How to scale

  • Open Scale PDF and add your file.
  • Move the slider or press a quick size such as 50% or 150%.
  • Press Scale PDF and download the result.

Scale or change page size?

Scale PDF makes the whole page bigger or smaller by a percent. Change PDF Page Size fits content onto a standard size such as A4 or Letter.

Good to know

  • Text stays text, so it can still be selected and searched.
  • Scaling up does not add detail to pictures that were small.
  • Use 71% to shrink A3 pages to A4 size, and 141% for the reverse.
