How to Watermark Multiple Photos at Once
Watermarking photos one by one is tedious when you have a shoot of 50, 100, or 500 images. Photographers, content creators, and stock image contributors all need a fast way to stamp their brand or copyright notice across a full set of images before sharing or uploading. Batch watermarking tools let you configure the watermark once and apply it to every image in seconds.

Step-by-Step Guide
4 steps · takes under 1 minute
Upload your images
Select multiple JPG or PNG files — there is no hard limit on the number of images. The tool processes them entirely in your browser, so no files are sent to any server.
Set your watermark text
Type your watermark text — typically your name, website, or copyright notice (e.g. © Jane Smith Photography 2025). Keep it concise so it does not dominate the image.
Customise position and opacity
Choose a corner or centre placement. Reduce opacity to 30–50% for a subtle watermark that protects without distracting from the image. Increase to 70–90% if the primary goal is prevention of unauthorised use.
Apply to all images and download as ZIP
Click Watermark All to apply your settings to every uploaded image simultaneously. Download the complete set as a ZIP file ready to share, upload, or send to a client.
