About this tool
Compress JPG Keep EXIF is a free online tool. Compress JPG while keeping shooting EXIF metadata.
After uploading a JPEG file, you can adjust the compression quality (1-100), and the tool will display a comparison of file size before and after compression and a preview of image quality. The key function is to retain EXIF metadata (camera model, shooting time, GPS location, etc.) of the original image, which ordinary compression tools typically discard. Support batch uploading of multiple pictures and unified compression.
JPEG compression is achieved by re-encoding image data using the Canvas 'to Bob ("Image/jpeg', Quality) method. EXIF retention requires special handling: first read the EXIF data blocks of the original file, compress the image, and then write it again. The tool does all operations locally in the browser and does not upload files.
It is suitable for photographers to compress and archive photos while retaining the shooting information, or reduce the size of online pictures without losing copyright information. Ordinary compression tools discard EXIF, but this tool specifically solves this problem.
The online JPEG compression tool (retaining EXIF) compresses the volume of JPEG pictures while retaining shooting parameter metadata, supporting batch processing and image quality adjustment.
