About this tool

Switch a PDF's page size to a standard format like A4 or Letter, or to dimensions you define yourself. It shines when you need to standardize a mix of differently sized pages before printing, move between paper formats for international colleagues, or meet a strict layout spec. Choose from familiar presets or punch in your own width and height; either way, content scales to the new size while aspect ratio and readability hold steady. Prepping files for a print shop, unifying scans that came in at odd sizes, or matching regional paper standards all become straightforward. Privacy is built in by design, because the resizing runs entirely within your browser and your files never touch an external server, keeping even sensitive material yours alone. The output preserves the look and clarity of the source and is available to download as soon as the work finishes. A solid pick for professionals readying documents for print, students bringing assignments to a uniform size, or anyone wanting consistent PDF dimensions.

You can select common presets such as A4 and Letter, or specify your own custom dimensions. This makes it easy to convert between regional paper standards or fit pages to a particular layout requirement for printing or sharing.
No. When fitting pages to new dimensions, the tool preserves the aspect ratio so text and images stay proportional and readable rather than stretched. The result keeps its quality, ready for print shops or standardized assignments.
Yes. If you have scanned pages of varying sizes or a document mixing formats, you can resize them all to one consistent size, which is ideal before sending files to a print shop or unifying a compiled PDF.
It's free with no signup. All resizing runs locally in your browser, so your PDF is never uploaded to any server. Your documents stay confidential on your device from start to finish.
