Frequently Asked Questions
Does compressing to 1MB reduce image quality?
Yes, some quality reduction is inevitable when compressing to a specific file size. However, our binary-search algorithm finds the highest possible quality that still meets your 1MB target, so quality loss is minimized.
Is my image uploaded to a server?
No. All processing happens entirely inside your web browser using the HTML5 Canvas API. Your images are never sent to any server, never stored anywhere, and never seen by anyone other than you.
How do I compress an image to 1MB for a website?
Upload your photo to this tool with the 1 MB preset selected. The tool will compress your image to under 1MB while keeping the highest possible quality. The resulting JPEG is perfect for websites, portfolios, and any use case where you need a good balance of quality and file size.
