Do not upscale or enhance
Never upscale a low-resolution image, adding extra pixels only adds to processing time without an increase in accuracy.
It is best to avoid very low-resolution images, if possible.
Keep the aspect ratio
Never change the original aspect ratio. Doing so will create distortions and degrade the performance of the OCR.
