FAQ

Q1: Can I convert multiple images at once?

Yes! Select or drag multiple images (up to 20), convert them all with one click, and download as a ZIP file.

Q2: Which format should I choose?

Use JPG for photos without transparency (smallest size). Use PNG for graphics with transparency or when lossless quality is needed. Use WebP for modern web use with excellent compression.

Q3: Will I lose quality when converting?

Converting to JPG or WebP involves lossy compression, so some quality may be lost. Converting to PNG is lossless but may increase file size. Use the quality slider to control the trade-off.

Q4: Are my images uploaded anywhere?

No. All conversion happens locally in your browser. Your images never leave your device, making this tool completely private and secure.

Q5: What's the advantage of WebP format?

WebP offers 25-35% smaller file sizes than JPG with similar quality, and supports transparency like PNG. Most modern browsers support WebP, making it ideal for web use.
