About ORF
ORF (Olympus Raw Format) is the proprietary RAW image format used by Olympus cameras and the newer OM System brand. ORF files store unprocessed 12-bit to 14-bit sensor data from Micro Four Thirds sensors, preserving maximum dynamic range and color information. The format includes embedded JPEG previews, comprehensive EXIF metadata, and Olympus's acclaimed in-body image stabilization (IBIS) data.

ORF is the standard RAW format for Olympus/OM System cameras including the OM-1, OM-1 Mark II, OM-5, E-M1X, and PEN series. These cameras are known for exceptional weather sealing and computational photography features like High Res Shot and Live ND. For sharing or web publishing, conversion to JPEG is necessary since RAW formats require specialized software like Adobe Lightroom, Capture One, or OM System's OM Workspace.
PNG (Portable Network Graphics) provides lossless compression with full alpha channel transparency, making it the go-to format for graphics, screenshots, and images requiring pixel-perfect fidelity. Created in 1996 as a patent-free GIF alternative, PNG uses DEFLATE compression and supports both indexed color (PNG-8) and truecolor with alpha (PNG-24/32). Files are 3-10× larger than equivalent JPEGs but preserve every pixel exactly.

PNG is universally supported and ideal for logos, UI elements, diagrams, and any content where transparency or lossless editing matters. For photographic content without transparency needs, JPEG typically offers better compression efficiency.
Frequently Asked Questions
What is an ORF file?
ORF (Olympus Raw Format) is the proprietary RAW image format used by Olympus cameras since the E-1 in 2003, and now by OM System cameras following the 2021 brand transition. ORF files store 12-bit unprocessed sensor data from Micro Four Thirds sensors.
ORF files typically range from 15-25 MB for standard shots, with High Res Shot composites reaching 80+ MB.
Is OM System the same as Olympus?
Yes, they use the same ORF format. In January 2021, OM Digital Solutions acquired Olympus's imaging division and rebranded as OM System. All cameras—whether branded Olympus or OM System—produce identical ORF files.
This converter supports both:
- OM System (2021+): OM-1, OM-1 Mark II, OM-5
- Olympus: E-M1X, E-M1 Mark III/II/I, E-M5 Mark III/II/I, E-M10 IV/III/II/I, PEN-F, E-PL10/9/8/7, E-P7/5
Why choose PNG over JPG for ORF conversion?
PNG provides lossless compression while JPG uses lossy compression. Choose PNG when:
- Archival quality: No compression artifacts, ever
- High Res Shot: Preserve maximum detail from 80MP composites
- Further editing: No quality loss from repeated saves
- 16-bit color: PNG preserves more color depth than 8-bit JPG
Trade-off: PNG files are 2-4x larger than equivalent JPGs.
For smaller files optimized for web sharing, use our ORF to JPG converter.
Is quality preserved when converting ORF to PNG?
Yes, PNG conversion is lossless. The conversion process:
- Demosaics the Micro Four Thirds sensor data via LibRaw
- Applies auto white balance with camera hints
- Converts to sRGB color space
- Compresses with PNG's lossless DEFLATE algorithm
The resulting PNG can be edited repeatedly without quality degradation.
What software can edit ORF files?
ORF files are supported by most professional photo editors:
- OM Workspace (free from OM System) — Native editor with full feature support
- Adobe Lightroom/Camera Raw — Full support via Adobe Camera Raw
- Capture One — Excellent Micro Four Thirds color science
- DxO PhotoLab — Advanced noise reduction for high-ISO ORF
- Darktable (free, open-source) — Full ORF support
Converting to PNG creates a universally compatible format without requiring RAW-capable software.
What are the limits for this converter?
| Tier | Max File Size | Max Files/Batch | Parallel Processing |
|---|---|---|---|
| Guest/Free | 100 MB | 50 files | 3 at once |
| Pro | 1024 MB | 1000 files | 6 at once |
Note: File size limits are specific to this converter. Batch and parallel processing limits apply to all images converters site-wide. See all converter limits →
How are credits calculated for this conversion?
Cost: 1 credit per 5 MB
How it works:
- Files up to 5 MB: 1 credit
- 6-10 MB: 2 credits
- 11-15 MB: 3 credits
- 16-20 MB: 4 credits
Example: A 5 MB photo = 1 credit. A 95 MB photo = 19 credits.
Why per-megabyte? Larger files require more resources (processing, bandwidth, storage).
What are my daily and monthly credit limits?
Credit allocations vary by account tier:
| Tier | Daily Limit | Monthly Limit |
|---|---|---|
| Guest | 100 credits/day | — |
| Free | 100 credits/day | — |
| Pro | — | 12,000 credits/month |
Daily credits (Guest & Free tiers) reset every day at midnight UTC. Monthly credits (Pro) reset on your billing cycle date.
Note: With 1 credit per 5 MB, ORF files under 5 MB cost 1 credit each. Pro users can convert 12,000 ORF files per month.
