Conversion changes the container and encoding; it does not recover detail lost in the source. A JPEG converted to PNG still contains JPEG-derived pixels and can become larger.
PNG suits lossless graphics and transparency, JPEG offers broad photographic compatibility, and WebP can provide efficient web delivery. Conversion runs locally on this device.
How to convert an image intentionally

Useful format-conversion jobs
Transparent web graphics
Convert an eligible source to PNG or WebP while retaining alpha.
Photo compatibility
Create a JPEG copy for a workflow that does not accept newer formats.
Web delivery
Create a WebP derivative for a supported website pipeline.
Conversion cannot restore source quality
- JPEG output cannot contain transparency.
- Converting a lossy source to PNG does not restore lost detail.
- Animated images are treated as a still image unless animation support is explicitly shown.
Image format questions
Will PNG make my JPEG clearer?
No. It avoids another lossy PNG encoding but cannot undo JPEG compression already present.
What happens to transparency in JPEG?
It must be replaced with an opaque background because JPEG has no alpha channel.
Are images uploaded?
No. Format conversion runs locally in this browser.
