Use as little compression as possible when preparing images for watermarking. You don’t need to worry about the file size of the image unless it is over 150MB.
When saving JPG (*.jpg/*.jpeg) images, use one of the following methods of compression:
- Baseline Optimized
When saving TIFF (*.tiff) image, use one of the following methods:
- LZW (recommended)
The ‘None’ compression option for TIFFs is not recommended.
