How to create smooth QR code with your own custom resolution (size).

The best looking QR code you can get using "Pixel resolution" at the "Customize" tab. However if you need other resolution you can enter it in Save panel. iQR codes offers users to set their custom output resolution of bitmap image file up to 3000px.
To avoid pixels mismatch we strongly recommend to use resolution that can be divided by increment (taken from pixel resolution).

1. Mark down the current resolution.
2. Increase/decrease value in "Pixel resolution" slider under the "Customize" tab.
3. Check the new resolution.
4. If you subtract these resolution you will get an value that is called increment.
5. Use your own custom resolution that can be divided by this increment value.
