    Frequently asked questions

    How many photos can I batch watermark at once?

    There is no fixed limit in the tool — the practical ceiling is your device's memory, since every photo is processed in the browser. Laptops handle larger batches than phones; if a very large batch slows down, split it into a few smaller ones.

    Are my photos uploaded?

    No. Every image in the batch is processed inside your browser using Canvas. Nothing is sent to a server, which is what makes batch watermarking safe for a full shoot of client-facing photos or a stack of ID copies.

    Do I get one ZIP file or individual downloads?

    One ZIP containing every watermarked photo, built in the browser so nothing hits the network. To save a single photo on its own, use the main watermark page instead.

    Can I use different watermark text on different photos?

    The current batch mode applies one shared watermark to all photos in the batch, which is what most photography and real-estate workflows need. For per-image customisation, process photos one at a time on the main watermark page.

    What formats does batch support?

    JPG and PNG. Mixed batches work, and each exported photo keeps its original format. Convert WebP or HEIC photos to JPG first with the image converter.

    How long does 100 photos take?

    It depends on your device and the photos' resolution. Because everything runs locally, there is no upload or server queue — larger batches simply take proportionally longer.
