Frequently asked questions

Are my files uploaded to a server?: No. All image processing runs entirely in your browser on your device. Your files are never uploaded, stored, or transmitted to any server.
Will adjusting brightness reduce image quality?: Moderate adjustments are safe. Extreme pushes can introduce banding or noise, especially in JPEG files that were heavily compressed originally.
What is the difference between brightness and exposure?: Brightness shifts all tones uniformly. Exposure adjustments often mimic camera exposure, affecting highlights and shadows differently for a more natural result.
Can I undo adjustments after downloading?: Downloaded files are flattened. Keep your original file if you may need to re-edit from scratch later.
Should I adjust before or after cropping?: Either order works. Many editors crop first to focus adjustments on the final composition.
How do I fix an overexposed photo?: Lower brightness and exposure slightly, then add contrast to restore definition. Severely clipped highlights cannot be fully recovered.
Does adjusting colors help with printing?: On-screen edits may look different in print. Calibrate saturation conservatively and request a proof for critical jobs.
