Compressing a JPG here does not start with a settings screen. There is no quality slider to guess at, and no trying 60, then 80, then wondering which one looked better. Drop your files in and the same tuned compression runs on each of them automatically.
What comes back is built for what people actually compress JPGs for: getting under an email attachment limit, fitting a platform's upload cap, or shipping images that load faster on a web page.
Select up to 100 JPGs in one session, each up to 15 MB, rather than repeating the same steps for every file. Each image is compressed on its own, so a mixed folder of photos and screenshots comes back correctly instead of being forced through one setting you picked for the first image. Need more than 100? Refresh and start another session — the limit is per session, not per day, so nothing forces you to space the work out.
EXIF, location data and embedded colour profiles are stripped during compression. That trims a little more size, and it means the photos you send are not carrying the coordinates of where they were taken.
Not every JPG re-encodes cleanly on the first attempt — an unusual encoding or a damaged segment can trip up a straightforward pass. When that happens a backup pass runs automatically, trading some quality for the guarantee that you get a compressed file instead of an error. Most files never touch it.
It runs in your browser, so it works the same on a phone as on a desktop. There is no account, no watermark and no email step, and files are removed from the server within the hour.
Want to know exactly how the compression protects colour and detail? Compress JPEG is the same engine with the full explanation. Need a document instead of loose images? JPG to PDF combines them into one file. Other formats are covered by Compress PNG.
