How to Convert HEIC to WebP on Windows (No Upload)
Your iPhone shoots in HEIC. The modern web wants WebP — smaller, faster, supported everywhere. Here's how to turn a folder full of HEIC photos into web-ready WebP files on Windows, right inside your browser, without uploading a single byte.
Morphix HEIC → WebP Converter
Drop HEIC files, get WebP back. 100% local, batch supported, no signup.
Why WebP is the right target for the web
HEIC is Apple's compact iPhone format — fantastic on the phone, awkward off it. WebP is Google's modern image format, supported by every major browser, Windows Photos, Office, and every popular CMS (WordPress, Shopify, Squarespace, Webflow, Ghost). At similar quality it produces files 25–35% smaller than JPG, with optional transparency. For websites, e-commerce, blogs, and apps, WebP is the file format you want.
The 4-step bulk conversion
Select your HEIC files in File Explorer
Open File Explorer and find your iPhone photos folder. Hold Ctrl and click every .heic file you want to turn into WebP — select as many as you need.
Drag them into the Morphix converter
Open /convert/heic-to-webp in Edge, Chrome, or Firefox. Drag the selected files from File Explorer onto the drop zone. No upload starts — files stay on your PC.

Watch the local conversion happen
Morphix decodes each HEIC in your browser via WebAssembly and re-encodes it as a high-quality WebP. Open DevTools → Network to verify: zero upload requests.
Download your WebP batch
Save each WebP individually or grab the whole batch. Drop them straight into WordPress, Shopify, your portfolio, or any modern site for faster page loads.
HEIC vs WebP vs JPG: which should you pick?
HEIC wins on the iPhone — half the size of JPG at the same quality. Outside the Apple ecosystem it's a hassle. JPG is the universal fallback that opens literally everywhere, including 20-year-old software. WebP is the modern web standard: smaller than JPG, supports transparency, supported by every browser shipped in the last decade. For anything destined for a website or modern app, convert HEIC → WebP. For sending pictures to relatives who still use Windows XP, convert HEIC → JPG.
Why local conversion matters
Most online converters upload your photos to a remote server, convert them, and stream the results back. Even when the operator promises to delete files, your pictures have touched a stranger's disk — logs, backups, and operator access are all possible. For vacation snaps this is fine. For client photoshoots, ID scans, medical paperwork, or unreleased product shots, it's a real risk.
Morphix runs the entire HEIC → WebP pipeline inside your browser tab via WebAssembly. The Network tab in DevTools shows zero outbound requests during conversion. Your photos do not leave your PC.
FAQ
Why convert HEIC to WebP instead of JPG?
WebP files are typically 25–35% smaller than JPG at the same visual quality, support transparency, and load faster on websites. If your target is a website, blog, CMS, or modern app, WebP is the better choice. Pick JPG only when you need maximum compatibility with very old software.
Does Windows support WebP natively?
Yes. Windows 10 and 11 open WebP in File Explorer previews, Microsoft Edge, Chrome, Firefox, the Photos app, and modern versions of Office. No codec install is required, unlike HEIC.
Are my photos uploaded to a server?
No. Morphix decodes HEIC and encodes WebP entirely inside your browser tab using WebAssembly. Open DevTools → Network and you will see zero upload requests during conversion. Your photos never leave your PC.
Can I bulk convert a whole folder of HEIC files?
Yes. Drag a whole folder of .heic files from File Explorer onto the converter. There is no batch limit and no file-size cap because nothing is uploaded — the only ceiling is your computer's memory.
Will I lose quality going from HEIC to WebP?
Both HEIC and WebP are modern lossy formats with similar quality-per-byte. Morphix exports WebP at a high quality preset, so the visual difference is negligible while file sizes stay small.
Do I need admin rights or to install anything on Windows?
No. Morphix is a website, not a desktop program. It runs in any modern browser, requires no install, no registry changes, and no admin rights — it works on locked-down work or school laptops.
Does it work offline after the first visit?
Yes. Once the page and its WebAssembly decoder have loaded, you can disconnect from the internet and keep converting HEIC files to WebP locally with no network connection.
Can I upload the WebP results to WordPress, Shopify, or Squarespace?
Yes. All major CMS platforms accept WebP uploads, and most automatically serve them to modern browsers for faster page loads.
