Paper size reference (ISO 216 & North America)
A-series paper follows the √2 aspect ratio: fold an A4 sheet in half and you get exactly A5. Choose the size that matches your source document before converting to avoid scaling surprises.
| Size | Millimeters (W×H) | Inches (W×H) |
|---|---|---|
| A0 | 841×1189 | 33.1×46.8 |
| A1 | 594×841 | 23.4×33.1 |
| A2 | 420×594 | 16.5×23.4 |
| A3 | 297×420 | 11.7×16.5 |
| A4 | 210×297 | 8.3×11.7 |
| A5 | 148×210 | 5.8×8.3 |
| A6 | 105×148 | 4.1×5.8 |
| B5 | 176×250 | 6.9×9.8 |
| Letter | 216×279 | 8.5×11 |

Scan resolution: DPI → pixel dimensions
Higher DPI means bigger images and slower processing. 300 DPI is the sweet spot for OCR and archival scanning of text documents; go higher only for photos or fine print.
| DPI | A4 (px) | Letter (px) | Best for |
|---|---|---|---|
| 72 | 595×842 | 612×792 | Screen viewing |
| 150 | 1240×1754 | 1275×1650 | Draft text scans |
| 300 | 2480×3508 | 2550×3300 | Standard OCR & print |
| 600 | 4961×7016 | 5100×6600 | Fine detail & photos |
Frequently asked questions
Are the PDF converters free to use?
Yes. Local converters run in your browser and are free with no account and no watermark. Tools that need server-side processing (very large files) are covered by the free daily quota, with Pro for heavier use.
Is it safe to convert confidential documents?
Local tools never upload your file — the conversion happens in your browser's memory and nothing is transmitted. Each tool page is labeled Local or Cloud so you always know where processing happens.
PDF to Word, Excel, or CSV — which should I pick?
Word (docx) for prose and reports you want to keep editing; Excel (xlsx) for tables spanning multiple pages; CSV for one flat table to feed another program. If the PDF is a scan, run OCR first.
Is the conversion lossless?
Text, paragraph order and reading order are preserved faithfully. Complex layouts (multi-column magazines, mixed text-and-image pages) fall back to a content stream — each tool page states this before you convert.
