Frequently asked questions
What is the recommended JPEG quality setting for web use?
A quality level between 75% and 82% offers the optimal sweet spot, delivering file size reductions of 60% to 80% while remaining visually indistinguishable from the uncompressed original.
Does JPEG compression strip camera EXIF data to save bytes?
Yes, our compressor strips non-essential metadata such as GPS coordinates, camera serial numbers, and thumbnail caches, which alone can save between 10KB and 60KB per photo.
Can I re-compress a previously compressed JPEG?
You can, but repeated lossy re-encoding can compound compression artifacts. We recommend compressing from the original high-resolution photo whenever possible.
