    Questions

    Does a watermark stop people copying my photos?

    It makes copying less attractive and shows who the picture belongs to. A small mark in a corner can be cropped off; a tiled watermark across the whole picture is much harder to remove, at the cost of covering more of it.

    How do I use my logo?

    Choose “Logo image” and pick the file. A PNG with a transparent background looks best; an SVG works too. The logo is scaled to the size you set, as a share of each photo’s width.

    Will the watermark look the same on photos of different sizes?

    Yes. Size and margin are shares of each picture’s width, so a 5% mark covers the same part of a phone photo and of a small web image.

    Can I watermark iPhone HEIC photos?

    Yes. They are marked at full size and saved as JPG (or the format you choose). The preview shows a sample picture if your browser can’t display HEIC itself.

    How many photos can I do at once?

    Up to 20 files per batch, up to 50 MB each and 200 MB in total. Files are processed one after another; download each one as soon as it is ready, or all of them as a ZIP.

    Very large images are refused to keep your browser from running out of memory: above 100 megapixels on computers and 50 megapixels on phones and tablets. On iPhone and iPad, formats other than HEIC are limited to about 16 megapixels by Safari.

    Is it free? Do I need an account?

    It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
