Despre acest instrument
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.
