Watermark

You can add watermarks to images by overlaying another image on top of your main image.

Note: The maximum accepted image size is 100,000,000 pixels. An image with this many pixels could have width and height combinations like 10,000 x 10,000 or 5,000 x 20,000, etc. There is also a file size restriction. Filestack will not convert an image that is larger than 256mb. Please contact us if you require the ability to process larger files than our current limits.
