JavaScript-Load-Image is a client-side image loading and processing library that focuses on turning File/Blob objects or remote URLs into HTML <img> or <canvas> elements, optionally transformed in the process. It is often used in upload flows where images need to be previewed, resized, rotated, or cropped before being sent to a server, reducing bandwidth and improving user experience. The library can interpret image metadata, including Exif and IPTC tags, and can extract embedded thumbnails when present, which is handy for building fast image pickers or galleries. One of its key capabilities is correcting Exif Orientation, so photos taken on mobile devices appear upright without additional server-side processing. It also offers the option to preserve or restore image headers when resizing, which helps retain metadata or orientation information in the re-encoded image.
