Reasons to overlay exactly two images
Blending two images is one of the most common editing requests — here's what you can do in minutes.
Double-exposure effect
Blend a portrait and a landscape at 50–70 % opacity for a cinematic double-exposure look.
Add a watermark
Place a transparent logo or signature over any image to protect your work before sharing online.
Merge two photos
Combine two images into a single composite — blend backgrounds, swap skies or layer subjects.
Put a logo on an image
Overlay a brand logo onto a product photo, banner or social post with pixel-precise positioning.
Add a light leak or texture
Overlay a light leak, film grain or bokeh image over a photo for an analogue film feel.
Put a screenshot into a mockup
Place a screenshot or design into a device frame or scene by overlaying the two images.

What you need to blend two images the way you want
Simple enough for a quick merge, precise enough for careful compositing — free either way.
Opacity slider for blending
Drag the opacity from 0 to 100 % to control exactly how the two images mix — from a faint ghost to a solid overlay.
Resize, rotate and flip
Scale the top image to any size, rotate it to any angle, and flip it horizontally or vertically to fit your composition.
Drag freely or snap to position
Drag the overlay anywhere on the canvas, or snap it to a corner, edge or center with a single click.
Crop the base image first
Crop to square, 4:3, 16:9 or freeform before overlaying the second image — useful for social media exports.
Undo if you get it wrong
Step back through your edit history at any point — including crop steps — with a single click.
Download at full resolution
Export the merged result as a lossless PNG at the original image's full resolution. No watermark, always free.
Both images stay on your device — nothing is uploaded
PicOverlay merges your two images entirely in the browser. Neither image is ever sent to a server — all blending happens locally using the Canvas API.

Questions about overlaying two images
How do I overlay two images online for free?＋
Upload your first image as the base, then upload the second image as the overlay. Move, resize, rotate, or fade the second image with opacity control, then export the merged result as a PNG.
How do I control how the two images blend?＋
Use the opacity slider on the overlay layer. At 100 % opacity the top image is fully solid — good for logos and watermarks. Drop it to 50–70 % for a blended or double-exposure look. Experiment until it looks right, then export.
What if my two images are different sizes?＋
The base image sets the canvas size. You can freely resize the top image to fill the canvas, shrink it to a small logo, or anything in between. Proportions are locked by default but can be adjusted.
Can I overlay a PNG with a transparent background?＋
Yes. A transparent PNG composites cleanly — only the visible pixels show, with the base image showing through the transparent areas. This is the best way to add a logo, watermark or cut-out subject.
Can I overlay more than two images?＋
Yes — you can add up to 5 overlay layers on top of your base image. Each layer has its own opacity, position, size, rotation and flip controls.
What format is the exported image?＋
Always a full-resolution, lossless PNG — no compression, no quality loss, no watermark added.
Does it work on mobile?＋
Yes. PicOverlay works in any modern mobile browser — Safari on iOS or Chrome on Android. No app needed.
