Free Online Image Size Finder With DPI and Print Info

KeepVid Image Size Finder was built for the everyday question of how big an image actually is. Checking dimensions usually means opening a desktop viewer or guessing from a file manager, and most online checkers upload your photo to read it. Our tool runs entirely in your browser, so you can drop in any JPEG, PNG, WebP, or GIF and see its width, height, megapixels, and aspect ratio instantly. It reads the format and file size straight from the file, and detects the DPI embedded in PNG and JPEG bytes to calculate a real print size in inches and centimeters. The core function stays simple: add one image or a whole batch, read the numbers, then copy or export them. A live summary tracks the total count, megapixels, and combined size across everything you loaded. Nothing is uploaded, nothing is installed, and no account is required.

Behind that simplicity are the details people actually need. The print size calculator turns pixels and DPI into physical measurements, so you can confirm whether a photo is ready for a 300 DPI print or only good for the web. Standard size matching compares your image to presets like Instagram Square, YouTube Thumbnail, Full HD, and A4 at 300 DPI, then shows the closest fit and how the aspect ratio lines up. Batch mode stacks many files in one session for side by side comparison, and the CSV export lists every spec for documentation or client delivery. Because all analysis happens locally, your photos never leave your device, which keeps private work safe. In practice, Image Size Finder is used by photographers, designers, and e-commerce teams auditing assets. It is free, works on phones and desktops, and needs no plugins.

Dimensions and Ratio

Read exact width, height, megapixels, and aspect ratio for one image or a full batch the moment you load it.

DPI and Print Size

Detect the embedded DPI from file bytes and convert pixels into print inches and centimeters to judge print readiness.

File Size and Format

See exact bytes, KB, or MB and the true format of every image, so you can check upload limits and optimize assets.

Standard Size Match

Compare your image to presets like Instagram, YouTube, Full HD, and A4 at 300 DPI, then show the closest fit and ratio alignment.

Batch Analysis

Add many images in one session and compare their specs side by side, with a summary of total count, megapixels, and size.

FAQ

Frequently Asked Questions

How do I check an image's dimensions online?

Upload, drag and drop, or paste an image into the finder and it instantly shows width, height, megapixels, aspect ratio, file size, and format. The analysis runs in your browser, is free, needs no account, and works for single images or a whole batch.

Can I see the DPI and print size of an image?

Yes. The tool reads the DPI embedded in PNG and JPEG files straight from the bytes and then calculates the print size in inches and centimeters. If no DPI is stored, it reports that clearly so you know the file has no embedded print resolution.

Does it support batch checking of multiple images?

Yes. Add as many images as you like and they stack in one session so you can compare dimensions, file sizes, and DPI side by side. A summary shows the total count, total megapixels, and combined file size across every image you loaded.

Can I export the results as a report?

Yes. Click Export Report to download a CSV file listing each image’s name, dimensions, ratio, megapixels, format, file size, DPI, print size, and nearest preset. It is handy for documentation, client deliveries, or auditing a folder of web or print assets.

What image formats are supported?

The finder reads JPEG, PNG, WebP, GIF, BMP, and many more, detecting dimensions from the file itself. DPI is read for PNG and JPEG; for other formats the tool still reports size, ratio, and megapixels. All processing happens in your browser with no server involved.

Can it match my image to common sizes?

Yes. Turn on standard size matching and the tool compares your image to presets like Instagram Square, YouTube Thumbnail, Full HD, and A4 at 300 DPI, then shows the closest fit and how well the aspect ratio lines up. Great for quick platform checks.

How do I check an image size before printing?

Upload the file and read the print size line, which converts pixels and DPI into physical inches and centimeters. For crisp prints you generally want at least 300 DPI, so the tool helps you confirm whether the image is ready or needs a higher resolution source.

Is this image size finder free and private?

Yes. It is completely free with no sign-up and no limit on how many images you analyze. All checking happens locally in your browser, so your photos never leave your device and nothing is uploaded, stored, or shared with any server.

Can I paste an image instead of uploading a file?

Yes. Copy an image and press Ctrl plus V on Windows or Cmd plus V on Mac to paste it straight into the analyzer without saving a file first. The tool then reads its dimensions and metadata just like a dropped or browsed file.
