Quality reduction ahead
ORF is lossless, meaning every bit of data is preserved. HEIF uses lossy compression — some data is permanently discarded to reduce file size. At high quality settings the difference is usually imperceptible, but the original data cannot be recovered.
Some metadata may not survive
Your ORF file may contain MakerNote metadata. HEIF has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Color depth reduction: 12-bit → 10-bit
ORF stores up to 12 bits per channel, but HEIF supports only 10 bits. You may notice banding in smooth gradients (like sky or skin tones) where subtle color transitions are lost.
What compression artifacts to expect
HEIF lossy compression can produce blurring and occasional color shifts. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.

About ORF (OLYMPUS) to HEIF Conversion
ORF (introduced 2004) and HEIF (introduced 2015) are both image formats, but they differ in important ways. ORF is Olympus's RAW photo format with full sensor data. HEIF stores images using highly efficient HEVC compression, commonly used on Apple devices.
Full Name: ORF uses Olympus RAW, while HEIF uses High Efficiency Image Format. Compression: ORF uses Lossless, while HEIF uses Lossy. Transparency: ORF uses No, while HEIF uses No.
When you convert ORF to HEIF, the goal is to reduce file size without visible quality loss. HEIF lossy compression can produce blurring and occasional color shifts. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes. Understanding these technical differences helps you choose the right format for your workflow.
Your ORF file is decoded and re-encoded as HEIF. The conversion involves 4 steps: (1) your orf file is uploaded and the format is validated, (2) the file content is decoded into its raw representation, (3) the data is re-encoded in heif format with optimal settings, (4) the converted file is ready for download.
CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.
This conversion is ideal when you Your ORF file is too large for email attachments or upload limits, or when you You want to reduce storage usage without noticeably affecting quality. For the opposite direction, CocoConvert also supports HEIF to ORF conversion.
How to Convert ORF (OLYMPUS) to HEIF
- 1
Upload .orf file
Select your ORF file by dragging it to the upload zone or using the file picker. Batch upload is available for multiple files.
- 2
Choose .heif
Set HEIF as the output format. The converter uses optimal settings based on the ORF→HEIF conversion profile.
- 3
Convert
The server-side engine decodes your ORF file and re-encodes it as HEIF. Processing time depends on file size and complexity.
- 4
Download result
Grab your converted .heif file. Multiple output files can be downloaded together.
What Happens When You Convert ORF (OLYMPUS) to HEIF
Your ORF image is decoded into raw pixel data, then re-encoded as HEIF. Some quality is permanently lost during compression. CocoConvert uses high-quality defaults to minimize this.
Your ORF file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
Pixels are re-encoded using High Efficiency Image Format's lossy compression algorithm
Metadata (EXIF, ICC profiles) is transferred where HEIF supports it
The HEIF file is saved and ready for download

Frequently Asked Questions
What is the difference between ORF and HEIF?
ORF is Olympus's RAW photo format with full sensor data. HEIF stores images using highly efficient HEVC compression, commonly used on Apple devices. Full Name: ORF uses Olympus RAW, while HEIF uses High Efficiency Image Format. Compression: ORF uses Lossless, while HEIF uses Lossy. Transparency: ORF uses No, while HEIF uses No.
Does ORF to HEIF conversion affect quality?
HEIF lossy compression can produce blurring and occasional color shifts. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
Which format has better compression, ORF or HEIF?
ORF uses lossless compression. HEIF uses lossy compression. The better choice depends on whether you prioritize file size or quality.
How long does ORF to HEIF conversion take?
Most conversions finish in seconds. Larger files or complex image content may take 10–30 seconds. CocoConvert processes files in parallel for batch jobs.
Is ORF or HEIF better for long-term storage?
ORF is better for archival since it's lossless.
