Frequently Asked Questions

Q: How does compression quality affect the image?

Lower quality produces smaller files but may introduce visible artifacts. Our slider lets you find the perfect balance between file size and visual quality.

Q: Will compression reduce the image dimensions?

No. Image dimensions (width × height) stay exactly the same. Only the file size is reduced through encoding quality adjustment.

Q: Which format should I choose?

JPG is best for photographs, PNG for graphics with transparency, and WEBP for the best balance of quality and size in modern browsers.

Q: Is my image uploaded to your servers?

No. All compression happens in your browser using Canvas API. Your images never leave your device.
