Compress image
Shrink image file size right on your machine — pick quality, format and size. Images never leave your machine.
Images are compressed on your machine — no file is uploaded to any server
Compressing images reduces the file size of JPG, PNG, and WebP images so web pages load faster, email/Zalo attachments send more easily, or you can submit an application dossier within a file-size limit — all while keeping quality that looks almost unchanged.
You drag the quality slider, choose an output format (WebP usually gives the smallest file), and compress many images at once in a batch. Everything happens right in your browser on your device — your images never leave the device, free and with no installation needed.

Frequently asked questions
Does compressing images make them blurry?
You stay in control with the quality slider; a balanced level usually cuts file size a lot while the difference is hard to notice with the naked eye.
Are my images uploaded to a server?
Everything runs right in your browser — your files are never uploaded to any server, keeping them completely private.
Which format gives the smallest file size?
WebP usually produces a smaller file than JPG/PNG at the same quality; the tool can suggest WebP automatically.
