Place a logo, watermark, sticker or texture on top of a photo. Drag it into position, resize from the corners, set opacity and a blend mode, then download one flat image.
Composites a second image over a background image at the position, size, rotation and opacity you choose, using the same blend modes you would find in an image editor. The overlay keeps its transparency, so a PNG logo with a see-through background sits cleanly on the photo. You drag it around on the preview or type exact pixel offsets; the corner handles scale it uniformly, and the whole picture is rendered at the background’s full resolution when you download.
A 3000 × 2000 product photo needs a shop logo in the bottom-right corner. Drop the photo, add a 800 × 300 transparent PNG logo, click Bottom right, set Size to 60 % (480 × 180 px) and Opacity 85 %. Download as JPEG at quality 92 and the file is about 1.1 MB. For a paper texture over a portrait, add a 2000 × 2000 JPEG texture, click Fit whole so it covers the frame, choose Multiply and drop Opacity to 40 %.
Use it for watermarks, logos on product shots, stickers and badges, textures, light leaks and one-off composites where one picture sits on another. If you only need words, Add Text is quicker. To put two pictures next to each other rather than on top, use Merge Images. If your overlay still has a white box around it, run it through Remove Background first so only the subject is placed.
Size is a percentage of the overlay’s own pixels, so 100 % keeps it as is and Fit whole scales it to cover the background. Opacity fades it; 30 to 50 % is typical for a watermark. Blend changes how the colours combine: Multiply makes white parts vanish and is right for a dark logo on a light photo, Screen makes black parts vanish for a light logo on a dark photo, Overlay and Soft light add texture without hiding the picture. Rotate and the two flip switches turn the overlay without changing the background.
Why does my logo have a white box around it? The logo file is a JPEG or a PNG without transparency. Use Remove Background on it first, or choose the Multiply blend, which makes white disappear.
Can I add more than one overlay? One at a time: download the result, drop it back in as the new background and add the next overlay. Settings are remembered between rounds.
Where is the position measured from? From the top-left corner of the background to the top-left corner of the unrotated overlay, in background pixels. Negative numbers let it hang off the edge.
Does anything leave my computer? No. Both pictures are combined inside your browser and the page keeps working offline.
