Image Dimensions Checker

Instantly see the exact width, height, megapixels, aspect ratio, file size and format of any image. Drop in several files to compare them side by side — nothing is uploaded anywhere.

How to use Filesvo

  1. Select or drop image files, or paste an image from your clipboard.
  2. Read each file's dimensions, megapixels, aspect ratio, size and format from the table.
  3. Add more files to compare, or clear the list and start over.

Why image dimensions matter

Pixel dimensions determine where an image can be used: profile photos, print layouts, app store listings and ad platforms all specify required or minimum sizes. Checking the real dimensions before uploading saves rounds of rejected files.

The aspect ratio — the proportional relationship between width and height — decides whether an image fits a slot without cropping. A 16:9 image fills a video thumbnail exactly; a 4:3 or 1:1 image in the same slot gets cropped or letterboxed. Filesvo reduces each image's ratio to its simplest form so you can match it against requirements at a glance.

Private by design

Your files are processed directly in your browser using the browser's built-in image APIs and are not uploaded to Filesvo. Nothing is stored on our servers, because nothing ever reaches them.

Frequently asked questions

Which formats can I check?
JPG, PNG, WebP, GIF, BMP and AVIF — anything your browser can decode. The dimensions come from actually decoding the image, not from reading file headers, so the numbers are what any app will really see.
What are megapixels?
One megapixel is one million pixels — width multiplied by height. A 4000 × 3000 photo is 12 MP. Megapixels are a quick way to compare overall resolution across images with different shapes.
How is the aspect ratio calculated?
The width-to-height ratio is reduced to its simplest whole-number form, such as 16:9 or 4:3. When an image doesn't reduce to a clean ratio, Filesvo shows the decimal ratio instead, like 1.85:1.
Are my images uploaded to check their size?
No. The images are decoded by your own browser and the numbers are computed on your device. Nothing is sent to Filesvo.
