Open a picture and every meaning of "image size" is answered at once: the width and height in pixels as the headline, the file size in KB or MB with the exact byte count, the megapixels, the aspect ratio, the orientation and the format. No upload, no waiting; the numbers appear the moment the image opens, and clicking any value copies it to the clipboard.
People ask how big an image is and mean three different measurements. Dimensions are the width and height in pixels, which decide how sharp an image can look and whether it fits a slot. File size is how many kilobytes or megabytes it occupies on disk, which is what upload limits care about. Megapixels are simply width times height in millions, the camera spec. This tool reports all three side by side, so whichever your form, printer or client asked about, the number is here.
The file size is counted the way Windows counts it: 1 KB is 1,024 bytes and 1 MB is 1,024 KB. A Mac counts in thousands, so the same file can show a few percent larger in Finder. The exact byte count sits right beside the KB or MB figure, so a limit like "under 200 KB" can be checked either way without guessing which one a form means.
The panel also converts the pixel dimensions to a real world print size at 300 DPI, the standard for sharp photo prints, in both inches and centimeters. That answers the classic question of how large a photo can be printed: a 4000 × 3000 pixel shot makes a crisp 13.3 × 10 inch print. For screen use the pixel dimensions themselves are what matter.
Checking a photo against a form's pixel or KB requirements before uploading, verifying what a client or printer sent you, comparing an original with an export, confirming a download is full resolution and not a thumbnail, or settling exactly how many megapixels an old photo really is. One glance covers JPG, PNG, WebP, GIF, BMP, AVIF, HEIC, TIFF, PSD and SVG; the size of an iPhone HEIC, a TIFF scan or a Photoshop file is read from the file itself, so it is answered even where the browser cannot draw a preview of it.
The image is examined entirely in your browser: dimensions, bytes and format are read on your device and nothing is ever uploaded. Close the tab and no trace of the picture remains anywhere.
This page is the identifier for all the basic numbers at once. When one of them is the whole question, the dedicated checkers go deeper: the Aspect Ratio Finder names the ratio (16:9, 4:5, 3:2) and how far a picture is from it, the Megapixel Checker says whether the megapixels are enough for a print or a 4K screen, the DPI Checker reads and changes the DPI stored inside the file, and the PPI Checker works out the resolution at the print size you need.
The measuring family goes further: measure distances, angles, radius and diameter, area and perimeter right on a photo, or all five at once in the full Measure Image tool. The coordinate finder reads exact pixel positions and colors. The full measuring collection shows them all side by side.
Open the image in this tool and everything appears instantly: width and height in pixels, file size in KB or MB with the exact bytes, megapixels, aspect ratio, format and print size. Click any value to copy it, or Copy stats for the full list.
Pixels measure the picture itself: how many dots wide and tall it is. KB and MB measure the file on disk, which depends on both the pixels and the compression. Two images with identical pixel dimensions can differ enormously in KB, which is why forms specify limits for both.
Megapixels are the width times the height divided by a million: a 4032 × 3024 photo is 12.2 MP. The tool calculates it automatically and shows it alongside the other numbers.
Divide the pixel dimensions by 300 for a sharp print in inches; the tool does this for you and shows the result in inches and centimeters. A 3000 pixel side prints crisply at 10 inches. Larger prints are possible at lower DPI when viewed from farther away.
Open it here and the File size line shows it in KB, or in MB for anything over 1,024 KB, followed by the exact number of bytes. Divide the bytes by 1,000 instead if a form counts kilobytes in thousands.
Phones store an upright photo on its side and add a note telling every viewer to turn it. This tool reports the size the way the photo is shown, so a portrait picture reads taller than wide. Some file browsers list the size as stored, with the two numbers swapped; the pixels are the same.
Save the image to your device and open the file here, and you get both its pixel size and its file size. Copying the image in the browser and pasting it here also works for the pixel size, but the browser hands over a freshly made PNG, so its KB will not match the original file.
No. The file is opened and measured entirely in your browser, and nothing is sent to any server. That is also why the numbers appear instantly regardless of how large the file is.
