Exact layout
Spacing, padding, and alignment land on precise pixel positions.

Files stay private while we process them, then they are deleted. Nothing is published unless you choose to share a result later.
Size-checked
Output dimensions are checked before merge so oversized results are blocked early.
Live preview
See order and layout before exporting full-resolution originals.
No metadata surprises
Merged output does not copy conflicting EXIF from sources.

Features
Built for joining images
Horizontal & vertical
Join side by side or stack with match height/width.
Grid layouts
2–4 column presets or custom columns with incomplete-row alignment.
Different sizes
Keep original, fit cells, or fill cells without stretching.
Format control
Reuse converter-quality encoding for JPEG, PNG, WebP, and AVIF.
Rejoin splits
Preset for zero-gap grid merges after Image Splitter.
Progress & cancel
Track merge stages and cancel large jobs.
Horizontal
Merge images horizontally
Place photos left to right with optional spacing. Match Height scales each image proportionally so row heights align without stretching.
Vertical
Merge images vertically
Stack images top to bottom. Match Width aligns column widths while preserving aspect ratio.
Grid
Merge images into a grid
Choose 2, 3, or 4 columns — or set a custom column count. Incomplete final rows can align left, center, or right.
Sizing
How different image sizes are handled
Keep Original Size uses each file's pixel dimensions. Match Height/Width aligns one axis. Fit Cells and Fill Cells target equal grid cells — Fill may crop edges but never stretches.

Questions
Before you upload
Upload at least two images, choose Horizontal, and click Merge Images. Match Height is the default so row heights align.
Yes. Use Match Height for rows, Match Width for columns, Fit Cells for grids, or Keep Original Size for exact pixels.
Not by default. Turn on Allow Upscaling only when you want smaller sources enlarged.
Yes. Use the Rejoin split image preset with pieces in left-to-right, top-to-bottom order, spacing 0, and original size.
No. This joins images in rows, columns, or grids - not a freeform layout or social template editor.
