Reprints start with one low-res image. Enter pixels and paper size — PaperDPI flags the print-quality risk in seconds, in color. No upload, no image file, works offline.
Reprints start with one low-resolution image.
"Will this still look sharp printed at this size?" That hesitation — mid-meeting, or right before you send files off — is exactly what PaperDPI clears up in a few seconds.
It's simple. Type in the image's pixel dimensions, pick the paper size you're printing on, and PaperDPI estimates the effective DPI/PPI and tells you, in color, whether the resolution holds up.
■ Your client's images never leave the room
PaperDPI doesn't open or upload image files. All it needs is the pixel count, so you can judge a file you've been handed without sending it anywhere.
■ Works with no signal
DPI calculation runs offline. In a print shop or a meeting room with no Wi-Fi, it works just the same.
■ The answer is a color, the moment you type
Type a number and the background changes. Green, you're good to send. Red, take a second look. No button, no waiting.
■ Catches the weak edge most people miss
Orientation sorts itself out. PaperDPI then judges by the weaker of the long and short sides — so a shortfall on one edge won't slip past you just because the other looks fine.
Paper sizes: ISO A-series (A0–A6), B-series (B0–B6), business cards, postcards, and L / 2L photo sizes.
How to read the result:
• Excellent (green) — 300 dpi and up. Commercial print quality.
• Good (blue) — 200–299 dpi. Plenty for posters and flyers.
• Fair (orange) — 150–199 dpi. Fine for large-format or newsprint; may look soft up close.
• Poor (red) — under 150 dpi. Likely to look rough; consider resizing or re-exporting.
No ads. One purchase, and the current features are yours. No subscriptions, no extra unlocks.
Made for print sales reps, DTP operators, and designers who need to answer "will it print?" on the spot.
