HEIC to WebP

Convert iPhone HEIC photos to WebP — 25-35% smaller than JPG at the same quality. Universal modern-browser support. Batch in-browser, no uploads.

Updated May 2026

No HEIC files yet

Drag in iPhone .heic or .heif photos. Conversion happens locally — your photos never leave the browser.

WebP is supported in 95%+ of modern browsers (Chrome, Safari, Firefox, Edge). For older email clients or legacy systems that don’t accept WebP, use the HEIC to JPG tool instead.

What it does

Convert iPhone HEIC photos to WebP — the modern web image format that’s typically 25-35% smaller than equivalent-quality JPG while looking visually identical. Best choice for sharing iPhone photos to a website, blog, or any context where page-load speed matters: WebP files load faster, save CDN bandwidth, and improve Core Web Vitals (the LCP score Google uses as a ranking signal).

WebP support has reached effectively universal modern- browser coverage: Chrome (since 2010), Firefox (since 2018), Safari (since 2020), Edge (always). Combined that’s 95%+ of global web traffic. The handful of exceptions (very old email clients, some legacy CMSes) are the same ones that don’t accept HEIC either, so if you’re starting from HEIC you’re already targeting modern contexts where WebP works fine.

The conversion is two-step: first heic2any decodes the HEIC into raw pixel data, then Canvas 2D re-encodes that as WebP via canvas.toBlob("image/webp"). Quality slider controls the WebP encoder’s output (default 80, sweet spot for photographic content). Everything runs locally — your photos never leave your device.

How to use it

  1. Drop or pick your iPhone .heic or .heif files. Multi-file is fine — they batch.
  2. Adjust quality. 80 (default) is the sweet spot — visually identical to original, ~30% smaller than JPG. Drop to 60-70 for thumbnails where smaller is more important than perfect detail. 90+ for portfolios or photography sites.
  3. Click Convert. Each HEIC decodes via heic2any, then re-encodes as WebP via Canvas.
  4. Download each WebP. Drop into your CMS, image gallery, or anywhere a modern browser will render it.

When to use this tool

  • Hosting iPhone photos on a website or blog where load speed matters (basically all sites).
  • Migrating an iPhone photo library to a more web-efficient format for storage or archival.
  • Pre-processing for a CDN where you pay per GB of egress.
  • Modern photo galleries (Lightroom Web, photographer portfolios) that accept WebP.

When not to use it

  • Email attachments — many email clients (especially older Outlook versions) still don't render WebP inline.
  • Print services / passport photos / official document submissions — they typically require JPG specifically.
  • Text messaging (SMS / iMessage to non-Apple devices) — JPG is more universally supported.
  • When you specifically need lossless quality — use HEIC to PNG instead.

Common use cases

  • Onboarding a colleague who needs the same calculation/conversion
  • Verifying a number or output before passing it on
  • Quick conversion during a typical workday
  • Pre-decision sanity-check on inputs and outputs

Frequently asked questions

Why WebP over JPG for HEIC conversion?
WebP achieves 25-35% smaller files at equivalent visual quality, supports proper alpha-channel transparency (JPG doesn't), and works in 95%+ of browsers. The only reason to pick JPG over WebP is destination compatibility (some legacy contexts).
What about AVIF?
AVIF is even smaller than WebP (~50% smaller than JPG) but encoder support is uneven and generally slower. Browser support is around 90% as of 2026. For the sweet spot of size + compatibility + speed, WebP wins for most use cases.
Will my photo look different from the HEIC?
At quality 80+, indistinguishable to the eye. WebP and HEIC are both modern lossy formats with different compression algorithms — at high quality both preserve photographic detail well. At very low quality (50-60) you might see different artifacts (WebP block artifacts vs HEIC's smoother degradation), but at typical web quality, the difference doesn't matter.
Why two steps (HEIC → PNG → WebP)?
Because heic2any only outputs JPG and PNG — WebP isn't in its API. Going through PNG (lossless intermediate) then WebP-encoding via Canvas adds no quality loss vs. direct conversion would (if it existed). The round-trip is fast — typical iPhone photo: ~2 seconds.
Will EXIF metadata survive?
No. The heic2any → PNG → Canvas → WebP pipeline strips EXIF at the Canvas step. For metadata-preserving WebP conversion, use a desktop tool like ImageMagick or libwebp's `cwebp` directly, which can read EXIF from a JPG sidecar.
Is my photo uploaded anywhere?
No. The whole pipeline runs in your browser. Open DevTools → Network during conversion and you'll see zero outbound requests.
