How to print a long screenshot so you can read it

The trick to printing a long screenshot is to cut it up and set it in columns: split the image between lines of text and place the pieces side by side, two or three per A4 page, each wide enough to read. Add your screenshot to the long screenshot printing tool and all of this happens automatically.

Why printing it directly fails

A scrolling screenshot from a phone can be ten screens long or more. Squeeze that onto one page and the image may end up only 10–20 mm wide, with text under 2 pt: impossible to read. Cutting and arranging it by hand in an image editor is slow, and it’s easy to slice through a line of text.

How the tool handles it

  1. Detects it. Any image more than three times as tall as it is wide is treated as a long screenshot. There’s no mode to choose.
  2. Finds safe cuts. Screenshots usually have a plain background, so the tool scans row by row and cuts only in the blank gaps between lines.
  3. Sets the column width. Text in a phone screenshot is roughly 4–5% of the image’s width. To print it at about 8–9 pt (newspaper body text is around 9 pt), each column needs to be at least about 65 mm wide, which is why a page usually holds two or three columns.
  4. Adds pages. When one page isn’t enough, more are added and exported together.

Special cases

Printing and saving

Click Export to print, download a PDF, or download one 300 DPI image per page. Before export, the tool checks text sizes and warns you about anything below a readable size. Everything happens in your browser; your screenshots are never uploaded. For the best results, print with Actual size or 100% so the columns keep their width.

Open the long screenshot page and add your screenshot to try it.
