If you're moving photos from an iPhone camera roll directly to a website, converting HEIC to WebP skips an unnecessary intermediate step. WebP is the modern web format: 25–35% smaller than an equivalent-quality JPEG, with full alpha-channel transparency and near-universal browser support (Chrome, Firefox, Edge, Safari 14+). For image-heavy pages, the payload difference is substantial — a gallery of 20 photos can easily be 4–5 MB lighter in WebP than in JPEG.
HEIC and WebP are both more efficient than JPEG, but their design goals diverge. HEIC is built for device storage with deep hardware integration in Apple's codec pipeline. WebP is built for web delivery — it's an open format that any browser can decode in software, without device-specific hardware acceleration. Converting from HEIC to WebP gives you the best-compressed format that works across all platforms without plugins or fallbacks.
The conversion runs entirely in your browser: the HEIC decoder unpacks Apple's format, and the Canvas API re-encodes the result as WebP. No file is uploaded, no account is needed. You can batch-convert an entire camera roll export and the individual files convert in parallel — one slow file does not hold up the others.
Frequently asked questions
WebP is 25–35% smaller than JPEG at the same visual quality, and it supports transparency — something JPEG cannot do at all. For web use, WebP is the better target in almost every scenario: smaller files mean faster page loads and better Core Web Vitals scores. JPEG is only preferable when you need guaranteed compatibility with very old software or email clients.
At 85% quality (the default setting), the quality difference is imperceptible for photos at normal viewing sizes. You can raise the quality slider toward 100 for near-lossless output at the cost of a larger file. Note that this tool converts in two steps — HEIC decode, then WebP encode — so there is one round of lossy recompression.
All major modern browsers support WebP natively: Chrome (since 2011), Firefox (since 2019), Edge, and Safari (since version 14, released 2020). Global coverage across web traffic is above 95%. WebP is safe to use on any public-facing website without JPEG fallbacks.
No. The entire conversion — HEIC decoding and WebP encoding — happens locally in your browser using a WASM-based decoder and the Canvas API. Your photos never leave your device. This is true even for large batches: each file is processed in memory and the result is downloaded directly to your machine.
