Frequently Asked Questions
Q:
Are my images uploaded to a server?
No! All image compression happens entirely in your browser using JavaScript. Your images never leave your device, ensuring complete privacy and security.
Q:
What's the maximum file size I can compress?
Each image can be up to 10MB. For larger files, consider compressing them first or splitting into smaller images.
Q:
Which format should I choose?
JPEG is best for photographs, PNG for images with transparency or text, and WebP for the best compression with modern browser support.
Q:
What quality setting should I use?
80% is recommended for most use cases. Use 90-100% for high-quality prints, 60-80% for web images, and 40-60% for thumbnails or previews.
Q:
Can I compress PNG images without losing quality?
Yes! You can compress PNG images and optionally convert them to JPEG or WebP for even better compression. Note that converting to JPEG or WebP will remove transparency.
