What is this?

A mini design editor that lets you stack multiple image and text layers on a single thumbnail canvas. Drag to position each layer and use sliders for size, rotation and opacity; text layers add stroke, alignment and a background band. Export the result as a single PNG — all in your browser, no upload.

How to use it

Choose a platform → size and a canvas background on the right. Use Add image and Add text to stack layers. Click a layer on the canvas to select it, drag to move, and set size, rotation and opacity with the sliders. Text layers support multi-line input, font, color, stroke, alignment and a background band. Press Export → to save as PNG.

Layer order & management

Reorder with the up/down buttons, toggle visibility with the eye button and remove with the close button in the layer list. Add as many image and text layers as you like.

Note: The selected layer shows a dashed outline (and can be deleted with the Delete key). The outline is not included in the exported PNG.

FAQ

What does this tool do?
It's a mini design editor that lets you stack multiple image and text layers on a single thumbnail canvas. Drag each layer to position it and use sliders for size, rotation and opacity, pick a platform size (YouTube, Instagram, etc.) and export the result as a single PNG — all in your browser.
Can I add a stroke or background band to text?
Yes. Text layers support multi-line input and let you set font, size and color plus a stroke color and width, left/center/right alignment and a readability background band color. Add as many text layers as you like and place each one separately.
Can I overlay several images and texts?
Yes. Add multiple image and text layers, reorder them (z-order), toggle visibility or delete them in the layer list. Each layer has its own position, size, rotation and opacity.
Are my images uploaded to a server?
No. Loading, editing, previewing and saving the PNG all happen in your browser only — nothing is sent to or stored on a server.
