Add a watermark to images

What the watermark tool does

Add up to 50 images, then type your text or choose a logo. Pick a position (one of nine spots, from top left to bottom right), a size relative to the image width and an opacity, or repeat the watermark across the whole picture. Every image gets the same watermark at the same relative size, whatever its dimensions. Download them one by one or as a ZIP.

Everything runs in your browser; your images and logo are never uploaded.

Choosing a good watermark

A small, semi-transparent mark in a corner (opacity 30-60%) shows ownership without distracting from the product. A repeated watermark makes copying much harder, which suits photos you share with resellers or post publicly before launch, but it isn't suitable for your own product pages. A PNG logo with a transparent background looks best; white text with the built-in soft shadow stays readable on light and dark photos.

Where to use watermarked images

Watermarks are useful on social media, in catalogues and line sheets, and when sending images to partners. Most marketplaces, including Amazon and Google Shopping, don't allow watermarks or logos on main product images, so keep clean versions for those listings.

Watermark size and placement

Corners are least distracting; bottom right is the most common choice. A size of 3 to 6% of the width keeps a text watermark readable on phones without covering the product. For logos, 10 to 20% usually works. If people crop your watermark out, place it closer to the product or use the repeat option. Test one image first, then process the whole batch with the same settings.

Part of the Product Image Toolkit

This page opens Findora's Product Image Toolkit with this mode selected. The same images can also be resized to Shopify or WooCommerce sizes, converted to JPG, PNG, WebP, PDF or ICO, compressed, cropped, renamed, rotated, watermarked or cleaned of metadata: switch modes at the top and the results update. Each batch takes up to 50 images of up to 40 MB, and every file shows its size before and after, so you always know what you're downloading.
