Convert ORF to PNG — Free Online Converter

PNG is the lossless compressed image format of the web, and converting Olympus ORF RAW files to PNG preserves every pixel of the demosaiced image without any compression artifacts. Olympus OM-D and PEN cameras produce ORF files with 12-bit Micro Four Thirds sensor data that, when rendered to PNG, gives you a clean, artifact-free image suitable for editing, compositing, and any workflow where JPEG compression is unacceptable.

Unlike BMP, PNG uses lossless compression (deflate algorithm) to reduce file sizes by 30-60% without altering any pixel values. This makes PNG the practical choice when you need uncompromised quality from your Olympus RAW conversions in a format that every modern application, browser, and operating system supports natively.

PNG is the standard lossless format for digital workflows. Graphic designers, web developers, and digital artists prefer PNG because it preserves sharp edges, fine text overlays, and subtle color transitions without JPEG's DCT artifacts. If you are compositing Olympus photographs with text, graphics, or transparent layers, PNG as the base image ensures no compression noise interferes with your work.

For web use, PNG excels when image crispness matters more than file size. Product photography shot on Olympus cameras, technical diagrams with photographic elements, and images with text overlays all benefit from PNG's lossless compression. Additionally, PNG supports alpha transparency, which JPEG does not — relevant if you need to cut out subjects from your Olympus photos for compositing.
