Some print services, scanners, and professional workflows require 600 DPI. This tool sets your JPG or PNG to exactly 600 DPI by rewriting the file header — pixels untouched, zero quality loss, nothing uploaded.
The DPI field is preset to 600. Drop the file, click convert, download.
Most consumer printing looks sharp at 300 DPI. 600 DPI is required or recommended in specific professional contexts where fine detail, tiny text, or very close viewing distances are involved. Common 600 DPI use cases:
Flatbed and film scanners default to 600 DPI for archival-quality scans. Submitting or receiving scan files at 600 DPI preserves maximum detail from the source.
Gallery-quality giclée prints on canvas or fine art paper are typically produced at 600 DPI or higher to reproduce brushstrokes and fine textures at close viewing distance.
Radiology reports, pathology slides, and research figures submitted to journals often require 600 DPI to ensure diagnostic detail is preserved in print.
Text documents with small fonts (under 10pt) need 600 DPI for perfectly sharp character edges. OCR software also performs better on 600 DPI input.
The tool reads the current DPI from the file header and shows it before you convert.
Type 600 or click the 600 preset button. You can also enter any other value if needed.
Only the density header changes — JFIF and EXIF resolution fields for JPEG, the pHYs chunk for PNG. Every pixel stays identical.
Same image, same quality, 600 DPI header — accepted by professional print services and archival systems.
| Print / output size | Pixels required at 600 DPI | Pixels at 300 DPI (for comparison) |
|---|---|---|
| 4 × 6 in (10×15 cm) | 2400 × 3600 px | 1200 × 1800 px |
| 5 × 7 in | 3000 × 4200 px | 1500 × 2100 px |
| 8 × 10 in | 4800 × 6000 px | 2400 × 3000 px |
| A4 (8.3 × 11.7 in) | 4961 × 7016 px | 2480 × 3508 px |
| 2 × 2 in passport photo | 1200 × 1200 px | 600 × 600 px |
| Letter / journal figure | 5100 × 6600 px | 2550 × 3300 px |

Unlike tools that re-encode the image, this rewrites only the metadata header. Every pixel byte stays identical — no compression artefacts introduced.
See the current DPI in your file before changing it — useful for diagnosing why a professional system rejected your submission.
DPI conversion happens in your browser. Sensitive artwork, medical images, and archival documents never leave your device.
No queue, no processing wait — header rewrite completes in milliseconds even for files over 50 MB.
