Combine PDF Pages Into One Long Page

PDF To Single Page stacks every page of a PDF vertically onto one tall page. Its width is that of the widest page and its height is the sum of the page heights. It is a strip, not several pages per sheet.

Drag and drop files here, or click to choose

Accepts PDF · up to 500.0 MB per file · up to 20 files at once

You can also paste a file with Ctrl/Cmd+V, or from the clipboard menu.

To Single Page stacks every page as Form XObjects on one tall page. Width is the maximum page width; height is the sum of page heights. Horizontal scale may stretch narrower pages to that max width.

There are no parameters. Password-protected files are unlocked for you on this page once you enter the password; API callers run Unlock first. Very long stacks can produce a page some viewers refuse to render.

This is not N-up imposition (several pages per sheet) and not a contact sheet. It is a vertical strip.

If you need separate files, use Split. If you need overlays, use Overlay PDFs.

Features

  • One page; Form XObjects stacked by height
  • No options; native lopdf
  • May stretch narrower pages to max width
  • Anonymous API at /api/v1/general/pdf-to-single-page

When to use this tool

  • Make a long strip for a timeline screenshot
  • Feed a single-page pipeline that rejects multi-page files
  • Compare a short form as one scroll

How do I put all PDF pages on one page?

  1. Upload a PDF.
  2. Click Process. There are no fields.
  3. Download the PDF and confirm page count is 1.
  4. Scroll the long page; some mobile viewers choke on huge heights.

Limits and edge cases

  • Vertical stack only
  • No gap or N-up control

Frequently asked questions

Will two A4 pages become one A3 sheet side by side?
No. They stack vertically. Width is max(page widths).
Does text stay selectable?
When the original pages had text objects, the form XObjects still contain them. Viewers vary.
Is there a page limit?
No hard cap in the op. Practical limits are memory, time, and viewer maximum page size.
Can I choose a gap between pages?
No. Heights are summed with no spacer option.
