Frequently Asked Questions

Will I lose quality converting HEIC to WebP?
Both are lossy formats, so re-encoding introduces a small quality reduction. At default high-quality settings, the difference is visually imperceptible.
Is WebP supported by all browsers?
WebP is supported by Chrome, Firefox, Edge, Safari, and Opera โ€” covering 97%+ of global browser traffic.
Can I open HEIC files on Windows?
Windows 11 natively. Windows 10 requires HEIF Image Extensions. Converting to WebP or JPG avoids this entirely.
What is the difference between HEIC and WebP file size?
Very similar for photographs. Converting HEIC to WebP typically produces a file of similar size or slightly larger (5โ€“15%).
Can I convert multiple HEIC files to WebP at once?
Yes. Batch conversion of up to 10 HEIC files simultaneously.
Does HEIC support transparency?
Yes. Both HEIC and WebP support transparency. It is preserved during conversion.
Is Convertify free to use?
Yes. Completely free, no watermarks, no signup.
Should I convert HEIC to WebP or to JPG?
WebP for web use โ€” 25โ€“30% smaller than JPG. JPG for email, older apps, or platforms without WebP support.

Why convert HEIC to WebP?

HEIC and WebP are both modern formats with excellent compression โ€” but they serve different ecosystems. HEIC is locked to Apple: Safari is the only browser that displays it, and most non-Apple apps cannot open it. WebP is the web standard supported by 97% of global browser traffic.

If you have iPhone photos in HEIC and need them for a website, blog, or web-based platform, WebP is the optimal target โ€” it preserves compression efficiency while adding universal browser compatibility. Converting HEIC to JPG works too, but WebP produces files 25โ€“30% smaller than JPG at equivalent quality.

HEIC vs WebP: compression and quality

Both HEIC and WebP achieve dramatically better compression than JPG. HEIC uses HEVC (H.265), WebP uses VP8 (lossy) or VP8L (lossless). Their compression efficiency is comparable for photographs โ€” both produce files roughly 50% smaller than equivalent JPG.

When converting HEIC to WebP, file sizes typically stay similar or increase slightly (5โ€“15%) because HEVC has a marginal edge over VP8 on photographic content. For maximum compression, consider HEIC to AVIF โ€” AVIF produces files 10โ€“20% smaller than WebP.

WebP browser and platform support in 2026

WebP is supported in all modern browsers: Chrome 23+, Firefox 65+, Edge 18+, Safari 14+, and Opera 12.1+. Global support exceeds 97%. The remaining 3% consists of IE11, Safari 13 and earlier, and some embedded WebViews.

WordPress has supported WebP since version 5.8 (2021). Photoshop added native WebP support in version 23.2 (2022). Most image CDNs serve WebP automatically via content negotiation.

The main gap is email clients โ€” Outlook desktop does not display WebP inline. For email images, convert to JPG instead.

iPhone photos and HEIC โ€” why your files are not JPG

Since iOS 11 (2017), all iPhones default to HEIC for photos. This saves significant on-device storage. When you share via AirDrop, email, or messaging, iOS often auto-converts to JPG for compatibility.

But when you transfer photos via USB, download from iCloud, or use the Files app, you get the original HEIC files. If these need to go on a website, WebP is the best balance of small file size and broad compatibility. You can also change iPhone settings (Settings โ†’ Camera โ†’ Formats โ†’ Most Compatible) to shoot in JPG directly, but this doubles storage usage.

File size after converting HEIC to WebP

A 3 MB HEIC file from an iPhone typically converts to a 3.2โ€“3.5 MB WebP at equivalent quality. Both formats use advanced codecs with comparable compression on photographs.

At lower quality settings suitable for web thumbnails or previews, WebP files can be significantly smaller. Convertify preserves the original quality by default โ€” you get a WebP that looks identical to the HEIC source.

How Convertify converts HEIC to WebP

Convertify uses a Rust backend with libvips for the full pipeline. libheif handles HEIC decoding (including Apple's HEVC variant), and libwebp handles WebP encoding. Color profiles including Display P3 are converted to sRGB for maximum browser compatibility.

EXIF metadata including orientation is preserved. Transparency from HEIC sources is maintained in the WebP output. Files are processed over encrypted HTTPS and deleted immediately after download.
