Frequently Asked Questions

How do I change my PDF page size to standard A4 or US Letter?
Upload your document, select your target paper size (e.g., A4 or US Letter), choose a scaling method (Fit & Center, Expand Canvas, or Stretch), and click 'Apply Page Resize'. The tool converts all pages to uniform dimensions.
Can I define custom page dimensions in millimeters or inches?
Yes! Click the 'Custom Size' preset button to input your exact custom width and height in millimeters, inches, or points.
Will changing page dimensions distort my text or images?
No. When using our default 'Fit & Center' mode, the original page content is scaled proportionally with balanced margins, preserving sharp text, signatures, and correct vector ratios.
Can I resize the document to meet strict portal KB limits?
Yes! You can switch between 'Paper Dimensions Mode' and 'File Size (KB/MB) Mode' to meet the upload constraints of government, university, or employment portals.
Are my sensitive documents uploaded to any remote server?
No. All PDF page parsing, vector rescaling, and compilation execute 100% locally inside your device browser memory.
