Double Exposure Maker
Blend two uploaded photos with real canvas blend modes, adjustable opacity, and repositioning, then export the double-exposure image as a PNG — no upload, all in your browser.
🔒 This tool runs entirely in your browser. Your files are never uploaded to a server.
Two sample gradients are shown by default — upload your own photos to replace them.
How it works
- Upload a base photo and an overlay photo (two sample gradients are shown by default).
- Pick a blend mode — Lighten, Screen, Overlay, Multiply, Difference, or Soft light.
- Adjust opacity and position with the sliders until the blend looks right.
- Click Download PNG to save the composited image.
FAQ
What is a double exposure effect?
It blends two photos into one image, letting the texture or silhouette of one show through the other — a classic darkroom technique now done digitally with blend modes.
Which blend mode should I use?
"Lighten" and "Screen" work well for a portrait silhouette blended with a bright texture like a forest or skyline. "Multiply" darkens instead, and "Difference" gives a more surreal, high-contrast look. Try a few — the preview updates instantly.
Can I reposition the overlay photo?
Yes — use the X and Y offset sliders to shift the overlay photo within the frame without needing an external editor.
What image formats can I upload?
Any format your browser can decode as an <img>, including JPG, PNG, and WebP. Both photos are automatically scaled to fill the canvas.
Are my photos uploaded anywhere?
No. Both images are read locally with the File API and composited on a <canvas> in your browser — nothing is sent to a server, including when you download the result.
