Step-by-step guide
- Step 1: Select your PDF file.
- Step 2: Choose your target paper size (A4, Letter, A5, or Legal) and fit mode (Fit inside or Stretch).
- Step 3: Click "Resize Pages" to download the uniformly formatted document.
Standardize irregular PDF page dimensions into consistent paper formats (A4, US Letter, A5, or Legal). Choose proportional containment or stretching to prepare files for uniform printing.
"Fit inside" scales pages proportionally and centers them with neat margins. "Stretch" expands the content to match exact dimensions.
No. Pages are embedded as native vector objects inside the new page dimensions, so text sharpness is preserved.
Yes. Each page is adapted to the target dimensions according to the fit algorithm.
PDF Toolbox is engineered with a strict browser-first architecture. All file operations execute entirely in your local browser sandbox via modern WebAssembly and JavaScript engines. No file bytes or sensitive document data are ever uploaded, buffered, or stored on external servers or cloud infrastructure. Memory buffers are cleared immediately when you finish or close your tab.
