Resize PDF pages
Scale all the pages of a PDF up or down by an exact percentage, or automatically fit them to A4 or Letter while preserving the proportions of the original content.
How it works
In "free percentage" mode, every page (content and dimensions) is scaled uniformly by the factor you enter. In "fit to a size" mode, the content of each page is scaled to fit the target size while keeping its proportions, then centered on a page of the exact size you chose.
How is this different from the "Normalize page size" tool?
In addition to the standard A4/Letter fitting, this tool lets you resize by a free percentage (for example, enlarge by 150% for large-format printing).
Does the text stay sharp after resizing?
Yes. The vector content of a PDF (text, shapes, vector images) is redefined mathematically, not rasterized, so scaling doesn't degrade text sharpness the way enlarging a bitmap image does.
The resize calculation runs entirely in your browser with the pdf-lib library — your document is never sent to a server.
