Build a comparison or a sequence of screenshots

Use a horizontal arrangement for a before-and-after pair, or a vertical arrangement for a reading sequence. Reorder the inputs before processing. Matching image sizes rescales their pixels; it does not reflow text inside screenshots.

Plan the canvas before adding more images

Spacing and large source images increase the final canvas area. If the pixel budget is exceeded, resize the sources first. Inspect small labels at 100%. The output is a single raster image, not a multipage PDF or an editable document.

A simple path to the right image

01

Start with your original

Choose your photos or try the sample. Your files stay on your device.

02

Make it your own

Arrange two or more images in order. Choose the direction, spacing and background, then save a single PNG.

03

Check, then download

Compare both versions and inspect at 100%. Download one result or the whole batch.

A few useful details

Can I choose the order of the photos?+

Yes. Arrange the images before processing and choose horizontal or vertical layout. Check spacing and background in the combined result.

Will merging create an animation?+

No. The result is one PNG image. Use a GIF tool when you need motion rather than a static collage.

Will my image keep its quality?+

Arrange two or more images in order. Choose the direction, spacing and background, then save a single PNG.

Are my files uploaded?+

Non-AI tools process files locally in your browser without uploading them or requiring an account. AI tools use remote processing and are clearly labeled. Files are uploaded only after you explicitly confirm; local tools never switch to cloud processing automatically.
