Why DPI matters for perfect prints
What is DPI?
DPI (dots per inch) tells printers how dense to place ink dots. A 300 DPI image prints at 300 dots per inch — the gold standard for magazines, flyers, and photo books.
Recommended DPI values
- 200 DPI – Suitable for large banners or drafts
- 300 DPI – Professional photos, brochures, magazines
- 600 DPI – Fine art and high‑detail reproductions
How our tool works
We modify the image metadata — EXIF for JPEG, pHYs chunk for PNG — without altering a single pixel. Your file size stays nearly identical and quality remains untouched.
100% private & fast
All processing happens in your browser. Your images never leave your device — ideal for confidential documents, client work, and quick adjustments.
Pro tip: Check print dimensions first
Divide your pixel dimensions by DPI to get the print size in inches. For example, 3000×2400 px at 300 DPI = 10″ × 8″. Use this tool to verify dimensions before sending to a printer.
