FAQ
Which image formats are supported?
Supported image compression types:
- JPG compression / JPEG compression (image/jpeg)
- PNG compression (image/png): To achieve stronger compression effects, images will be converted to JPG after compression by default, so transparency will not be preserved.
- WebP compression (image/webp)
- GIF compression (image/gif)
- BMP compression (image/bmp)
- AVIF compression (image/avif)
- SVG compression (image/svg+xml): SVG vector images are not recommended for this compression tool, as they will be converted into raster images after processing, causing loss of vector properties.
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.
