Frequently Asked Questions

Everything about the free Watermark Adder by Tradesala.

Yes — 100% free, no signup, no subscription. The tool runs entirely in your browser. Your images are never uploaded to any server.

No. All image processing happens locally in your browser using the Canvas API. Your images never leave your device. This makes the tool both safe and fast.

You can bulk watermark up to 100 images at once. All images receive the same watermark settings you configure in the settings panel. Download them as individual files or as a single ZIP archive.

Two types: Text watermark — type your brand name, choose font, size, colour, style and opacity. Logo watermark — upload a PNG logo, set size and opacity. Both support 9-point grid positioning, free drag-and-drop placement, rotation and tiling.

Input: JPG, JPEG, PNG and WebP. Output: PNG (lossless, best for transparent backgrounds) or JPG (smaller file size, best for product photos on marketplaces).

Watermarking protects your product photos from being copied and used by other sellers without permission. It also reinforces brand identity — buyers who see your watermarked images on social media or search results know who the original seller is. On Tradesala, Amazon, Flipkart and Meesho, a branded watermark builds trust with potential customers.

Important: Place the watermark in a corner or edge — never over the main product. A watermark that covers the product obstructs the buyer's view, reduces conversion, and may get your listing flagged on some platforms. Use a low-to-medium opacity (30–60%) so the watermark is visible but the product remains the focus.
