About This Tool
The Multi-Format PDF Resizer is the ultimate standardizer for cluttered, mismatched corporate documents.
Combining invoices, contracts, and supplementary charts often results in a PDF containing massive A3 ledger pages, standard A4 agreements, and Letter-sized envelopes. Flipping through them is highly distracting, and sending them to physical office printers often causes jam errors due to size mismatch.
This tool rewrites the low-level /MediaBox and /CropBox grids on each page. It maps existing widths and heights, scales original pages proportionally to match target presets (e.g. standard A4), and introduces elegant, consistent surrounding margins, making the entire file look incredibly polished.

Frequently Asked Questions
Will this warp my content?
Never. We support both "Contain" (proportional scaling with white bars) and "Cover" (centered crop). The default Contain mode preserves aspect ratios, preventing distortion.
Will existing forms and annotations remain clickable?
Yes. The algorithm maps the scaling factors to the Annotation coordinate arrays, scaling link boxes, sign boundaries, and inputs to align perfectly after resizing.
Is there a limit on how many pages I can resize?
No. Since all operations run locally in your client sandbox using native JavaScript, you can process extensive PDFs containing hundreds of pages in seconds.
