How to use this tool

1. Open the Uvolix Add Image Watermark.
2. Select the supported image or PDF file from your device.
3. Adjust the available output settings and preview the result.
4. Process the file, verify the output and use the download or copy button.

Quality and compatibility

For important work, compare the output with the original at full size. JPG is suitable for photographs, PNG is useful for lossless graphics and transparency, and WebP often provides smaller web images.

Privacy

Processing happens locally in your browser. Uvolix does not upload or store the selected file. Avoid sharing generated Base64 data when the source image is private.

Keep the original

Conversions, compression, cropping and metadata removal can permanently discard information. Keep an unchanged original until you verify the downloaded result.
