What does changing the DPI value actually do to my image?

Changing DPI (dots per inch) updates the metadata that tells printers and some software how large to physically print the image — it does not add or remove any pixels from the image itself, so screen appearance is unaffected.

Will adjusting brightness or contrast reduce image quality?

Significant adjustments can reduce fine detail in very bright or very dark areas of the image, similar to how photo editing software works, but moderate adjustments are generally safe.

Can I undo my brightness or contrast changes before downloading?

Yes, you can reset the sliders back to their default position at any point before downloading, since no changes are applied to the original file until you save the result.

Why would I need to change an image's DPI for printing?

Print shops and some document templates specify a minimum DPI (commonly 300 DPI) for photo-quality prints; setting the correct DPI value helps ensure your image is treated correctly by print software.
