Frequently asked questions
How much can I reduce my image file size?+
Depending on the original image and quality setting, you can reduce file sizes by 50–90%. Photos with lots of detail compress well at quality 60–80, while simpler graphics can go even lower without noticeable loss.
Does compressing an image reduce its quality?+
Compression always involves a trade-off between file size and quality. At higher quality settings (70–90), the difference is virtually imperceptible. Use the before/after comparison to find the sweet spot for your needs.
What image formats are supported?+
You can upload JPG, PNG, and WebP images. You can also convert between these formats during compression — for example, convert a PNG to WebP for even smaller file sizes on the web.
Are my images uploaded to a server?+
No. All image compression is performed entirely in your browser using the Canvas API. Your images never leave your device, ensuring complete privacy and security.
Can I compress multiple images at once?+
Yes! You can upload and compress multiple images in a single batch. Adjust the quality and format settings, then download each image individually or all at once as a ZIP archive.
