Our Story & Mission

Rethinking Image Conversion for the Modern Web

DropHEIC was built with a single, clear objective: to provide a lightning-fast, 100% private, and completely free HEIC image converter that operates directly inside your web browser without sending a single byte of photo data to cloud servers.

Why We Built DropHEIC

100% Client-Side Privacy

Your personal photos contain private memories, location metadata, and sensitive visual details. Traditional online converters force you to upload your images to third-party servers. DropHEIC processes everything locally on your device hardware using WebAssembly.

Instant Browser Speed

Uploading multi-megabyte iPhone photo libraries over slow internet connections wastes valuable time and bandwidth. By converting images directly inside browser memory, DropHEIC processes files instantly at native device speeds.

Zero Paywalls or File Limits

No subscriptions, no registration forms, no daily upload caps, and no watermark traps. We believe fundamental utility tools should be free, accessible, and transparent for everyone on Mac, Windows, iOS, and Android.

TECHNICAL ARCHITECTURE

Powered by Modern WebAssembly

When Apple adopted HEIC (High Efficiency Image Container) in iOS 11, millions of Windows PC and web application users lost the ability to open iPhone photos natively.

DropHEIC solves this ecosystem divide by leveraging web-standard WebAssembly (WASM) modules compiled from C/C++ image decoders. When you drop a .heic or .heif photo into our app, your browser compiles and executes high-speed decoding instructions directly on your system CPU.

Native Code Execution: Decodes HEVC-compressed image streams at near-native C++ performance inside your browser engine.
Multi-Format Output: Converts decoded image canvas buffers into JPEG, PNG, WebP, or multi-page PDF documents.
Batch ZIP Packing: Compresses converted batch files into neat .zip downloads locally using client-side JSZip algorithms.
