Image Overlay & Logo Watermark
Normal mode uses the first image as the canvas and later images as ordered layers. Select a layer thumbnail and set position, scale, angle and opacity in the editing preview. Drag or use arrow keys for placement. Preview and export share the same compositing function. Batch mode uses the last file as a shared logo and every earlier image as a separate background. The same logo settings apply to each result; portions beyond a background are clipped. Use transparent PNG or WebP logos.
Choosing your settings
The first file is the background canvas. Following files are layers in queue order. Set each layer position, scale, angle and opacity. Content outside the background canvas is clipped.
If the result needs another pass
Layers are clipped to the first image canvas. Move the layer inward or reduce its scale; use Image Resizer before composing if necessary.
Good to know
How do I keep a logo background transparent?
Use a transparent PNG or WebP for the logo. JPEG has no alpha channel; export PNG or WebP to retain transparency.
Why is part of my layer missing?
Layers are clipped to the first image canvas. Move the layer inward or reduce its scale; use Image Resizer before composing if necessary.
