Are my images uploaded to a server?

No. All compression happens locally in your browser using the Canvas API, so your files never leave your device. You can even turn off your Wi-Fi and it still works.

How much smaller will my images get?

It depends on the photo and the quality setting, but JPEG and WebP compression commonly cuts 50 to 80 percent off a typical photo. Each result shows the exact before and after size.

Does compressing remove EXIF and location data?

Yes. Re-encoding through the browser strips EXIF metadata, including GPS location, which is a privacy bonus on top of the smaller file.

Can I compress many images at once?

Yes. Add as many as you like; they are queued and compressed together, and you can download everything as a single ZIP file.

Is there a file size or count limit?

There is no artificial limit. Very large photos are resized automatically to fit the browser's canvas limit, and the result is flagged when that happens.
