How Does This Work?
This tool compresses images by re-encoding them as JPEG with an adjustable quality setting. Lower quality = smaller file size but more compression artifacts. A quality of 80% typically provides a good balance between file size and visual quality. All processing happens in your browser using the HTML5 Canvas API. Your images are never uploaded to any server.
Frequently Asked Questions
Does compressing reduce image quality?
JPEG compression trades some quality for smaller file size. At 80% quality, the difference is barely noticeable. Below 50%, artifacts become visible.
What formats are supported?
You can upload any image format (PNG, JPG, WebP, GIF, BMP). The output is always JPEG since it provides the best compression ratio for photos.
Is there a file size limit?
No! Since all processing happens in your browser, there are no server-imposed limits. Very large images may take a moment to process depending on your device.
Are my images uploaded to a server?
Never. All compression happens locally in your browser using the Canvas API. Your images never leave your device.
