“

I always wondered why my prints looked blurry — turns out my images were only 72 DPI. ImResizer showed me instantly and I could fix it before sending to the printer.

Super quick way to check if a photo meets the 300 DPI requirement before submitting it. Saved me from wasting a print run.

Frequently Asked Questions

Everything you need to know about image resizing

What is DPI and why does it matter?

DPI stands for dots per inch and describes how many ink dots a printer places per inch of printed output. A higher DPI means more detail and sharper prints. 300 DPI is the standard for high-quality printing, while 72–96 DPI is typical for web and screen display.

How do I check the DPI of an image?

Upload your image to ImResizer's DPI checker. It reads the EXIF metadata embedded in the file and displays the DPI value instantly — no software installation needed.

What DPI do I need for printing?

Most professional printers require at least 300 DPI for sharp, high-quality results. Images below 150 DPI may appear pixelated or blurry when printed. For large-format prints (posters, banners) 150 DPI is often acceptable since they're viewed from a distance.

What DPI is best for web images?

For web and screen use, 72–96 DPI is the standard. Higher DPI values don't improve on-screen quality since monitors display at a fixed pixel resolution, but they do increase file size unnecessarily.

Why does my image show no DPI value?

Some image files — especially PNGs exported from web tools or screenshots — don't store a DPI value in their metadata. In that case, the DPI checker will indicate the value is not set. You can set a DPI using ImResizer's DPI editor.

Which image formats are supported?

ImResizer's DPI checker supports JPG, JPEG, PNG, and WEBP files. EXIF DPI metadata is most commonly found in JPG/JPEG files from cameras and scanners.

Is checking image DPI free?

Yes, checking image DPI on ImResizer is completely free with no account required. No subscriptions, no watermarks, no limits.

Does checking DPI upload my image to a server?

No. All DPI analysis runs entirely in your browser using client-side technology. Your image never leaves your device, making it safe for sensitive photos and documents.
