Frequently Asked Questions
Why should I convert my JPG and PNG images to WebP?
WebP is a highly optimized next-gen image format recommended by Google. It provides superior lossless and lossy compression, rendering pages up to 3x faster.
Can I perform offline image conversions without internet?
Yes, once Checkistan is fully loaded in your browser tab, the Image Converter operates fully offline without any network traffic.
Are transparent PNG backdrops preserved during conversion?
If you convert transparent PNGs to WebP, alpha transparency is preserved perfectly. Converting to JPEG will automatically blend transparent areas with a solid white background.
