What is Probe-Image-Size?

Probe-Image-Size is a free and open-source API that allows JavaScript developer to get the image size of the image without actually downloading the image. The API is small in size and works with remote and local data without any heavy dependencies. The API is effective with large images, reduces memory, increases processing speed and downloads minimal data from the remote. In the output data, the API provides the width and height of the image before any transformations like orientation and cropping are applied.

The API currently supports getting file size of JPEG, GIF, PNG, WebP, BMP, TIFF, SVG, PSD, ICO, AVIF, HEIC and HEIF. Formats like JPEG & TIFF can store size anywhere. Always provide full file content to sync methods, if you want to guarantee the file size.
