How ASF Handles PEF Data
Converting from lossless to lossy means some data will be discarded for smaller file size. The quality reduction is carefully controlled. Convert PEF to DNG for wider software compatibility On the output side, Convert ASF to MP4 for cross-platform playback Together, following these practices ensures the best conversion outcome between PEF Raw Photo and ASF Container. Dynamic range — the span from darkest to brightest values — is handled carefully during this conversion. PEF Raw Photo preserves the full range. ASF Container optimizes for typical display capabilities.
Converting a static PEF Raw Photo image to ASF Container video format creates a single-frame video file. This is useful for creating video slideshows, adding images to video editing timelines, or preparing content for platforms that only accept video formats. The output will contain your image as a still frame with the duration and framerate you specify.
Compression trade-off: Your lossless PEF source retains all original data. Converting to lossy ASF will reduce file size substantially, but some data is permanently discarded. Use the quality slider to balance file size against fidelity.

Does this work on my phone or tablet?▼
Yes. Xonvert works on any device with a modern browser — iPhone, iPad, Android phones and tablets all supported.
Can I undo a conversion?▼
Since your original PEF file is never modified, there's nothing to undo. Your source file remains exactly as it was — only a new ASF copy is created.
What if my PEF file won't convert?▼
Ensure the file isn't corrupted or DRM-protected. Try a different file to verify. If issues persist, the file may use an unsupported codec variant.
