Nothing is ever uploaded to a server, so your images stay completely private.

Frequently Asked Questions
Are my images uploaded to a server?
No. All compression happens locally in your browser. Your images are never uploaded, stored, or shared — they stay completely private on your device.
Which image formats are supported?
You can compress JPG, PNG, WebP, and other common image formats. You can also convert your images to WebP, JPEG, or PNG on output.
Will compression reduce my image quality?
You're in control. The quality slider lets you choose how much to compress — higher settings keep images nearly identical, while lower settings save more space.
Why should I convert to WebP?
WebP usually produces noticeably smaller files than JPEG or PNG at the same quality, making it ideal for fast-loading websites.
How many images can I compress at once?
Up to 100 images per batch. They're processed a few at a time to keep your browser responsive, and you can download them all as a ZIP.
Is the tool really free?
Yes — it's completely free with no sign-up, no watermarks, and no usage limits.
