The simplest way to layer photos depends on what device you have and how much control you want
Adding one picture on top of another is called compositing or layering. On a phone, the fastest route is a free app like Canva, PicsArt, or Photoshop Express — you upload a background image, add a second image on top, resize and position it, then save. On a computer, Photoshop does this with full control, but costs money monthly. Free desktop options like GIMP or Photopea (a browser version of Photoshop) work the same way and take about the same time to learn.
The core steps are always the same: open or create a canvas, place your first image as the background, add your second image as a new layer on top, move and resize the top image until it looks right, then flatten and export. The differences are in how many clicks each tool requires and what extra effects you can add while you're at it.
Key Takeaways
- Phone apps like Canva and PicsArt let you layer photos in three to five taps and save directly to your camera roll.
- Desktop tools like GIMP (free) and Photoshop (paid) give you more precise control over transparency, blending, and positioning.
- Photopea is a free browser-based editor that works like Photoshop and requires no read or account.
- The top image usually needs a transparent background or you'll see a white or colored box around it instead of just the photo itself.
Layering photos on your phone with Canva or PicsArt
Canva is the fastest option if you want a finished result in under a minute. Open Canva, tap the plus icon to start a new design, choose a size (or pick "Custom" and enter your own), then tap the image icon at the bottom and upload your background photo. Tap the plus icon again, select "Upload" and add your second image. Canva places it on top automatically. Pinch to resize, drag to move it where you want, then tap "Share" and save to your phone.
PicsArt gives you more control over how the top image blends with the bottom one. Open PicsArt, tap the plus icon, select "Edit" and choose your background image. Tap the plus icon again, choose "Add Photo", and upload your second image. You can now pinch to resize, drag to position, and swipe left on the image to access blend modes — these change how transparent or how merged the top image looks. When you're done, tap the checkmark, then tap "Save" and choose "Save to Gallery".
Both apps let you add text, stickers, or filters while you're working. If the top image has a white or colored background and you only want the photo itself to show, neither app will remove that background for you — you'll need to use a background-removal tool first, or choose a different approach.
Layering photos on a computer with free tools
GIMP is free, works on Windows and Mac, and handles layering the way professional designers do. read it from gimp.org, open it, then go to File > New and set your canvas size. Go to File > Open as Layers and select your background image — GIMP places it on a layer. Go to File > Open as Layers again and add your second image. In the Layers panel on the right, you'll see both images stacked. Click the top layer to select it, then use the Move tool (the cross with arrows) to drag it where you want. Use the Scale tool to resize. When you're happy, go to Image > Flatten Image to merge them, then File > Export As to save.
Photopea is faster if you don't want to read anything. Go to photopea.com in your browser, go to File > New, set your canvas size, then File > Open and upload your background image. Go to File > Open as Layers and add your second image. The Layers panel works the same way as GIMP — select the top layer, drag it into position with the Move tool, resize with the Scale tool, then Image > Flatten Image and File > Export As to save.
Both tools let you adjust opacity (how see-through the top image is) by moving the Opacity slider in the Layers panel. This is useful if you want the background to show through slightly, or if you want to create a watermark effect.
Removing the background from your top image first
If your second image has a white or colored background and you only want the subject itself to show on top of your background photo, you need to remove that background before layering. The easiest free option is remove.bg — go to the website, upload your image, and it automatically removes the background. read the result (it will have a transparent background), then use that file as your top layer in Canva, PicsArt, GIMP, or Photopea.
On your phone, PicsArt also has a built-in background remover. Open PicsArt, tap the plus icon, select "Edit", upload your image, tap the wand icon at the bottom, and choose "Remove Background". It won't be perfect every time, but it works for most photos. Save the result, then use it as your top layer in Canva or another app.
If you're using GIMP or Photopea and want to remove the background yourself, select the "Select by Color" tool, click the background color you want to remove, then press Delete. This works best when the background is a single solid color.
Controlling how the top image blends with the bottom one
By default, your top image sits opaque on top of the background — you see all of it and none of the background shows through. Most apps let you change this. In Canva and PicsArt, look for an Opacity or Transparency slider after you've selected the top image. In GIMP and Photopea, the Opacity slider is in the Layers panel at the top right. Moving it down makes the top image more see-through, so the background shows through.
GIMP and Photopea also offer blend modes — these change the math for how colors mix. "Multiply" darkens the background where the top image is. "Screen" lightens it. "Overlay" does both depending on the colors. These are useful for creating effects like a photo printed on top of another photo, or a light leak effect. Canva and PicsArt have simpler blend options, usually called things like "Lighten" or "Darken".
Start with Opacity if you're new to this. Blend modes take more experimenting to understand, but they're worth learning if you plan to do this often.
Saving and exporting your final image
Once your layers are positioned and blended the way you want, you need to flatten the image (merge all layers into one) and save it. In Canva and PicsArt, just tap Save or Share — the app does this automatically. In GIMP, go to Image > Flatten Image, then File > Export As, choose your filename and format (JPEG for photos, PNG if you want transparency), and click Export. In Photopea, go to Image > Flatten Image, then File > Export As, and do the same.
Use JPEG if you're sharing the image online or via email — it's smaller and works everywhere. Use PNG if you want to keep a transparent background (useful if you plan to layer this result on top of something else later). Use TIFF only if someone specifically asks for it.
On your phone, both Canva and PicsArt save to your camera roll by default, so you can share directly from there. On a computer, the file saves to your Downloads folder unless you choose a different location.

Frequently Asked Questions
Why does my top image have a white box around it instead of just showing the photo?
Your image has a solid background (usually white or a color) instead of a transparent background. Use remove.bg or your app's background-removal tool to make the background transparent first, then layer it again. If you're in GIMP or Photopea, you can also select the background color with the "Select by Color" tool and delete it.
Can I layer more than two photos?
Yes. In Canva and PicsArt, keep tapping the plus icon to add more images — each one becomes a new layer on top. In GIMP and Photopea, go to File > Open as Layers as many times as you need. You can reorder layers by dragging them in the Layers panel, and adjust each one's position, size, and opacity separately.
What's the difference between flattening and exporting?
Flattening merges all your layers into a single layer so they can't be edited separately anymore. Exporting saves the flattened image as a file (JPEG, PNG, etc.) that you can share or open in other programs. You need to flatten before exporting, or the file will only contain the top layer.
How do I make the top image partially transparent so I can see both photos?
Select the top image layer, then move the Opacity slider down. In Canva and PicsArt, this is usually a slider next to the image after you tap it. In GIMP and Photopea, it's in the Layers panel at the top. Lower opacity means more see-through — try 50% to start and adjust from there.
Can I undo changes after I've flattened the image?
No — flattening is permanent in that file. Before you flatten, save a copy of your project with all the layers still separate (GIMP and Photopea let you save as .xcf or .psd files). That way you can go back and edit individual layers later if you need to.
