Why convert HEIC to WebP?
HEIC is efficient on your iPhone, but it’s a dead end on the web. Most websites, content platforms, and browsers won’t display or accept a raw HEIC file.
Converting HEIC to WebP turns that iPhone photo into a modern, lightweight image built for the web — one that loads fast and uploads anywhere.
Converting HEIC to WebP gives you a smaller, web-ready image that loads faster and uploads to any modern website or CMS.
Smaller files, faster pages
WebP is roughly 25–35% smaller than an equivalent JPEG or PNG. Lighter images mean faster page loads and better performance scores.
Works in every modern browser
WebP is supported by Chrome, Firefox, Edge, Opera, and Safari 14 and later. A HEIC to WebP conversion produces an image every modern browser can render.
Upload to any CMS
WordPress, Shopify, Squarespace, and most platforms accept WebP but reject HEIC. Converting first lets you publish iPhone photos without upload errors.
What is a HEIC file?
HEIC stands for High Efficiency Image Container, the format Apple uses to store photos on iPhones and iPads.
A HEIC file is Apple’s high-efficiency photo format, used on iPhones since iOS 11.
Why does my iPhone save photos as HEIC?
Since iOS 11, Apple has used HEIC by default because it stores photos at about half the size of JPEG. It’s efficient on the device, but poorly supported outside Apple’s ecosystem — especially on the web.
HEIC vs HEIF
HEIF is the underlying standard; HEIC is Apple’s implementation of it. The .heic files from your iPhone are what you’ll be converting.
What is WebP?
WebP is a modern image format created by Google specifically to make images on the web smaller and faster.
WebP is a modern image format from Google that makes web images significantly smaller while supporting transparency.
A modern image format by Google
WebP was designed for the web from the start, which is why it compresses so well and is now supported across all major browsers.
Lossy, lossless, and transparency
WebP supports lossy compression (like JPG), lossless compression (like PNG), and an alpha channel for transparency. Our converter produces high-quality lossy WebP that’s optimized for the web, with an adjustable quality slider.
HEIC vs WebP: key differences
Here’s how the two formats compare.
| HEIC | WebP | |
|---|---|---|
| File size | Smallest | Small (great for web) |
| Web support | Very limited | Every modern browser |
| CMS uploads | Usually rejected | Accepted |
| Transparency | Not supported | Supported (alpha) |
| Best for | Storing photos on a phone | Images on websites |
File size
Both formats are efficient. WebP is purpose-built for the web and is far smaller than the JPEG or PNG you’d otherwise use online.
Quality
WebP quality is adjustable. You choose how much compression to apply when you convert HEIC to WebP.
Browser & web support
This is the decisive difference. HEIC barely works on the web, while WebP is a first-class web citizen.
Transparency
Both formats differ here too: WebP keeps an alpha channel, so transparency survives the conversion.
WebP for web performance
If you care about how fast your site loads, WebP is one of the easiest wins available.
Better Core Web Vitals
Smaller images improve your Largest Contentful Paint (LCP) and overall page speed. Converting HEIC to WebP is a quick way to shrink your image payload.
CMS & platform compatibility
Because platforms accept WebP directly, you skip the “unsupported file type” errors that HEIC triggers. Upload, publish, done.
Does WebP keep transparency?
Yes — and this is where WebP beats JPG.
Yes, the alpha channel is preserved
If your source image has transparent areas, a HEIC to WebP conversion keeps them intact. JPG would fill those areas with white; WebP does not.
Choosing the right WebP quality
You control the trade-off between sharpness and file size.
A good default for the web
A quality of around 80 is an excellent web default — visually crisp but much lighter. Raise it for maximum detail, or lower it for the smallest possible files.
Is it safe to convert HEIC to WebP online?
Many converters upload your photos to a server first. HEICHub does not.
Because the conversion runs in your browser, your HEIC files are never uploaded — they stay on your device.
Your files never leave your device
The entire HEIC to WebP conversion happens locally, so your photos stay private. It’s also fast, because there’s no upload to wait for.
