HEIC to JPG Converter

Convert iPhone and iPad HEIC photos to lightweight JPG files entirely in your browser using WebAssembly decoders, WebCodecs, and Canvas—no uploads, no compression surprises, perfect for SEO-ready galleries, Shopify product listings, and travel photo backups.

Capabilities

Faster imports with uncompromised fidelity

Instant decoding

Our browser-based HEIC to JPG converter ships HEIC/HEVC decoders compiled to WebAssembly, so iPhone photos become shareable JPGs the moment they land in PolyImg.

Color-accurate output

Maintain EXIF orientation, wide-gamut color profiles, Live Photo depth data, and GPS tags while adjusting compression, resize limits, or metadata stripping.

Local-first workflow

Everything happens client-side with Canvas/WebCodecs, keeping unreleased product shots, medical photos, or ID documents off remote servers.

Skip the cloud handoff—everything compiles down to WebAssembly and runs on local GPU/CPU resources, giving you a true offline HEIC converter.
Workflow

Three steps to HEIC → JPG

  1. 1Drop in HEIC images from your device or use the File System Access picker to grab entire albums of iPhone photos.
  2. 2Choose output quality, resize constraints, and metadata options while referencing live JPG previews and estimated file sizes.
  3. 3Export the finished JPGs in bulk; PolyImg writes them to memory and prompts a single download, naming files exactly how you need.
  • Auto-rotates based on EXIF and keeps capture time/location unless you explicitly remove them.
  • Save and reuse presets (quality, dimensions, metadata) via IndexedDB so consistent exports stay one click away.
Quality & privacy

Studio-grade JPG output with zero trust trade-offs

WebAssembly decoders ensure tone mapping and detail recovery rival native desktop apps—perfect for marketing teams, Shopify sellers, or newsrooms that rely on HEIC captures.

Since the conversion never leaves your browser memory, NDA-protected content, unreleased hardware shots, or event photography stay private end to end.
