Frequently Asked Questions

What is the output format?

The merged image is saved as a PNG file, which preserves full quality without compression artifacts.

Can I merge images of different sizes?

Yes. Images are aligned and combined regardless of their dimensions. In horizontal mode, images are aligned at the top; in vertical mode, they span the full width.

How many images can I merge?

There is no strict limit — you can merge as many images as your device can handle. For best performance, keep the total under 20 images.

Merging images into a single file is perfect for creating collages, before-and-after comparisons, product showcases, and social media content. TryQuickToolBox's free image merger supports vertical and horizontal layouts with drag-to-reorder — no software installation required.
