Why Compress JPG?
Most JPGs are saved at unnecessarily high quality. Your camera or phone probably uses 95-100% quality by default, which produces great-looking images but massive files. Reducing to 80% typically cuts file size by 60-80% with changes invisible to the naked eye.
We use libvips with optimized encoding settings—the same approach used by major CDNs and image optimization services. The output is a standard JPG that works everywhere.
This is different from format conversion. If you want even smaller files, consider converting to WebP or AVIF. But if you need to stay in JPG format (for compatibility or specific requirements), compression is your friend.
Frequently Asked Questions
Depends on the original quality. If it's from a camera at 95% quality and you compress to 80%, expect 60-80% size reduction. If it's already been compressed, savings will be smaller. We show you before/after sizes so there are no surprises.
At 80% quality, no. JPG artifacts become visible around 60-70% quality, and even then only if you're looking closely. For web use, 80% is the sweet spot—visually identical to the original at a fraction of the size.
You can, but you'll get diminishing returns and potentially introduce artifacts. Each compression cycle degrades quality slightly. If your image has already been heavily compressed, there's not much more to squeeze out.
Compression keeps the JPG format—useful when you need compatibility or the recipient specifically needs JPG. WebP conversion changes the format but achieves even smaller sizes. If format doesn't matter, WebP or AVIF will give you better results.
By default, we preserve essential metadata like color profiles. EXIF data (camera info, GPS, etc.) is stripped to reduce file size and protect privacy. Pro users can choose to keep or remove specific metadata types.
