FAQ
Common questions
Does JPG compression reduce image quality?
JPEG compression is lossy. Lower quality settings usually reduce file size more, but can also make compression artifacts more visible.
Are the image dimensions changed?
No. This tool keeps the original pixel width and height and only re-encodes the JPG at the selected quality.
Is my JPG uploaded to a server?
No. The image is decoded and compressed locally in your browser.
Will JPG metadata be preserved?
No. Browser re-encoding creates a new JPG and does not preserve the original EXIF or other embedded metadata.
