Frequently Asked Questions
How do I combine images vertically or horizontally?
First, upload your images. Then, toggle the alignment mode: select **Vertical Column** to stack them top-to-bottom, or **Horizontal Row** to align them left-to-right. Rearrange the layout order by dragging the file items, and click Compile to save the unified file.
What happens if my images have different aspect ratios?
If images have different widths or heights, they may look uneven. Simply toggle our **Auto-Resize** feature, which automatically upscales or downscales all merged images to cleanly match the width (for vertical layouts) or height (for horizontal layouts) of the largest source photo.
Can I inject padding spacing gaps between combined photos?
Yes, you can adjust the spacing slider in the options dashboard to inject gaps (from 1px to 100px) between stitched elements. You can also customize the background color of these gaps to match your page or template layout.
Is there a maximum limit to the number of images I can merge?
SimplyUtils lets you combine up to 50 image assets simultaneously into a single high-resolution canvas. The only limits are based on your web browser's maximum canvas memory allocation.
