Some formats cannot save information on DPI parameters.
Some graphics formats, e.g. GIF, do not support DPI parameters.
If the format supports DPI settings, you can alter DPI dimensions before converting images.
The default conversion algorithm is as follows:
- With formats which do not contain information on DPI, the size will be set to 72×72 DPI.
- With formats which contain information on DPI, the current DPI size will be preserved.
- Find Resize operation.
- Enter new DPI size into "new DPI" textbox.
