Sometimes the picture you need does not exist as a single photo. The free AI image combiner on CanvaPro fuses two or three stills, guided by a prompt, into one composition. You do not need an account, and the usual download does not pick up a watermark from the page.
The live form asks for two or three images in the same box. Each file can be JPEG, JPG, PNG, or WEBP up to 20 MB. A prompt is required — write what each picture should contribute. Complete the security check and click Combine Images. The job is queued as a multi-fusion request, and the combined still appears in the output panel when it is ready.
This is not a collage grid
A simple collage places photos side by side. This tool tries to blend people, products, outfits, or backgrounds into one scene. The prompt is the instruction for that blend. “Put the bicycle from image 1 on the lavender path from image 2, morning light” is more useful than “merge these nicely.” If a third image holds a person or a prop, say so clearly.
You must upload at least two files and no more than three. A single photo will not start, and a fourth will not be added. Use pictures you have the right to edit, and get consent if a face belongs to someone else.
When you have only one reference still and want a new version of it, transform the photo with image to image rather than fusing two shots.
How to combine photos, step by step
- Upload two or three clear stills as JPEG, JPG, PNG, or WEBP, each 20 MB or smaller.
- Write a direct prompt that says how the images should come together, including who or what comes from each file if that matters.
- Complete the security check and click Combine Images once. Leave the tab open while the queued job runs.
- Preview the fused still and download it if the scene is useful. Keep the source photos and the prompt with the result.
What to watch in the preview
Look at hands, edges where two scenes meet, and whether the light feels like one place. A person can be blended into a new background and still carry a shadow that belongs to the old room. If the composition is close but the join is messy, tighten the prompt or start from cleaner, more similarly lit sources rather than trying to fix every seam later.
If you would rather transform one photo with a written instruction, instead of fusing several files, the image to image tool is a closer match. It takes a single upload and a prompt, not a two- or three-file blend.
Look at hands, edges, and any face that should stay recognizable, then run the image combiner again from the original stills if the first merge drifted.
If the mix looks confused
Use fewer competing subjects. Two strong pictures usually combine more cleanly than three busy ones. Crop each source so the important object is large in the frame. Matching the time of day and the camera height helps the model invent one space instead of a patchwork. Stay within the 20 MB limit on every file.
Uploads travel over HTTPS. Files are processed to complete your request and are not sold. Do not combine photos to impersonate a real event or to place someone in a scene they did not agree to.
If one still should simply be edited rather than fused with another, the Flux Kontext tool is often a tighter, single-image path.
After you download the combined image
Open it at the size you will actually use. Check faces, product labels, and the corners of the frame for invented details. If you need a different crop, it is often better to adjust the sources and run the combiner again than to stretch a finished blend. Save the prompt in a text file beside the download so you can rerun a job that almost worked.
When you are building a set of related scenes, keep the same two bases and change only the instruction. That is easier to control than swapping every source on every pass.
Edits that should stay locked to a photo you already like are also covered in the walkthrough to generate or edit images with Flux Kontext.
A short checklist
- Upload two or three JPEG, JPG, PNG, or WEBP files, each under 20 MB.
- Write a prompt that says what each image should contribute.
- Click Combine Images once and wait for the queued preview.
- Download the result if the blend is useful, and keep the source files.
Treat the first output as a draft. A second run from tighter crops and a more specific sentence often beats a long session of retouching a muddy first merge.
Color and scale are worth a look before you upload. A portrait shot close and a landscape shot from far away can be fused, but the person may look pasted unless the prompt says how large they should be in the new scene. If two sources have very different white balance, say which light should win, or correct the stills roughly first. A little preparation in the sources usually saves you a second queued run.
When you are ready, pick two clear stills, write one direct prompt, and save the combined image only after you have checked the joins in the preview.
