Image DPI Checker
Check image DPI online with our advanced scanner that analyzes what is dpi in printing and image files. Instantly reveal each image's current DPI with detailed metadata.
Upload Your Image
Drag & drop or click to select your image (Max 20MB)
Fast DPI Verification
Read metadata instantly and flag files before they reach print or listing.
Header-level inspection
Reads EXIF, JFIF, and PNG pHYs metadata to surface stored DPI values even when files use different measurement units or inconsistent tags across sources.
Instant DPI spotlight
Detected DPI appears in large, clear type so production teams can approve or flag assets at a glance without opening each file or zooming in during reviews.
Multi-file scan list
Drop multiple images and scroll through a consolidated results list without refreshing, perfect for auditing a folder in minutes while keeping names visible.
No-upload audits
Everything runs on-device, keeping pre-release artwork private while you verify technical specs and meet internal compliance requirements for client review.
Format-aware fallback
If metadata is missing, the checker estimates DPI from pixel density to guide your decision before print or listing deadlines when tags are absent entirely.
Direct handoff to conversion
When a value looks wrong, jump to the converter to replace the DPI tag instantly without re-uploading or restarting your workflow or losing momentum midstream.
Check DPI in Three Steps
Upload, inspect, and decide whether the file needs correction.
Upload a file or batch
Select JPG or PNG images and the checker reads metadata immediately, with no sign-in, no uploads, and results in seconds.
Review the detected DPI
Scan the list for stored DPI values and compare them with your print or marketplace requirements before approving assets.
Decide next steps
Keep compliant files as-is, or open the converter to update the DPI metadata in seconds and keep the batch consistent for delivery.
Audit DPI Before It Becomes a Problem
Audit DPI values in seconds so you catch mis-tagged files before print or listing deadlines. Fast, private, and entirely browser-based.
DPI Checker FAQ
Common questions about reading DPI metadata and interpreting results.
It scans file headers for EXIF, JFIF, or PNG pHYs tags and converts units when needed. If those tags are missing, it provides a reasonable estimate based on pixel density so you can decide if correction is required on the spot.
72 DPI is a common default from cameras and design tools and does not automatically mean low quality. It only affects physical size. If the printed size is wrong, use the converter to change the metadata for your target format.
No. The checker is read-only. It inspects metadata in your browser and displays the result without touching pixels, compression, or filenames. Close the page or tab and your files remain unchanged on disk for reference later.
Yes. Add a batch of JPG or PNG files and the results list will show each detected DPI. This speeds up audits for large folders, keeps filenames visible for tracking, and makes handoffs easier when reviewing vendors quickly.
Not exactly. Resolution is the pixel dimensions, while DPI is a metadata value that tells printers how large those pixels should be. Two files with the same pixels can print at different sizes if DPI differs, which changes size previews.
Some exports strip metadata to reduce file size, and some apps omit tags entirely. When that happens, the checker estimates a likely DPI based on pixel density so you can decide whether to add a proper tag before print or upload.
Not yet. The checker focuses on JPG and PNG because they are most common for web and print delivery. Export RAW or TIFF to JPG or PNG first, then run the scan for reliable results and consistent metadata that is easy to verify.
Open the converter, choose your target DPI, and run the batch. It updates the metadata without changing pixels, so you can deliver files that match printer or marketplace requirements quickly and without re-exporting again.
Yes. You can use the tool for free without creating an account, entering a credit card, or installing software. There are no usage caps or watermarks, so you can edit as many images as you like and download full-quality results any time.
No. All processing happens locally in your browser, which means files stay on your device and are never sent to our servers. Once you close the tab, nothing is stored on our side, making it safe for personal and client work.
