Joiner stitches files in selection order onto one canvas. Vertical mode uses the widest width and stacks heights. Horizontal mode uses the tallest height and sums widths. No scaling is applied — pixels stay 1:1 for forensic clarity.
Direction: Vertical suits mobile feeds and before/after. Horizontal suits desktop banners and timelines. Pick the axis where images share similar dimensions to minimize empty gutters.
Order: First selected draws first (top or left). Rename files 01, 02, 03 before upload if your picker shuffles order.
Quality: Export is PNG to preserve text and lines in screenshots. Dimensions can get large with 4 photos — downscale after join if you need a small web file.
Privacy: All stitching runs locally via canvas. Personal comparisons and client work never leave your device.
Limits: 2–4 images, no gap, border, or caption controls. For grids with spacing, finish the joined base here then add padding in Border Adder.
Where it is used

Frequently Asked Questions

- Can I add spacing?
- Not here. Join edge-to-edge, then use Border Adder or Collage Maker for gutters.
- Max images?
- 4 to keep memory safe on mobile. For more, join in two passes.
- Does it resize?
- No. Original pixels preserved. Mixed sizes align top-left, with narrower rows left-aligned.
