  • Convenient preview of files, immediately after dragging pages into the editor area. Moreover, you can place the desired pages in any order – a great opportunity thanks to which this online service outperforms competitors who do not allow changing the order during the merge process.
  • The speed of the program when processing files was a pleasant surprise. Processing two 2MB files took about 10 seconds! It seems more time was spent on choosing disk space and thinking about which files to use for testing. The merge tool is really nimble.

Other features of Smallpdf include converting between PDF and all office formats doc, xls, rtf, ppt. In addition, the service easily performs PDF splitting and works well with resetting and protecting pdf files.
