## About HEIC.Best

HEIC.Best (https://heic.best) helps users convert HEIC/HEIF to widely compatible formats and preview HEIC files:

1. **HEIC to JPG/PNG**: Batch conversion with quality control for JPG; PNG supports transparency where applicable.

2. **HEIC to PDF**: Build PDFs with page size, orientation, images per page, and spacing options.

3. **HEIC Viewer**: Preview HEIC in the browser, inspect EXIF metadata, download—without uploading files to a conversion server.

4. **Edge case**: Files named `.heic` but containing QuickTime/MP4-style video containers are detected; the UI suggests downloading with a more accurate extension instead of pretending to decode them as still HEIF.

## Core Features

- **Batch processing**: Multiple HEIC/HEIF files in one session with no fixed file-count limit (practical limit is device/browser performance).
- **Client-side conversion**: Conversion and PDF assembly run in the browser; originals are not sent to HEIC.Best for processing.
- **Privacy**: No registration; see Privacy Policy for cookies, optional error reporting, and data handling.
- **HTTPS**: Site served over TLS.
