HEIC to WebP: the smallest way to put iPhone photos on the web
Your iPhone saves photos as HEIC (High Efficiency Image Container) because the files are tiny. But most websites, content management systems and many apps cannot accept HEIC uploads at all — WordPress, Shopify and Squarespace all refuse them. WebP is the fix: Google's royalty-free image format keeps most of HEIC's size advantage (25–34% smaller than JPEG at the same visual quality) while rendering in every current browser. Converting HEIC to WebP is how you take photos off your phone and put them on the web without bloating your pages.
Unlike most online converters, this one does the whole job inside your browser — decode the HEIC, re-encode to WebP at your chosen quality, done. Your photos never travel to a server, there are no daily limits, and batch conversion plus a single ZIP download make short work of a whole camera roll.
How to convert HEIC to WebP
- Drop your HEIC photos onto the page. One photo or dozens — batch is the normal way to work, since iPhone photo problems rarely come one at a time.
- Pick a WebP quality. 90% (Recommended) is visually identical to the HEIC original. Choose 80% for the smallest files for web pages, 98% when every pixel matters.
- Convert. Each photo decodes and re-encodes locally; a progress bar tracks the batch. Speed depends on your device's processor, not your internet — because nothing uploads.
- Download. Save WebPs individually or grab everything as one ZIP. Your original HEIC files are untouched.
WebP vs JPG for websites
For photos on the web, WebP beats JPG on every axis that matters: 25–34% smaller files at the same visual quality (Google's own measurements), which means faster page loads, better Core Web Vitals scores and lower bandwidth bills. It also supports transparency (alpha channel), which JPG cannot do at all. The only reason to pick JPG over WebP today is compatibility with ancient software — every browser released in the last several years renders WebP, with Safari on board since version 16. If you need the universal fallback instead, our HEIC to JPG converter makes that.
Batch convert iPhone HEIC photos to WebP
The typical job is not one photo — it is forty product shots, a wedding album, or a trip's camera roll that all need to become web-ready. Drop them all at once: each gets its own card with live status, failed files are reported individually without stopping the batch, and the ZIP button collects every finished WebP into one download. Quality applies uniformly, so set it once for the whole batch.
Convert HEIC to WebP without uploading anything
Server-side converters (the usual free tools) work by uploading your photos, converting them on someone else's computer, and promising to delete them later. For personal photos that is a trust decision you should not have to make. This tool decodes HEIC with a WebAssembly module and encodes WebP with your browser's native encoder — the entire pipeline runs on your device. Close the tab and nothing remains anywhere. It also means conversion speed depends on your hardware, not your upload bandwidth: a slow connection does not slow anything down.
Getting iPhone photos into WordPress, Shopify and other CMSs
Most content management systems reject HEIC uploads outright — you will see an "unsupported file type" error and no useful guidance. The workflow: convert your iPhone photos to WebP here first (quality 80–85 is the sweet spot for web publishing), then upload the WebPs. They are accepted everywhere JPG is, load noticeably faster, and — unlike HEIC — display inline for every visitor regardless of their device.
Frequently asked questions
Is this HEIC to WebP converter free?
Yes — free, no sign-up, no watermark, no daily conversion limits. Your browser does all the work, so there is no per-conversion server cost to pass on to you.
Are my photos uploaded to a server?
No. The HEIC decoding and WebP encoding both happen inside your browser via WebAssembly and native browser APIs. Your photos never leave your device.
Will the WebP look as good as my HEIC original?
At the recommended 90% quality, yes — visually identical. Technically the conversion is a re-encode (not bit-for-bit lossless), so we say "visually identical" rather than "lossless". At 98% even pixel-peepers will struggle to see a difference.
Can I convert many HEIC files at once?
Yes — batch is the primary workflow. Drop dozens of photos, watch each card's progress, and download everything as a single ZIP. Files that fail (damaged or misnamed files) are flagged individually without stopping the rest.
Which browsers support WebP images?
All current ones: Chrome, Edge, Firefox, Opera and Safari 16+. Safari 14–15 had partial support. If you need images for very old software, convert to JPG with our HEIC to JPG tool instead.
What quality setting should I choose?
90% for general use (recommended default). 80% when file size matters most — web pages, email attachments. 98% for archival or print-adjacent use where you want maximum fidelity.
Does it work on iPhone?
Yes — the page runs in mobile Safari and Chrome. Converting on the iPhone itself is handy, though large batches convert faster on a desktop.
Why not just switch my iPhone to shoot JPG?
You can (Settings → Camera → Formats → Most Compatible), but HEIC files are roughly half the size of JPGs, so you would fill your storage twice as fast. The better pattern: keep shooting HEIC and convert copies to WebP only when you need them for the web.
My converted WebP looks rotated. What happened?
iPhone photos store orientation as metadata rather than rotating pixels. The decoder honors the orientation flag, so output matches what you see in Photos. If a file was already mangled before upload, no converter can recover the intended rotation.
How is this different from HEIC to JPG?
Same engine and privacy model, different output: WebP files are 25–34% smaller than JPGs at equal quality and support transparency. Choose WebP for the web, JPG for maximum compatibility. Convert HEIC to JPG here.
Can I convert WebP back to JPG later?
Yes — our WebP to JPG converter handles that, also free and browser-local.
