg -i input.heic -vf scale=-1:1080 output.webp (resize to 1080px height while maintaining aspect ratio). FFmpeg requires libheif support for HEIC decoding — install on Mac with 'brew install ffmpeg' (includes libheif).

  3. 3

    Method 3: macOS sips (Mac command line)

    macOS includes 'sips' (Script Image Processing System): sips -s format webp input.heic --out output.webp. Batch convert: for f in *.heic; do sips -s format webp "$f" --out "${f%.heic}.webp"; done

  4. 4

    Method 4: ImageMagick

    magick convert input.heic -quality 85 output.webp. ImageMagick handles HEIC via libheif. Batch: magick mogrify -format webp -quality 85 *.heic

Why convert HEIC to WEBP?

The modern web image stack: shoot in HEIC (best quality on iPhone), convert to WebP for web delivery (best compression-to-quality ratio for browsers), use JPG as fallback for older browsers and email. HEIC and WebP are both based on video codec technology (HEVC and VP8/VP9 respectively) — both achieve dramatically better compression than JPG. Converting directly from HEIC to WebP without an intermediate JPG step produces the best output quality.

Your files never leave your device

Frequently asked questions

Is it better to convert HEIC to WebP or to JPG?
For web use: WebP is better — 25-35% smaller than JPG at equal quality. For email and legacy applications: JPG is better — universally compatible. For maximum workflow simplicity: convert to JPG (works everywhere). For a modern website where you control the serving environment: convert to WebP for smaller files and better performance.
Will converting HEIC to WebP lose quality?
Both HEIC and WebP are lossy formats. Converting involves decoding HEIC to raw pixels, then re-encoding to WebP. At WebP quality 85%: the output looks excellent and is virtually identical to the HEIC source at normal viewing sizes. Keep the original HEIC files as archives.
