Image Size Finder

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.
