When to convert ORF to AVIF
ORF is the RAW format from Olympus and OM System cameras that stores raw sensor data. No browser, social network, or web service can display it directly. AVIF is a modern web image format built on a video codec. Its main advantage over JPG and WebP is very high compression efficiency: at comparable visual quality, an AVIF file is noticeably more compact.
AVIF suits websites and web apps where loading speed matters: galleries, portfolios, online shops, news portals. Before switching to it, confirm compatibility: AVIF is supported by modern browsers, but some programs, corporate systems, and older devices cannot open it.
What changes after conversion
AVIF locks the shot into a finished image: brightness, white balance, and color are locked, and the ORF headroom for further correction disappears. Lossy compression produces a very compact file - noticeably smaller than JPG or WebP at close visual quality.
Conversion to AVIF does not improve the original shot: shooting errors remain. AVIF is not intended for printing - photo labs and print shops do not accept it. We recommend keeping the original ORF.
When this is especially useful
- Placing a large gallery on a website with minimal loading time.
- Preparing shots for an online shop where card loading speed matters to customers.
- Creating compact archive copies for browsing without specialized software.
- Publishing a series of frames on a high-traffic news portal.
- Reducing image sizes for a mobile app.

What to check before conversion
- Make sure your target platform and your audience's browsers support AVIF: modern browsers accept it, older ones do not.
- For printing and print production, AVIF is not suitable - choose JPG or TIFF.
- Keep the original ORF files: you cannot recover RAW headroom from AVIF.
- If the file is going to people with unknown device configurations, JPG is safer in terms of compatibility.
Format and conversion limits
AVIF was designed for digital screens and web delivery. Photo labs, print shops, and photobook printing services do not accept it. For printing, convert ORF to JPG or TIFF.
AVIF compatibility is broader than niche formats but narrower than JPG. Some older programs, email clients, and corporate systems cannot open it. For maximum compatibility, choose JPG.
Conversion from ORF does not improve the shot. The result depends on the quality of the source file. If the file is damaged or protected, conversion may fail.
Related tasks
For maximum compatibility - sending by email, uploading to any platform - choose ORF to JPG. For web publishing with slightly wider support than AVIF, ORF to WebP works well. For archiving and printing with maximum data preservation, ORF to TIFF is the right choice.
What is ORF to AVIF conversion used for
Web gallery and photographer portfolio
Photographers convert ORF to AVIF for online galleries. Very compact files ensure fast page loading, which matters for client impressions and search rankings.
Product cards in an online shop
Shop owners photograph products on Olympus or OM System in RAW for maximum detail control, then convert to AVIF. Compact shots speed up card loading.
Content for high-traffic news portals
Editorial teams and photojournalists convert selected ORF frames to AVIF for publishing on high-traffic websites. Smaller file sizes reduce server load.
Compact archive copies for browsing
Photographers with large ORF archives create AVIF versions for convenient browsing without specialized software - at minimal storage space.
Tips for converting ORF to AVIF
Check compatibility before publishing
AVIF is supported by modern browsers but not all programs and devices. On your website, provide a JPG fallback for clients with older software.
For printing, choose a different format
AVIF is not accepted by photo labs or print shops. For printing, convert ORF to JPG or TIFF.
Keep the original ORF files
AVIF is a delivery and display format, not a long-term archive. Keep the original ORF files separately so you can return to the shot and reprocess it if needed.
Allow for longer encoding time
AVIF encodes more slowly than JPG or WebP. When batch-converting a large ORF series, plan time accordingly.
