Upload an image, type a caption, and this composites the text onto the bottom of the photo - either on a semi-transparent banner or directly over the image with a drop shadow for legibility - then exports the result as a PNG at the image's original resolution. Composition happens on a canvas entirely in your browser.

When you'd use this

Adding a quick caption or label bar to a screenshot, product photo, or social post image without opening a full image editor.

Labeling a batch of before/after or reference images with a short line of identifying text before sharing or archiving them.

Banner vs. shadow mode

With the background banner switched on, the caption sits on a semi-transparent bar across the bottom of the image - readable over any background. Switching it off removes the bar and instead adds a drop shadow behind the text so it stays legible directly against the photo.

The font size slider sets the size shown in the preview, but the exported PNG scales it proportionally to the image's actual pixel dimensions, so the caption keeps the same relative size at full resolution, not just at preview size.
