Questions

Join Image Files: common questions

Can I change the order?

Yes. The queue supports rearranging images before joining.

Can I join images side by side?

Yes. Choose horizontal or vertical layout.

Do all images need the same dimensions?

No. The tool aligns images on the long edge and pads any size mismatch, so screenshots, photos, and graphics of different sizes can be combined without manual resizing.

Are my images sent to a server?

No. Joining happens locally on the canvas, so your originals and the finished image never leave your browser.

Will this tool stay free?

Yes. Everything this tool does is free. On some tools, a Day or Project Pass raises the file-size and batch limits if you need more.
