Developer test assets
Download privacy-safe HEIC and HEIF images built from real camera photos. Test file uploads, image decoders, orientation, conversion pipelines, MIME handling, and browser support.
Checking browser support
Testing whether this browser can decode a real HEIC file.
Each file uses an original camera photo that has been re-encoded to remove GPS, capture-time, and device metadata. The resulting fixtures are safe to reuse in public projects, demos, automated tests, and documentation.

Use JPG for a smaller, widely compatible photo. Use PNG when you need lossless output or a PNG-based testing workflow. Both converters process supported files locally on your device.
For developers
The open-source heic-upload-fix package accepts HEIC uploads and converts them into a browser-friendly format before your existing upload flow continues.
npm install heic-upload-fixA browser may allow a user to select a HEIC file without being able to decode or preview it. Support also varies by browser, operating system, and installed codecs. Test file selection, validation, decoding, conversion, and the final rendered output as separate steps.

Read the included licenseHEIF is the broader container format. HEIC commonly refers to a HEIF image encoded with HEVC. Upload systems should usually recognize both the .heic and .heif file extensions and validate the actual file contents rather than trusting either name.
