Frequently Asked Questions
What's the maximum number of files I can convert at once?▼
Free users can convert several files per batch. PRO users enjoy unlimited batch sizes. For very large batches, your device's memory is the only practical limit.
Why choose EXR over other formats?▼
OpenEXR Image offers 32-bit float HDR with multiple channels for compositing. It's widely used for VFX compositing, HDR photography and 3D rendering output, making it an excellent choice for most image needs.
Will my PNM file be deleted after conversion?▼
No. Your original PNM file is never modified or deleted. Xonvert creates a separate EXR copy — your source file remains untouched.
What image quality settings should I use?▼
For photos, use the High quality preset. For web graphics, Medium offers a good size-quality balance. The default preset works well for most use cases.
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 PNM file is never modified, there's nothing to undo. Your source file remains exactly as it was — only a new EXR copy is created.
What if my PNM 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.
