Frequently Asked Questions
- What image format should I use for the web?
- WebP offers the best compression-to-quality ratio for modern browsers. Use JPEG for photographs where wide compatibility is needed, and PNG when you need transparency. Our converter tools make it easy to switch between formats.
- Are my images uploaded to a server?
- No. All image tools on FreeToolStack process files entirely in your browser using JavaScript. Your images never leave your device, making these tools safe for sensitive or private images.
- How much can I compress an image without losing quality?
- Most JPEG images can be compressed 40-60% with minimal visible quality loss. Our image compressor lets you adjust the quality slider and preview the result before downloading so you can find the right balance.
