Frequently Asked Questions
1. Will converting to WebP reduce image quality?
Not noticeably. WebP supports both lossy and lossless compression. At 80-90% quality, WebP images are visually identical to JPEG but 25-35% smaller.
2. Can I convert a PNG with a transparent background?
Yes. Converting to WebP preserves transparency. Converting to JPEG will fill transparent areas with a white background since JPEG doesn't support alpha channels.
3. Is there a limit on the number of files I can convert?
There's no hard limit. You can batch convert as many files as your browser's memory allows. For very large batches, we recommend groups of 20-30 images.
