Frequently Asked Questions

How does this image compressor work?

Our image compressor processes everything directly in your browser using the HTML5 Canvas API. Your images are never uploaded to any server — the compression happens locally on your device, ensuring complete privacy.

What image formats are supported?

You can compress JPG, JPEG, PNG, WEBP, GIF, and BMP images. You can also choose to output in JPEG, WEBP, or PNG format.

How many images can I compress at once?

You can compress up to 10 images at a time. Simply drag and drop or select multiple files.

What does the compression quality slider do?

The quality slider lets you control the trade-off between file size and image quality. Lower values produce smaller files but with some quality loss. Higher values maintain better quality but result in larger files. A value of 60-80% is typically a great balance.

Is this tool really free?

Yes, 100% free with no sign-up, no watermarks, and no usage limits. All processing happens in your browser.
