Mixed page sizes in a PDF look messy and print badly. This tool fits every page without distortion (contained, centred) into a uniform target size - A4 or US Letter. Typical cases are scanned contracts, brochures, application folders or presentations whose sheets come from different sources and should be unified before printing, archiving or sending.

Just choose the target size (A4/Letter); orientation (portrait or landscape per aspect ratio) is determined automatically. Page content is scaled proportionally, never stretched; blank margins appear where the aspect ratio does not match the target.

Everything runs locally in the browser via pdf-lib. Honestly framed: the tool scales the visible page as a whole (embedded); it does not reflow text or recompute font sizes.

The typical workflow: first bring every page to one uniform format here, then bundle with Merge PDF into a single document - turning mixed scans, tickets and letters into a PDF that prints cleanly in one go. Since content is fitted proportionally, text from smaller originals appears somewhat smaller, but is never cut off or distorted.

FAQ

Is the content distorted?

No, each page is fitted proportionally and centred; where the aspect ratio does not match, a blank margin remains.

Does the text reflow?

No. The tool scales the page as a whole; there is no reflow and no change to font sizes in the text flow.

A4 or Letter?

Both selectable. A4 is the international standard, Letter the US standard.

Is the PDF uploaded?

No, the resizing happens entirely locally in the browser.
