Features
Canvas ratio
Auto canvas extends by image ratios. Fixed ratios offer centered padding, cropping or stretch, plus gaps, outer padding and rounded corners.
Export settings
Export PNG / JPG / WebP with transparency and lossy quality controls; original images decode one at a time to control memory.
How to use
Choose, drop or paste images, check usable files and arrange their order.
Set direction, canvas ratio and base size; for fixed ratios choose contain, crop or stretch.
Adjust gaps, outer padding, corners and background; expand the preview to inspect layout and order.
Choose format and quality, then export. Regenerate after changing settings or image order.
Limits & processing
Up to 20 images, 20 MB each, 100 MB total. Each source: 16 MP, 8192px side. Output: 32 MP, 16384px side, 32 MB file. Limits are reported, never silently cropped or omitted.
Use cases
Products and tutorials: align detail images vertically with consistent width and spacing.
Comparisons: place before/after images or versions side by side, optionally in equal fixed-ratio slots.
Portfolios and records: join designs or screenshots in order, preserving full content or choosing cropped framing.
FAQ
How do auto length and fixed ratio differ?
Auto adds each image’s proportional length. Fixed ratio sets the canvas first, then divides available space into slots, which may add padding, crop or stretch.
Does it remove screenshot overlap or align content automatically?
It joins by order and layout without detecting duplicate content. For seamless joins, prepare aligned edges without overlap and set gaps, padding and radius to 0.
Why is the canvas or file too large?
Many high-resolution images may exceed memory or tool limits. Reduce base size or count, use JPG / WebP, or resize sources first.
Are animation and source metadata retained?
No. Output is re-encoded as one static image. Resizing and lossy encoding can change detail. PNG can keep transparency; JPG needs a background. Preview is for layout checks.
