Frequently Asked Questions
- Why compress to 100 KB?
- 100 KB is a practical target that balances image quality with fast loading times. Many websites and email clients work best with images in this size range.
- Does compressing reduce image quality?
- Yes, JPEG and WebP compression is lossy, meaning some quality is lost to reduce file size. The tool reduces quality gradually using binary search, so the result stays as close to the target size as possible while preserving visual fidelity.
- Are images uploaded to a server?
- No. All processing happens entirely in your browser using the Canvas API. Your images never leave your device.
- What output format should I choose?
- JPEG offers the best compatibility and works everywhere. WebP provides 25-34% better compression at the same quality but may not work with older software. Choose JPEG if you are unsure.
- Is this tool free to use?
- Yes, completely free with no signup, watermarks, or usage limits.
