Frequently Asked Questions
Is the image compressor really free?
Yes. The tool is 100% free with no sign-up, no watermarks and no usage limits.
Are my images uploaded to a server?
No. All compression happens locally in your browser, so your images never leave your device.
Will compressing hurt image quality?
At a quality setting of around 80%, most images look identical to the original while being far smaller. You control the trade-off with the quality slider.
Which image formats are supported?
JPEG, PNG and WebP are all supported for compression.
Is there a file size limit?
There are no artificial limits. Very large images depend on your device’s available memory, but typical photos process in seconds.
