Practical example and settings

Example: To mark a listing photo, enter your name or website, turn off repetition and choose a corner. For a proof image, repeat the text across the photo and adjust opacity until the subject remains visible.

Choose your settings: Choose a font, text size and colour that remain readable over the photo. Tiled watermarks also have an angle control. Text and placement update in the preview and are included in the download.

If the result is unexpected: If the mark is hard to see, increase opacity or contrast and try the dark outline. Inspect the exported image at its intended display size. A watermark discourages casual reuse but cannot guarantee copyright protection or prevent removal.

Questions about this tool

Do I need to click Apply to see it?

No. Text, style and intensity update the preview immediately. The editable watermark is included once in each download.

Can I cover the whole image with repeated text?

Yes. Enable Repeat across the image and adjust the repeat angle and opacity. Bold, italic and outline controls are available.

How privacy works

Good to know

File limits, export quality and local processing.

Is my image uploaded?

No. The editor reads the image you select and processes it locally in your browser. We do not receive or store your image.

Which files can I use?

Static JPG, PNG and WebP images up to 15 MB and 16 megapixels, with no side longer than 8,192 pixels. GIF, HEIC, SVG, RAW and animated images are not supported.

Will a smaller file have the same quality?

JPG and WebP compression can remove detail. Compare the prepared result before downloading. PNG export is lossless for the edited pixels, but the file can be larger than the original.

Can PicMender find faces automatically?

Yes. Use Find faces automatically to suggest areas, then check and adjust them. Detection can miss faces or select the wrong area. Manual rectangles and circles remain available, and edits are included in the downloaded image.

Does it preserve camera metadata?

The editor creates a new image from pixels; original camera metadata, colour profiles and print resolution are not retained as an editing feature. Colours and fine detail may differ from the original.
