How to check an image size

  1. Choose or drop an image into the checker.
  2. Read its exact file weight and pixel dimensions.
  3. If it is above your upload limit, open the image compressor and enter the required KB or MB size.

File size and dimensions are different

File size measures storage weight in bytes, KB or MB. Dimensions measure the number of pixels across and down the image. An upload form can check either rule—or both—so confirm every requirement before submitting.

Private by design

The checker reads the file through browser APIs on your device. PixSqueeze does not upload the image, store a copy or send its name to analytics.
