Make your mark.

Using Image Watermark

Label a photo or graphic before sharing it, using text or your own PNG logo.

How to use it

1. Choose a source image and select text or PNG logo mode. Enter a single line of text or choose a logo up to 5 MiB.
2. Choose position, opacity, relative size and margin. Text uses the browser sans-serif font; inspect the preview for missing glyphs or low contrast.
3. Create the watermarked image and inspect the output. Adjusting inputs removes the previous download until a new export completes.

Worked example

Input and settings

A 1200 × 800 product photo, a PNG logo, bottom-right placement and 3% margin.

Expected result

A labeled image with the logo near the lower right and the chosen opacity. Actual placement depends on logo proportions.

Limits and common mistakes

• Watermarking does not prevent copying or establish ownership. Use images and logos you are entitled to use.
• Source limit: 25 MiB. PNG logo limit: 5 MiB. Output fits within 2048 × 2048 without enlargement. Large source decoding can still exceed device memory.
• PNG preserves transparency; JPEG flattens it to white. JPEG/WebP output uses quality 90. Animation, metadata and color-profile preservation are not guaranteed.
• Text size is relative to output width and reduced if necessary to fit. Long text and font availability affect its appearance.
