FAQ
Will watermarks be applied to all images?
Yes, the watermark settings will be uniformly applied to all uploaded images. This ensures consistency in batch processing. If different images need different watermarks, it is recommended to process them in separate batches.
What happens if duplicate files are uploaded?
Batch tools automatically deduplicate based on file names. If a file name already exists, it will be skipped and not added again. If you see "All files already exist" when adding more files, it means all file names are duplicates.
How to choose the appropriate watermark position?
Bottom right is the most commonly used watermark position, which does not interfere too much with the main content; center position is suitable for emphasizing overall copyright; bottom left and top right are also common choices. It is recommended to choose the least intrusive position based on image composition.
What opacity level is appropriate?
0.3-0.6 is the commonly used opacity range. Lower opacity (0.3-0.4) makes the watermark more subtle and less distracting; higher opacity (0.5-0.6) makes the watermark more visible, providing better copyright protection.
How to choose font size?
Font size is in pixels. For regular size images (1000-2000 pixels), 16-24 pixels is appropriate; high-resolution images can use larger fonts. It is recommended to preview the effect based on image size before deciding.
Will the output format change?
Batch watermark tool tries to maintain the original format, but only supports keeping JPG, PNG, and WebP formats. If the original image is in another format (such as AVIF, GIF, BMP, etc.), it will be automatically converted to PNG format.
