Frequently Asked Questions
Will my text be distorted?
No, by default we maintain the 'Aspect Ratio' of your content, adding white space (margins) if needed. You can choose to 'Stretch' if you want to force it to fill the page.
Can I resize to a custom size?
Yes, select 'Custom' in the dropdown and enter your specific Width and Height values.
Does it reduce file size?
Resizing changes the page definition ('MediaBox'), but doesn't necessarily compress images. Use our 'Compress PDF' tool if you need a smaller file size.
