How does this image compressor work?

Our image compressor uses your browser's built-in capabilities to compress images. Simply drag and drop an image or click to select one, choose your compression level, and click compress. The entire process happens locally on your device — your images are never uploaded to any server.

Is this image compressor really free?

Yes, our image compressor is 100% free to use with no signup required. You can compress as many images as you want without any limits or hidden fees.

Will my image quality decrease after compression?

Our compressor uses smart compression algorithms that minimize quality loss while maximizing file size reduction. At higher quality settings (80-100%), the visual difference is virtually imperceptible. You can adjust the compression level to find the perfect balance between file size and quality for your needs.

What image formats are supported?

We support the three most popular image formats: JPEG (JPG), PNG, and WebP. These formats cover 99% of web and app use cases. The compressor will automatically detect your image format and apply the appropriate compression.

Is my image data safe? Will it be uploaded to a server?

Your privacy is completely protected. All image processing happens locally in your browser using JavaScript. Your images never leave your device — they are not uploaded, stored, or transmitted anywhere. This also means the compression works offline without internet connection.

What's the maximum image size you can compress?

Images larger than 1920 pixels on either side will be automatically resized to fit within that limit while compressing. There's no hard limit on file size, but very large images may take longer to process depending on your device.
