HEIC to WebP
Re-encode HEIC and HEIF camera-roll photos into web-deliverable WebP entirely in your browser tab, with a quality slider for size control and batch ZIP export, so personal iPhone photos never touch an external server.
What it does
- Decodes HEIC/HEIF locally and re-encodes to WebP in-browser
- Lossy WebP with a quality slider for size control
- Batch many photos at once, downloaded as a single ZIP
- Runs fully offline after load, files never leave the tab
HEIC to WebP is a web-publishing conversion, not a sharing one, and here it runs without any upload: your iPhone photos are decoded and re-encoded inside this browser tab, never sent to a server. Most people who search for this exact pair are developers, bloggers, and site owners who picked WebP on purpose because they want a compact file every browser can render natively for page speed and Core Web Vitals, or because a CMS flat-out rejected the HEIC upload. WebP is web-deliverable in a way HEIC is not, and you can get there without handing your camera roll to an unknown cloud.
What this conversion actually does (and does NOT do)
HEIC (a HEIF container coded with HEVC/H.265) and WebP are both modern compressed formats, so this is a re-encode between two lossy codecs, not an upgrade. HEVC is generally the more efficient of the two, so do not expect the WebP to be smaller than the original HEIC; depending on content and quality setting it can come out larger. The real payoff is compatibility, not compression. WebP is supported by all current major browsers and opens on Windows and Android, while HEIC is not rendered by most browsers and is awkward on Windows without an extension.
Because you are going from one lossy codec to another, this is generational (double) compression. Visible artifacts can creep into smooth gradients, skin and shadow detail, and fine textures like hair or foliage, so keep WebP quality high to minimize it. The output is always fully opaque, because the HEIC decoder produces solid pixels; ordinary iPhone photos have no transparency, so typical files lose nothing. If a HEIC holds several images (a burst, a Live Photo, or another multi-image container), only the first image is converted, and motion and extra frames are dropped. The image is decoded to raw pixels and re-encoded, so the WebP does not contain the original EXIF data, GPS location or capture date.
When to choose HEIC to WEBP vs the alternative
Choose WebP when you are publishing to the open web and need one format that displays everywhere without an extension. If you only need a universally accepted photo for a form, portal, or email rather than for a website, plain JPG (jpg/jpeg) is the simpler choice and the HEIC to JPG converter handles that. If you want the smallest possible web image and you control which browsers your audience uses, AVIF often beats WebP, but WebP remains a safe, broadly compatible modern target, which is why HEIC to WebP is a pragmatic default.
How to convert
- Drop one or many HEIC/HEIF photos into the tool. They are read locally, with no upload.
- The output format is pre-selected to WebP; HEIC is decoded entirely in your browser.
- Set the quality slider (default 85): higher values keep more detail, lower values give smaller files.
- Convert, then download a single WebP directly or, for multiple files, grab the batch as one ZIP.
No upload. It runs on your device.
Decoding happens in your browser with a HEIC decoder that ships with the page and runs in a background worker inside this tab. Your browser's own image encoder then writes the lossy WebP at the quality you chose. If the browser cannot produce lossy WebP, the tool falls back to a lossless WebP encoded by the site's WebAssembly image module, tells you so, and the quality setting no longer applies. Either way the file bytes stay in local memory and no network request is made for the image. This matters because HEIC almost always means personal iPhone family photos, the kind you should not be uploading to an unknown service to begin with. After the page loads once it works offline, there is nothing to delete because nothing was ever uploaded, and you can confirm all of it yourself by watching the DevTools Network tab stay silent while you convert.
No limits
Convert as many photos as you want in one batch, with no file-count cap and no fixed size cap (only your device's memory sets a practical limit), no watermark stamped on the output, no sign-up, and no ads. The download-all-as-ZIP path is not gated behind a paid tier.
Frequently asked questions
- Is converting HEIC to WebP lossy or does it reduce quality?
- It is a re-encode between two lossy codecs, so it is generational compression rather than a clean copy. Artifacts can show up in gradients, skin and shadow detail, and fine textures, so keeping the WebP quality high minimizes any visible loss.
- Will the WebP file be smaller than my original HEIC?
- Usually not, and that surprises people: HEVC is generally more efficient than WebP, so the converted file is often similar in size or larger than the source. You convert for compatibility and web delivery, not to shrink the file below HEIC.
- Why convert HEIC to WebP instead of JPG?
- WebP usually gives smaller files than JPG at comparable quality and displays natively in current browsers, which makes it a good fit for websites. If you specifically need a universal photo format for a form or email rather than for a website, JPG (jpg/jpeg) is the simpler pick.
- Does converting HEIC to WebP keep transparency?
- No. This converter always produces a fully opaque WebP, because the HEIC decoder it uses outputs solid pixels. Ordinary iPhone camera photos have no transparency, so typical HEIC files lose nothing.
- Are my photos uploaded to a server when I convert HEIC to WebP here?
- No. The HEIC is decoded in your browser by a decoder bundled with the page, and the WebP is encoded locally, with zero network requests for the image. You can verify this by opening the DevTools Network tab and watching it stay quiet while a conversion runs.
- Can I convert multiple HEIC files to WebP at once (batch)?
- Yes. Drop as many HEIC/HEIF files as you like and they are processed locally, then a single WebP downloads directly or the whole batch comes back as one ZIP. There is no file-count cap.
- Can I choose lossy or lossless WebP?
- The tool produces lossy WebP, with the quality slider controlling the size-to-quality balance. Lossless WebP is only used as an automatic fallback when your browser cannot encode lossy WebP; in that case a notice appears and the quality setting does not apply.
- Does WebP work in all browsers and on Windows?
- WebP is supported by all current major browsers and opens on Windows and Android, which is exactly why it is web-deliverable. HEIC, by contrast, is not rendered by most browsers and needs an extension to view on Windows.
- Will converting to WebP remove my photo's EXIF and GPS data?
- Yes. The photo is decoded to pixels and re-encoded, so the WebP does not carry the original EXIF data, GPS location or capture date. Keep the original HEIC if you need that information. To inspect or remove metadata in other photos, use the EXIF viewer and remover.
- What happens to a Live Photo or burst HEIC when converted to WebP?
- Only the first image in the file is converted to one static WebP. The motion clip and any extra frames are dropped.
- Should I use WebP or AVIF for my website images?
- If you want the smallest possible file and control which browsers your audience uses, AVIF often beats WebP. WebP is a safe, broadly compatible modern target, so it is a pragmatic choice for general web publishing.
- Can I convert HEIC to WebP offline?
- Yes. Once the page has loaded, the decoder and encoder are already in the tab, so the converter works without a connection. You can disconnect and keep converting.
