How to Use the Image Watermarking Tool

1. Upload one or multiple images using drag & drop or the file browser.
2. Choose a Text or Image watermark — or select Both to combine a logo and text in one watermark block.
3. Customize the watermark: opacity, size, rotation, font, color and position (including fully custom X/Y coordinates).
4. Watch the live preview update instantly as you change any setting — click thumbnails to preview each image.
5. Pick an output format (keep original, JPG, PNG or WEBP) and quality.
6. Click Apply Watermark to batch-process every uploaded image with the same settings.
7. Download each watermarked image individually, or grab all of them at once as a ZIP archive.

100% local processing: every watermark is applied inside your browser using the HTML5 Canvas API. Nothing is uploaded, transmitted or stored anywhere — the tool even works offline once loaded.

Originals stay untouched: your source files are only read from disk — never edited, renamed or overwritten. Watermarked copies are brand-new files with generated names like photo-watermarked.jpg.

Frequently Asked Questions

Yes. The tool supports batch processing and applies the same watermark settings to up to 50 images at once, processing them sequentially for reliable performance. You can then download each result individually or all of them together as a ZIP file.

Yes. Choose the Image watermark type and upload your logo — transparent PNG logos work beautifully. You can scale it relative to each image, set opacity, rotate it and place it in any of nine positions or at custom coordinates.

Yes. Select the Text watermark type and customize the text, font family, weight, size and color — plus opacity, rotation and position. Multi-line watermarks are supported too; just press Enter for a new line.

No. Image processing is performed locally in your browser and images are not uploaded to a server by the tool. Your files never leave your device — the tool keeps working even without an internet connection once the page has loaded.

Yes. The opacity control ranges from 0% (invisible) to 100% (fully solid). 40–60% is a popular range for unobtrusive copyright watermarks that still clearly identify the owner.

Yes. The rotation control covers the full −180° to +180° range. Diagonal watermarks around −30° to −45° are a classic choice for photo protection, and the tool automatically accounts for rotation when calculating positions so nothing gets clipped.

Yes. When multiple images are processed, the Download All (ZIP) button bundles every watermarked image into a single ZIP archive, with automatic handling of duplicate filenames so nothing gets overwritten.

The output quality depends on the selected export format and quality setting. PNG preserves lossless image data, while JPG and WEBP use adjustable compression — the quality slider (default 90%) controls that trade-off. Dimensions are never changed: output images keep the exact original resolution.

Privacy notice: your images are processed locally in your browser. The tool does not upload, store, or transmit your images to a server. Files remain under your control and are only used for processing and downloading the generated results.
