For Photos:
- • Loss of fine details

- • Reduced editing flexibility
- • Lower print quality
For Videos:
- • Blocky artifacts
- • Reduced sharpness
- • Color degradation

Frequently Asked Questions
Does OfflineSharing compress files?
No, OfflineSharing transfers files in their original quality with no compression or quality loss. Files are transferred byte-for-byte exactly as they exist on the source device.
How can I verify no quality was lost?
Check the file properties after transfer - the file size should be identical to the original. For photos, you can also examine EXIF data and pixel dimensions to confirm they match.
Do larger files transfer more slowly?
While larger files do take more time to transfer, OfflineSharing's direct device-to-device connection offers much faster speeds than internet-based transfers, making it practical even for large RAW photos and 4K videos.
