Screenshot One Pro

Take awesome, whole webpage screenshots in batch.

Screenshot One Pro makes full-length screenshots of webpages much larger than your screen resolution – in batch! It’s straight-forward, and does not contain advertisements!

Enjoy its batch functionality: Submit an entire list of webpages and, with one click, Screenshot One Pro will make screenshots of all pages in the list! The length and width of each screenshot is fully customizable.

Save as PNG, GIF or JPG/JPEG. You can add a PNG or GIF watermark from anywhere on the web, and give each snapshot a custom file name.

  2. Choose a custom resolution or select one of the presets to define the resolution of the snapshot.
  3. If you want: select a file type and name your snapshot. Also: Paste or type the URL to a watermark on the web.
  4. The web capture is now saved to your picture gallery. Screenshot One Pro can now open the app of your choice to share or edit the image.

CLI / PowerShell script use

All switches are optional, but the more you use, the higher the potential degree of automation. Please note, that the order in which the CLI switches are used is currently important in relation to the correct operation of the software. If you choose to use the -m switch (watermark), it always has to be the last switch in line.

Schematic example

ScreenshotOnePro -t [PNG, JPEG, GIF, TIFF or BMP] -u [URL] -h [height] -w [width] -d Y -v [IE emul. version & mode] -r [naming reference] -l [Full path to desired output folder] -m [full path to watermark file]
