One watermark, scaled per image · everything runs on your device

Quick Tool Overview

Bulk Watermark applies one mark to a whole folder and returns a ZIP. The mark is sized as a percentage of each image rather than in fixed pixels, which is what most batch tools get wrong — a fixed watermark is enormous on a thumbnail and invisible on a full-resolution photograph. Filenames survive intact.

About the Bulk Watermark

Watermarking forty photographs individually is the job this exists to remove. Set the mark once, and every file in the queue gets it in the same relative position at the same relative size.

That relative sizing is the part that matters and the part most batch tools get wrong: a fixed pixel watermark is enormous on a thumbnail and invisible on a full-resolution photograph. Here the mark is scaled as a percentage of each image, so a mixed batch comes out looking deliberate. Everything runs locally and comes back as one ZIP with the original filenames intact.

Key features of the Bulk Watermark

Scales per image

The mark is a percentage of each file, so a mixed batch of sizes comes out looking deliberate rather than random.

Set it once

Text or logo, position, opacity and rotation, applied identically to every file in the queue.

Preview every result

Each thumbnail shows the mark in place, so a bad fit is caught before the download rather than after.

One ZIP back

Built in the browser, with original filenames kept, so nothing has to be renamed afterwards.

Safe for unpublished work

Nothing is uploaded, which is the point when the whole reason for the watermark is that the work is not public yet.
