DPI only means something at a print size. Tell us how large you want to print below, drop the image, and see the effective resolution - or just upload for the full measurement report. Files are deleted after processing.
Optional - tune the checks to your product. Locked once files are submitted.
Your report and proof appear here after you upload a file - free, no signup.
Filecheck runs this check automatically on every customer upload - on your store, before bad files reach your queue.
Automate this on your store →Filecheck does it automatically for every customer upload - on WooCommerce, Shopify, PrestaShop, OpenCart, or any site - before a bad file ever reaches your queue.
Optional but recommended: the width and height you plan to print at. Effective DPI = pixels ÷ print size, so the same image can pass as a flyer and fail as a poster.
The report shows pixel dimensions, the effective DPI at your target size, color space, bit depth and format - the full inspection, not just one number.
300 DPI is the magazine-quality benchmark, but banners viewed from meters away print beautifully at 100. You set the bar; we do the math. Free, no signup.
It depends on viewing distance. 300 DPI is the standard for handheld print (cards, brochures, magazines). Posters are fine at 150–200. Large banners viewed from a distance work at 72–100. This tool computes your image’s effective DPI at the size you enter, so you can judge against the right bar.
Pixels divided by print size. A 3000px-wide photo printed 10 inches wide is 300 DPI; the same photo printed 40 inches wide is 75 DPI. The number stored inside the file’s metadata is irrelevant - what matters is pixels versus the physical size you print at.
Not necessarily. The DPI tag in a file is just metadata and changes nothing about the pixels. A 6000×4000px photo “at 72 DPI” still prints magazine-sharp at 20×13 inches. Check effective DPI at your print size instead - exactly what this tool does.
This checker measures; it does not upscale. Filecheck’s workflow engine includes AI upscaling as an auto-fix for customer uploads - that is part of the paid product for your own site.
