Frequently Asked Questions
Are my images uploaded to a server?
No. This tool runs entirely in your browser using the HTML5 Canvas API. Your images are never uploaded anywhere.
Which format gives the smallest file size?
JPG and WebP usually produce the smallest files because they use lossy compression. PNG is lossless and stays sharper, but the resulting file is larger.
Will compressing an image reduce its quality?
Some quality is traded for a smaller file size when you use JPG or WebP. Start around 75% quality and adjust until the size and quality balance suits your needs.
Is there a file size limit?
The tool works entirely in your browser, so the practical limit depends on your device's memory rather than a fixed cap. Very large images may take a few seconds to process.
