HEIC to ORF Converter
Convert iPhone HEIC and HEIF images to Olympus RAW (ORF) format instantly in your browser - no server upload, no signup required. Batch convert multiple HEIC files at once and download all converted ORF files as a ZIP. Uses the heic2any WebAssembly engine for fast, private, browser-based heic to orf conversion.
Upload HEIC or HEIF files from your iPhone or iPad and convert them to Olympus RAW (ORF) format instantly in your browser. Batch conversion supported - download all as a ZIP. No upload to any server, no signup required.
HEIC files are decoded entirely in your browser using a WebAssembly engine. The first file may take a few seconds while the decoder initialises - subsequent files are faster. ORF output uses Olympus RAW format with TIFF/IFD structure and MakerNote metadata.

Understanding How to Convert HEIC to ORF
What is HEIC to ORF Conversion?
When you convert heic to orf, you transform a compressed HEIC web image into an Olympus RAW Format (ORF) file. ORF is the proprietary camera-raw format used by Olympus (now OM System) digital cameras, built on the standard TIFF container specification with Olympus-specific IFD tags and a MakerNote block. A heic to orf file produced by our heic to orf converter packages the raster pixel data into a standard-conforming ORF TIFF structure that raw-processing software can recognise and ingest.
How Our HEIC to ORF Converter Works
- 1. Upload your file: Drag and drop or browse to select your HEIC or other raster image file. The file is read entirely in your browser - nothing is uploaded to any server when you convert heic to orf online.
- 2. Canvas rasterisation: The image is rendered on an HTML5 Canvas. Transparent regions are blended onto a solid white background (ORF has no native alpha channel). All heic to orf processing is local and private.
- 3. ORF encoding & download: The RGB pixel data is packed into a TIFF-based ORF container with correct IFD entries, BitsPerSample, resolution tags, and an Olympus MakerNote block. Your heic to orf file downloads instantly - or bundled into a ZIP for batch conversions.
Output HEIC to ORF File Structure
- TIFF little-endian header: Begins with
II(0x4949) byte-order mark and TIFF magic number 42, followed by an offset to the first Image File Directory (IFD). - 14 IFD entries: Includes standard TIFF tags for image dimensions, uncompressed RGB encoding, strip offsets, orientation, resolution, and the Olympus MakerNote tag
(0x927c)carrying theOLYMPUS\0IIidentifier. - Uncompressed 24-bit RGB: Pixel data is stored as interleaved RGB bytes (8 bits per sample, 3 samples per pixel, no compression) for maximum compatibility with raw-processing software.
- No alpha channel: The ORF format does not support transparency. Any transparent areas in the source image are pre-composited on white before encoding.
How to Open ORF Files
Olympus RAW files (.orf) can be opened with Adobe Photoshop (via Camera Raw), Adobe Lightroom, Olympus Workspace (the official Olympus desktop RAW developer), and free open-source tools like darktable and RawTherapee. Developers can inspect or convert ORF files programmatically using ExifTool or the libraw C++ library, both of which fully parse the Olympus IFD tags and MakerNote block present in our heic to orf online output.

Frequently Asked Questions About HEIC to ORF Converter
A heic to orf converter is a utility that transforms standard HEIC images into Olympus RAW (ORF) files. When you convert heic to orf, the RGB pixel data is packaged into a TIFF-based ORF container with an Olympus MakerNote tag, complying with the Olympus ORF format specification.
Converting heic to orf image to ORF format is useful for developers testing Olympus RAW image processing libraries, simulating Olympus camera workflows, feeding scientific imaging pipelines, or working with digital asset management systems that expect ORF inputs.
Absolutely! Our heic to orf online converter processes all your files locally inside your browser. No files are uploaded to any servers when you convert heic to orf. Your privacy and data remain 100% on your device.
After you convert heic to orf file, the resulting ORF files can be opened in Adobe Photoshop (via Camera Raw), Adobe Lightroom, Olympus Workspace, darktable, RawTherapee, or using the ExifTool and libraw command-line libraries.
Since our heic to orf converter processes everything locally, limits are based on your device's memory. Most modern browsers can convert heic to orf files up to 50 MB. For larger images, ensure you have sufficient RAM available.
No. The Olympus RAW (ORF) file format does not natively support transparency or alpha channels. When you convert heic to orf files that contain transparent regions, the converter automatically blends the transparent areas against a solid white background.
Yes! Our heic to orf converter supports batch processing. You can upload multiple HEIC files at once. The tool will convert each one to ORF and download them packaged together in a single ZIP archive.
