Frequently Asked Questions
Does converting to JPG reduce image quality?▼
JPG uses lossy compression, so a small amount of detail is discarded to shrink file size. At high quality settings the difference is invisible to the eye, and ChameLeo converts at a level that keeps your images looking sharp.
Can a JPG file have a transparent background?▼
No. JPG does not support transparency — transparent areas are flattened onto a solid background. If you need transparency, convert to PNG or WebP instead.
When should I use JPG instead of PNG?▼
Use JPG for photos and complex images with many colors — it produces much smaller files than PNG for photographic content. Use PNG when you need transparency or pixel-perfect sharpness like logos and screenshots.
Why are my JPG files smaller than the original PNG?▼
JPG's lossy compression is optimized for photographs, typically cutting file size by 50–90% compared to PNG. That makes JPG ideal for sharing, email attachments, and web uploads.
Is it safe to convert private photos with this tool?▼
Yes. ChameLeo converts everything locally in your browser — your photos are never uploaded to any server. Once you close the tab, nothing remains.
