Overlay Merge (Layers)
- ✅ Blend Modes: multiply / screen / overlay
- ✅ Layer Mask (brush/gradient) + smart crop
- ✅ Template pack: double exposure, poster overlays, etc.
- ✅ 8K / unlimited layers + batch export + AVIF/TIFF/PSD
❓ Overlay Merge Tool FAQ
This tool overlays images as layers to create a single composite. Processing stays in your browser (no upload). Download as JPG/PNG/WebP/BMP.
What is overlay merge used for?
Logo overlay, watermark-like placement, frames, textures, and combining two images into one scene are common use cases.
Do transparent PNG layers work?
Yes. PNG/WebP transparency works well. JPG/BMP do not support transparency, so those layers behave as solid images.
Why does layer order matter?
Top layers cover bottom layers. Logos/frames should be on top; backgrounds should stay below.
What does opacity change?
It controls how transparent the top layer is. Low opacity is great for textures; medium opacity works well for watermarks.
How should I align layers?
Use center/corner alignment or x/y controls if available. A practical method is: center first, then small nudges to perfect placement.
Why do I see overflow at the edges?
If a layer is larger than the canvas, overflow is expected. Use scaling/fit controls (if available) to contain it.
Preview vs Export—what’s the difference?
Preview is optimized for speed while editing. Export generates the final file at full quality.
Which format is best?
Need transparency: PNG/WebP. Photo-heavy: WebP/JPG smaller. BMP is for special needs and uses a dedicated encoder.
What does PRO add?
PRO can unlock advanced blend modes, masking/selective overlays, faster processing at high resolution, and batch export pipelines.
Tip: Opacity and alignment are the two key settings for natural-looking overlays.
