## FAQ

### Does changing DPI change the image dimensions?

By default, only the DPI metadata is changed. You can optionally resample the image to change actual pixel dimensions.

### What DPI should I use for printing?

300 DPI is standard for high-quality prints. 150 DPI works for large posters. 72 DPI is standard for web display.

### Does this preserve EXIF metadata?

EXIF survives. DPI changes only update the resolution tags — the pixel data and the rest of the metadata block come through unchanged.
