How to use
- Drop your file(s) into the box above — or click it to browse.
- Conversion starts immediately; the tabs switch to a different output format. Adjust the quality slider to re-encode instantly.
- Click Download on each finished file — or Download all (.zip) for a batch. Nothing was uploaded at any point.
Who needs HEIC → WebP?
People publishing iPhone photos on the web: bloggers, shop owners photographing products, and developers filling a site's media library. The usual workflow converts HEIC to JPG first and lets the CMS make WebP later — a double lossy hop. Converting HEIC to WebP directly skips the JPG middleman, keeping one generation of compression instead of two.
Both formats are modern codecs — HEIC compresses with HEVC intra-frames, WebP with VP8 — so the output size stays close to the original, unlike a HEIC → JPG conversion where files typically grow 1.5–2×.
| HEIC | WebP | |
|---|---|---|
| Codec | HEVC intra-frame | VP8 (lossy) / custom (lossless) |
| Size vs JPG | ~50% smaller | ~25–35% smaller |
| Browser support | Effectively none | Universal since 2020 |
| Alpha channel | Yes | Yes — preserved by this tool |
| Typical home | iPhone camera roll | Websites and apps |
Two things to know before converting
- Safari can't create WebP. Its canvas API decodes WebP but does not encode it — run this conversion in Chrome, Edge or Firefox. (The JPG and PNG tabs work everywhere.)
- Metadata is stripped. The canvas re-encode drops EXIF — GPS location and capture date do not travel into the WebP. A privacy plus for publishing; keep the HEIC originals if you need the data.
When NOT to convert HEIC to WebP
- Photos for print, email or documents — those pipelines want JPG; WebP support outside browsers is still patchy.
- Uploading to platforms that re-encode (Instagram, most social media) — they will re-compress anyway; give them the highest-quality source.
- Archival — keep the HEIC master; export WebP copies per use.
