How to Convert HEIC to WebP (Smaller Files, Same Quality)

Yes — HEIC to WebP works, and it's the right move when you want the smallest possible file size for the same visual quality. WebP is typically 25–35% smaller than JPG at equivalent quality, and even smaller than HEIC for some content types.

Why convert HEIC to WebP

HEIC is great for iPhone storage. But once you want to use those photos on the web, in a blog post, or in an app, WebP is often the better target format:

3 ways to convert HEIC to WebP

1. Install Windows 11's free HEIF Image Extension

The HEIF Image Extension from Microsoft Store lets the Photos app open HEIC, but it does NOT save as WebP. You'd need an extra tool anyway, so this method is effectively not useful for HEIC to WebP.

2. Use an online HEIC to WebP converter

Websites like CloudConvert, Convertio, and Squoosh convert HEIC uploads to WebP downloads. They work for one-off files but every photo uploads to a server. Most cap file size at 25–100 MB — and WebP is specifically meant to be small, so uploading large HEIC files just to get smaller WebP back feels backwards. Your photos also sit on a stranger's server for hours.

3. Use EasyImg (desktop, local, batch)

EasyImg is a desktop app for Windows and Mac that converts HEIC to WebP entirely on your computer. Drag in a folder of iPhone photos, pick WebP, click Convert. A 12-megapixel HEIC converts in about half a second, and 200 photos finish in a couple of minutes. Quality defaults to 90 (visually identical to the source for most photos) with a slider if you need finer control. EXIF and color profiles are preserved by default. No upload, no queue, no file size cap, no internet required.

How to convert HEIC to WebP with EasyImg

1
Drop in your HEIC files

Single files, folders, or both. EasyImg reads HEIC natively — no Windows HEIF extension needed.

2
Pick WebP and set quality

Default 90 looks identical to the source at smaller file sizes. Lossy mode (default) is what most people want; EasyImg also offers lossless WebP if pixel-perfect output matters more than file size.

3
Click Convert

Files save with .webp extension. Duplicates skipped, filename conflicts auto-rename.

HEIC to WebP — common questions

JPG is the universal format. WebP is the modern web format. JPG opens on every device, period. WebP opens on every modern browser and most modern apps, but a few legacy systems still don't recognize it. If your photos are for the web (a blog, an app, a portfolio), WebP gives you the same visual quality at a noticeably smaller file size. If your photos are for printing, sharing with non-tech friends, or uploading to a system that doesn't accept WebP, use HEIC to JPG instead.
WebP is typically 25–35% smaller than JPG at equivalent visual quality. Compared to HEIC, the comparison is closer — for photos, WebP at quality 80 is roughly the same size as HEIC at default, while WebP at quality 90 is about 10–20% larger than HEIC but visually lossless. The advantage of WebP over HEIC is universal browser support.
Yes — both iOS 14+ and modern Android open WebP in Photos / Gallery apps. WebP is the default image format Google's Chrome and YouTube have shipped for years, and Apple added support in Safari 14 (released 2020). For web display, you're safe; for cross-platform photo sharing, JPG is still safer for very old devices.
WebP supports both. The default mode in EasyImg is lossy (smaller files, indistinguishable from the source at quality 90+). Lossless WebP preserves every pixel exactly — file size is about 3–5× larger than lossy but still smaller than PNG. For most web use, lossy WebP is the right choice. Pick lossless when you need pixel-perfect output (logos, graphics, master files).
EasyImg preserves EXIF, GPS, and ICC color profiles in WebP output. Most online converters strip this metadata to save bandwidth, which loses camera info and GPS coordinates. If you need metadata preserved (for archival, professional photography, or geotagged galleries), use a local tool.
Yes — that's exactly the use case EasyImg was designed for. AirDrop or import the photos, drag the folder into EasyImg, pick WebP, click Convert. Even 5,000 photos finish in a few hours. The WebP output is 25–35% smaller than equivalent JPG, which translates directly to faster page loads and less bandwidth on your server or CDN.

Bottom line

HEIC to WebP is the right move when your photos are for the web — blogs, portfolios, product pages, app assets. WebP gives you the same visual quality as JPG at 25–35% smaller files, and every modern browser supports it. For non-web use, HEIC to JPG is the safer pick. EasyImg does both locally so your photos never leave your computer.
