Add a Watermark to Any Image
Text or logo, corner or tiled, fully transparent or fully opaque. Composited at native resolution in your browser — nothing uploaded, no Pyrelo branding on the output.
Drop the image to watermark
PNG, JPG, WebP
The watermark is composited onto your image entirely in your browser via the Canvas API.
FAQ
Is my image uploaded?▼
No. The watermark is composited onto your image entirely in your browser using the Canvas API. Source image, watermark, and final output never leave your device.
Can I use a logo image as the watermark instead of text?▼
Yes — switch the mode toggle to 'Image watermark' and drop a transparent PNG of your logo. Position, size, and opacity controls work the same way.
What's the 'tile' position?▼
Tile repeats the watermark across the entire image in a grid. Useful when you're publishing photography or branded content and want each region of the image to be visibly attributed — harder to crop out than a single corner mark.
Will it preserve image quality?▼
JPG output uses 92% quality (visually identical to most originals). PNG output is fully lossless. The watermark itself is rendered at the source image's native resolution, so a 4K input produces a 4K watermarked output.
Is there a watermark on the watermark? (Pyrelo branding)▼
No. The output is yours — no Pyrelo logo, no signup, no per-day limit.
Can I rotate the watermark?▼
Diagonal placement is supported in the tile mode (text watermarks are tilted ~30° for the classic 'do not copy' look). Single-position watermarks render straight.
