What the tool does
The tool adds watermarks to images without uploading files to a server. It supports text watermarks, logo watermarks, position, opacity, size, margin, rotation, quality, and export to JPG, PNG, or WebP.
How to use it
- Add one or more images.
- Choose text or upload a logo, then set position and opacity.
- Download all finished images as one ZIP archive.
Text watermark or logo
A watermark helps mark ownership, brand, draft status, or image source before publishing. Text mode works for a brand name, website, order number, or draft label, while logo mode is better for ready-made PNG/SVG branding, studio photos, and client materials.
Position, size, opacity, margin, and rotation let the mark be obvious or almost invisible. Use tiled placement when you need to protect previews from easy copying. For polished website or social media publishing, a corner logo with moderate opacity is often enough.
Batch preparation for sites and sales
Add many images, configure the watermark once, and download the result as a ZIP archive. This is useful for product photos, portfolios, real estate sets, menus, training materials, marketplace previews, and content that needs approval.
Before processing a large batch, check the first image in the preview: the watermark should not cover an important product, face, text, or button in a mockup. For mixed aspect ratios, choose center, corner, or tiled placement based on where the main subject sits.
Formats, quality, and privacy
Export is available as JPG, PNG, and WebP, with original format where possible. JPG creates lightweight photos without transparency, PNG is better for graphics and transparent logos, and WebP often reduces website asset size. Quality affects JPG and WebP: lower values create smaller files but can add artifacts.
All images and the logo are processed locally in the browser, without uploading to the All Tools server. Practical limits depend on file size, device memory, and which input formats your browser can read. Some HEIC/AVIF files may not open in every browser.
