Workflow
A clear order, then one image

Create the composition
Choose a vertical long image or horizontal strip, then prepare PNG or JPG output.
Designed for continuity
The composition stays intentional
No visible gaps
Images meet edge to edge. There is no padding, separator, or decorative background between them.
Order stays under control
The thumbnail queue makes page order easy to inspect before creating the final image.
Built for long screenshots
Vertical composition is the natural fit for PDF pages, chats, receipts, and scrolling captures.
Private by design
The final tool will process image files locally in the browser without uploading them to ToolKnit.
Pro tips
Prepare a better long image
Use images with the same width for the cleanest vertical result. PDF pages already meet this condition.
Review the reading order before export. The first image becomes the top or left edge of the final composition.
For very long output, the final version will calculate a safe browser size before rendering.
