Best-in-class encoders

MozJPEG + oxipng + sharp-YUV WebP · production tuned

Convert HEIC to WebP for web publishing — WebPs are typically 30% smaller than the source HEIC and playable in every browser and OS. Best for blog posts, portfolios, and any site where mobile bandwidth matters.

The output uses the same production-grade encoder pipeline as our dedicated Convert to WebP tool: MozJPEG's trellis multipass for JPEG, oxipng at max effort for PNG, sharp-YUV libwebp for WebP, and SSIM-tuned libavif for AVIF. Files are optimized to be measurably smaller than what most online converters produce at the same quality setting.

Why convert HEIC to WebP?

Common reasons to use WebP instead of HEIC: Web publishing, blog posts, portfolio galleries, Core Web Vitals.

How the conversion works

Your HEIC file is decoded in your browser using WebAssembly codecs (no upload, no server processing), then re-encoded as WebP using our production-grade encoder pipeline. The full round-trip typically completes in under a second per file on modern hardware. Nothing about your file is logged, cached, or transmitted anywhere.

Batch, privacy, and downloads

Drop up to 20 HEIC files at once. Each file shows a preview, its before/after size, and a per-file download button. Hit "Download all" to get a single ZIP archive of all converted WebP files. Filenames preserve the original name and swap the extension automatically.

Tool FAQs

Everything you need to know about using HEIC to WebP Converter.

Is this HEIC to WebP converter free?+

Yes — completely free, no signup, no watermarks, no upload limits beyond the client-side batch cap of 20 files and 20 MB per file. Because everything runs in your browser using WebAssembly, there's no server cost for us to pass on.

Are my HEIC files uploaded anywhere?+

No. The tool loads WebAssembly codecs directly into your browser and processes every file locally. Open your browser's Network tab while you drop a file — you'll see zero requests fire. That makes it safe for private photos, unreleased designs, medical images, or any file you'd rather not share.

How is the WebP quality?+

The tool uses the same production-grade encoder as our dedicated Convert to WebP converter — MozJPEG for JPEG, oxipng for PNG, sharp-YUV libwebp for WebP, SSIM-tuned libavif for AVIF. At the default Balanced preset, output is visually indistinguishable from the source at normal viewing distances.

Can I batch-convert HEIC to WebP?+

Yes — drop up to 20 files at once. Each file is processed serially in your browser (WebAssembly memory stays bounded) with a per-file progress bar. When done, download files individually or grab a single ZIP of everything.
