Frequently asked questions about image compression
- What is the difference between JPEG and WebP?
- JPEG is the legacy format, compatible with all browsers. WebP offers better compression (25-35% lighter) at equivalent quality and supports transparency.
- Does compression degrade my image quality?
- At 80% quality, the difference is nearly imperceptible. Use the comparison slider to judge the result.
- Are my images sent to a server?
- No, compression is performed entirely in your browser. No image ever leaves your device.
- How many images can I compress at once?
- There is no limit. You can add as many images as you want and download them as a ZIP.
- What quality setting should I choose?
- For the web, 75-85% offers the best trade-off. For archiving, keep 90-95%. For thumbnails, 50-70% is sufficient.
