How to merge images
- Add 2–9 images. Drop, browse or paste — nothing leaves your browser.

- Download. Export a single PNG or JPG at full resolution.
Three modes, three use cases
Two images
Classic side-by-side or stacked merge — screenshots, comparisons, chat records.
Grid collage
Up to nine images in rows and columns with optional per-cell labels — ideal for putting outputs from different AI models side by side with their names.
Before / After
Two aligned images with a draggable divider and editable labels — for edits, filters, renovations and AI upscaling showcases.
Frequently asked questions
How do I merge two images into one?
Drop both images in, pick “Two images” mode and choose horizontal or vertical. Spacing, background and border are adjustable — export one PNG or JPG.
How many images can I combine at once?
Grid mode takes 2–9 images with custom rows and columns. For more than nine, merge in batches then combine the results.
How do I make a before/after comparison?
Pick “Compare” mode and add two images — you get a divider-line comparison with draggable split position and editable BEFORE/AFTER labels.
Can I use it to compare AI model outputs?
Yes. In grid mode enable per-cell labels, name each cell after a model (e.g. Midjourney, Kling) and turn on the header strip for the shared prompt — a standard model comparison collage.
Will merging reduce image quality?
PNG export is lossless; JPG quality is adjustable. Each image is scaled proportionally inside its cell — never stretched.
Are my images uploaded?
No. Merging runs entirely in your browser with Canvas — it even works offline after the page loads.
