Frequently Asked Questions
Is this tool really free?
▼
Yes, completely free with no limits and no sign-up. Everything runs in your browser.
Is my data sent to a server?
▼
No. All calculations happen directly in your browser. Nothing you type is ever sent anywhere.
What is DPI?
▼
DPI stands for dots per inch. It measures how many dots of ink a printer places in one inch. Higher DPI means finer detail and sharper prints.
What DPI should I use?
▼
72 DPI is standard for screens. 150 DPI is good for draft prints. 300 DPI is the standard for high-quality photo prints and professional publishing.
How does pixel size relate to print size?
▼
Print size = pixels divided by DPI. A 3000-pixel-wide image at 300 DPI prints at 10 inches wide. At 150 DPI, it prints at 20 inches wide.
Does it show both inches and centimeters?
▼
Yes. The tool shows the physical size in both inches and centimeters simultaneously.
Can I change the DPI to see the effect?
▼
Yes. Change the DPI value and the print size updates instantly. This helps you understand how resolution affects print quality.
Does it update instantly?
▼
Yes. All results recalculate as soon as you change any input.
What pixel dimensions should I use for a 4x6 print?
▼
At 300 DPI, a 4x6 inch print needs 1200x1800 pixels. At 150 DPI, it needs 600x900 pixels.
Is DPI the same as PPI?
▼
DPI refers to printer dots and PPI refers to screen pixels, but they are often used interchangeably. This tool works for both contexts.
What Is Image Resolution Converter?
Image Resolution Converter is a free tool that converts pixel dimensions to physical print sizes in inches and centimeters at any DPI, right in your browser. Enter your image's width and height in pixels, set the DPI, and see exactly how large the image will print. Nothing you type is ever sent anywhere - all math runs locally on your device.
Use it to check whether your image has enough resolution for the print size you need, or to find out how large your photo can print at different quality levels.

Tips for Best Results
300 DPI for quality prints
300 DPI is the standard for photo prints, magazines, and professional publishing. Your image needs 300 pixels for every inch of print.
150 DPI for drafts
150 DPI is fine for draft prints, proofs, and internal documents where perfect quality is not critical.
72 DPI for screens
Screens display at roughly 72-96 PPI. A 72 DPI image is fine for web but will look blurry if printed large.
Quick print size formula
Print size in inches = pixels divided by DPI. A 3000 pixel image at 300 DPI = 10 inches.
Common print sizes
4x6 at 300 DPI needs 1200x1800 px. 8x10 needs 2400x3000 px. 11x14 needs 3300x4200 px.
Try different DPI values
Change the DPI to see how 150, 200, and 300 affect the print size for the same image.
Larger image = larger print
If the print size is too small at 300 DPI, you need a higher resolution image. Enlarging a small image will not improve quality.
Both units shown
Inches and centimeters are shown side by side so you do not need to convert manually.
Results update instantly
Change any input and the print size recalculates immediately.
