FAQ
Which image formats are supported?
- JPG compression / JPEG compression (image/jpeg): Best for photo compression
- PNG compression (image/png): Supports transparency, can be converted to JPG or WebP for higher compression ratio
- WebP compression (image/webp): Efficient image compression format that reduces file size while maintaining quality
How can I balance file size and image quality?
Use the "Compression Quality" slider to adjust the output quality in real time. In most cases, a quality setting between 75% and 85% provides a good balance between visual quality and file size reduction. You can compare the before-and-after previews to find the setting that works best for your image.
Will this tool change the image dimensions or resolution?
No. This tool reduces file size by adjusting image quality only. The original width and height of the image remain unchanged.
Are my images uploaded to a server during compression?
No. All image processing is performed locally in your browser using the Canvas API. Your images never leave your device and are not uploaded to any server, ensuring complete privacy.
