Image Inspector
Image Quality Checker, Analyzer & EXIF Metadata Reader
Upload any image to instantly check its quality, dimensions, DPI, file format, and hidden EXIF metadata; all free, no account required. Works as an image quality tester, JPG analyzer, PNG inspector, color palette extractor, and photo forensics tool in a single pass.
Image Quality Checker, Tester & Property Analyzer in One Tool
Most image editors tell you what you can do to a photo — this tool tells you what is already inside it. Upload any supported file to run a full image quality check in seconds: exact pixel dimensions, true file format, DPI density, brightness and contrast readings, and the complete hidden EXIF metadata block. Use it as a quick image quality tester before sending a file to a commercial printer, or as a picture quality checker to confirm a photo is sharp and high-resolution enough to publish — the results appear on the same page within seconds.
This is a fully free image analyzer — no account, no watermark, no upload limit per session. It works on JPG, PNG, WebP, GIF, BMP, TIFF, ICO, and AVIF files, and returns structured data covering every major image property in a single analysis pass.
This tool returns structured analysis data. It does not alter or transform your original image file.
What Gets Checked
- Image Properties & DimensionsCheck image width, height, exact aspect ratio, file size, and the true underlying format — including detecting if a file has been falsely renamed.
- Image Quality Tester & DPI CheckTest image quality and run a DPI image analyzer check to verify whether your file meets 72 DPI web standards or 300 DPI print requirements — no Photoshop needed.
- Hidden EXIF Metadata & Photo ForensicsView camera model, lens, capture date, software tags, GPS coordinates, and copyright fields embedded in the file — useful for photo forensics online and privacy checks.
- Image Format DetectorDetermine the true file format online even when a file extension has been changed. Detects JPG, PNG, WebP, GIF, BMP, TIFF, ICO, and AVIF by reading the file header directly.
JPG Analyzer, PNG Inspector, and Color Palette Extractor
Different file formats store different amounts of data. Our JPG analyzer reads the compression markers, color space, and full EXIF block embedded by your camera app. The PNG inspector checks the metadata chunk and color profile. For WebP and AVIF, the tool reads the container headers to surface whatever properties the encoder wrote. Regardless of format, you get the same structured breakdown — making it a reliable image format detector online for all common raster types.
The visual analysis layer goes beyond technical headers. Acting as a color palette generator from your uploaded image, it scans the actual pixel data to output dominant colors and accent shades with their hex codes — ready to paste directly into Figma, CSS, or a brand kit. The image size analyzer portion confirms exact pixel counts so you can plan layout slots, social media crops, or print bleed areas with confidence.
What the Analysis Output Covers
A guide to the data categories returned and how each one helps you check or test image quality, properties, and metadata.
| Data Category | What It Reveals | Primary Use Case |
|---|---|---|
| Basic Properties | Width, height, aspect ratio, file size, true format | Check image properties online before upload or print. |
| Quality & DPI | DPI density, brightness, contrast readings | Image quality checker and tester for web (72 DPI) vs print (300 DPI). |
| Color Palette | Dominant colors and hex codes from pixel scan | Extract color palette for brand kits and design files. |
| EXIF Metadata | Camera model, lens, date, GPS, software tags | Photo forensics, copyright checks, and privacy audits. |
Images downloaded from social media often have EXIF data stripped. An empty metadata section is normal for those files.

Frequently Asked Questions
Common questions about checking and testing image quality online, reading EXIF data, analyzing JPG and PNG files, and understanding DPI.
Our image quality checker reads DPI (dots per inch) density, brightness level, and contrast range of the uploaded file. It also confirms the true pixel dimensions, which together let you test image quality and get a reliable picture quality check before printing or publishing. A file with a high pixel count but low DPI will print blurry; this tool flags that combination so you can act before it's a problem.
Upload your file to our free image quality checker. The analyzer reads the file headers and pixel data directly — no Photoshop license required. You get a DPI reading, brightness and contrast scores, exact dimensions, and the full EXIF metadata block in one report, accessible from any browser on desktop or mobile.
Upload the file and click Start Full Analysis. The tool runs an image quality test that reports DPI density, brightness, contrast, and exact pixel dimensions, then flags whether the photo is sharp enough for its intended use. It works the same way as a photo quality tester or picture quality checker — there is nothing to install and no account to create.
Yes. The tool reads the internal JPEG structure including compression markers, embedded ICC color profile, and the full EXIF metadata block your camera or phone wrote at the time of capture. Upload a .jpg or .jpeg file and you will see the same structured property breakdown as any other supported format — dimensions, DPI, color palette, and metadata.
The analyzer reads the actual file header bytes rather than trusting the file extension. This means if someone renamed a WebP file to .jpg to get it past an upload filter, the tool will report the true format as WebP. It supports detection across JPG, PNG, WebP, GIF, BMP, TIFF, ICO, and AVIF containers.
The analysis returns width and height in pixels, true file format, aspect ratio, file size, DPI density, brightness level, contrast score, a dominant color palette with hex codes, and the full embedded EXIF metadata block including camera model, capture date, GPS coordinates if present, and software tags.
It provides the foundational data used in photo forensics: original capture date and time, camera make and model, GPS coordinates, and any software editing tags in the EXIF block. This is useful for verifying the authenticity of a photo, confirming who shot it, or checking if metadata has been stripped or altered. For deeper manipulation detection, a dedicated forensic tool would be needed.
Upload your file and look at the DPI Info section in the results. It reads the DPI value stored in the file header. A result of 72 DPI means the file is screen-optimized and will print poorly at large sizes. A result of 300 DPI means it is ready for high-quality commercial print. If your file shows 72 DPI, resize and re-export from your editing software at 300 DPI before sending to the printer.
Most social platforms — including Facebook, Instagram, and X — automatically strip EXIF metadata on upload. This is a deliberate privacy measure to prevent unintended location sharing and reduces file sizes for faster delivery. If you download a photo from these platforms and analyze it, the metadata section will typically be empty.
Upload your image and the analyzer scans the pixel data to identify dominant and accent colors, returning each one with its exact hex code. Copy those values directly into your Figma file, CSS variables, or brand kit. No manual eyedropper or third-party plugin required.
No. Your image is processed to generate the analysis report and is not stored, indexed, or shared. The tool returns structured data on the page and the session ends cleanly when you close or refresh.
