Resize PDF Pages — A4, Letter, Legal or Custom
Resize every PDF page to a target size while preserving aspect ratio and vector fidelity.
Resize PDF Pages changes the physical dimensions of every page while preserving the visible content. It embeds each source page inside a new page of the target size, scaling and centring so no content is lost.
All processing is 100% client-side. Your PDF is opened inside your browser tab, edited with pdf-lib (and rendered with pdf.js when needed), and saved as a Blob download. Nothing is ever uploaded to any server and closing the tab wipes every working buffer.
- Presets: A4, Letter, Legal, A3, A5
- Custom width × height in points, mm or inches
- Preserve aspect ratio (fit / fill) with centred content
- Uses pdf-lib embedPage — keeps vectors and text sharp
- Runs entirely inside your browser
- 1Upload the PDF.
- 2Pick a preset (A4, Letter, Legal…) or set a custom size.
- 3Choose Fit (safe) or Fill (may crop edges).
- 4Press Resize and download.
- Use “Fit” to guarantee everything is visible; “Fill” may crop edges
- Custom sizes accept mm and inches — the tool converts to points internally
- To crop instead of scale, use the Crop PDF tool
For every page in the source PDF, the tool uses pdf-lib’s embedPage to obtain a vector-based embedded reference. It then creates a new page of the target size, computes a scale factor that fits the source within the target while preserving aspect ratio, and draws the embedded page centred on the new one. The result is a resized document where fonts and vectors stay sharp.
Fit mode (default) scales the source down or up until it fits inside the target rectangle. There may be small margins on two sides if aspect ratios differ. Fill mode scales the source up to cover the target completely, which can crop content on the other two sides. Fit is safer; use Fill only when you know the content will not be truncated.
Resize changes the physical page size and scales content to match. Crop keeps the content the same size but hides parts of it beyond a smaller rectangle. Pick Resize when your goal is to match a paper size (A4, Letter). Pick Crop when your goal is to trim margins.
Your files never leave your browser. All parsing, page rendering and PDF assembly happens locally on your device using open-source libraries (pdf-lib and pdf.js). ilovedigital.in cannot see, store or share the contents of your documents.
