Content will be scaled to fit.
Fit your document to any paper. Our Resize PDF tool allows you to change the physical page dimensions of your PDF file (e.g., from A4 to Letter) while automatically scaling the content to fit perfectly.
What is PDF Resizing?
PDF pages have defined widths and heights, usually measured in points or inches. Resizing involves creating a new page canvas with different dimensions and "drawing" the original page content onto it, often shrinking or enlarging it to fill the available space.
How it Works
We take your original page and treat it like an image. We calculate the best fit for your chosen target size (maintaining the aspect ratio) and center the content on the new page size, adding white margins if necessary.
How to Change PDF Page Size
- Upload: Select the PDF you need to resize.
- Choose Size: Pick a standard preset format like A4, Letter, or Legal.
- Download: Get your newly formatted document ready for printing.
Key Features
- Auto-Scaling: Prevents content from being cut off by shrinking it to fit.
- Standard Presets: Supports ISO sizes (A3, A4, A5) and US sizes (Letter, Legal).
- Quality Preservation: Vector text and images remain sharp even when resized.
Supported Sizes
- A4: The standard size for most of the world (210 x 297 mm).
- Letter: The standard for US office documents (8.5 x 11 in).
- Legal: Longer paper often used for contracts (8.5 x 14 in).
When to Resize?

- Booklets: Shrinking pages to A5 for creating pocket-sized handouts.
- Posters: Scaling a flyer up to A3 for larger visibility.

Frequently Asked Questions
Will my text get fuzzy?
No. Since PDFs use vector graphics, resizing them up or down keeps the text perfectly crisp.
Does it distort the image?
We maintain the aspect ratio (width vs height) so your content doesn't look stretched or squashed.
Can I set a custom size?
Currently we support standard presets. Custom sizing is coming in a future update.
