Know the limits
Local does not mean unlimited.
Browser processing protects the file from an upload workflow, but the browser, device, output format, and selected settings still matter.
- Brightening cannot restore detail that was never captured.
- Strong correction can reveal noise, compression artifacts, or color casts.
- Browser re-encoding can change metadata, color behavior, and file size.

Clear answers
Image brightener questions.
Does brightening upload my photo?
No. Pixel adjustment, preview generation, and export happen in this browser without a file-upload request.
Which brightening mode should I use?
Natural is a balanced default, Shadow lift targets darker tones more strongly, and Backlit is intended for subjects photographed against a bright background.
Can this recover an entirely black area?
No. It can reveal dark captured detail, but it cannot reconstruct information that the camera did not record.
