FAQ
- Are my images uploaded to convert them?
- No. The scan is decoded and rendered locally in your browser (WebAssembly + WebGL); the exported JPG/PNG is generated on your device and never leaves it.
- JPG or PNG — which should I choose?
- PNG is lossless and best for sharing with a doctor; JPG is smaller for email or messaging. Both export the exact slice you are viewing.
- Does the image contain patient identity?
- The exported image is just the pixels of the slice — DICOM identity tags are not rendered or embedded. Always double-check before sharing.
