About WatermarkBloom

WatermarkBloom is a free image watermark tool for adding text or logo marks to photos before publishing, sharing proofs, or sending client previews.

Built for local processing

Images are opened by your browser and processed with the Canvas API. There is no account, no upload queue, and no server-side image handling.

What it does

You can upload one or many images, add a text watermark, upload a logo watermark, choose a corner or center position, repeat the mark as a pattern, and export JPG, PNG or WebP files.

For creators, stores and proofs

The tool is designed for common publishing workflows: adding a shop name to product photos, marking client previews as PROOF or SAMPLE, placing a logo on portfolio images, and exporting a consistent batch for blogs or marketplaces.

Presets and templates

Templates provide quick starting points for corner branding, proof images and marketplace photos. Presets are saved only in your browser so you can reuse your own watermark settings later.

What it does not do

WatermarkBloom does not remove watermarks from other people's images. It is intended for attribution, branding and proofing on files you own or have permission to edit.
