Common questions
Compress JPG FAQ
Is JPG compression lossless?
No. JPEG encoding is lossy, so lower quality settings discard more visual detail.
Will every JPG become smaller?
Not necessarily. An already optimized source can be similar in size or even smaller than a new browser export.
Does the output retain EXIF data?
No. Canvas export creates a new image without the source JPG's embedded EXIF metadata.
