Frequently Asked Questions
Q: What is WebP format?
WebP is a next-generation image format developed by Google. It can reduce file size by about 30% compared to JPEG and PNG while maintaining equivalent quality. It is widely supported in modern browsers.
Q: How much smaller will the file size be?
Depending on the image content, typically JPEG converts to about 70-80% of original size, and PNG to about 30-50%. Photos tend to compress more efficiently, while images with text or illustrations have lower compression rates.
Q: What is the quality after conversion?
Conversion at 80% quality maintains sufficient quality for web display while efficiently reducing file size. This is an optimized setting for general website use.
Q: What is the auto-resize feature?
This feature automatically resizes images over 1920px (Full HD) to 1920px. It's OFF by default and can be enabled as needed. This helps standardize images to optimal web display size while significantly reducing file size.
Q: When should I use auto-resize?
Recommended when preparing images for websites. Since Full HD (1920×1080) is the mainstream display resolution, higher resolutions are usually unnecessary. Keep it OFF for print use or when you need to preserve original resolution.
Q: Why is 1920px the standard?
Full HD (1920×1080) is the most common display resolution currently, and even on high-resolution displays, 1920px provides sufficient display quality. Higher resolutions just increase loading time without practical benefits for browser display.
Q: How do I paste images from clipboard?
You can directly paste screenshots or images copied from other applications using Ctrl+V (Mac: ⌘+V). Due to browser security restrictions, clipboard images are treated as PNG format.
Q: Where are converted images saved?
All processing is done in your browser and nothing is sent to any server. Converted images are downloaded directly to your device.
