Image Format Converter: How to use
Convert still images between JPG, PNG and WebP with explicit transparency handling.
- Choose one or more supported images.
- Choose PNG or WebP to retain transparency. Choose JPG with a background color for a flat, compatible output.
- Process, inspect the result and download.
Use case and output checks
Convert a transparent PNG to JPEG only after choosing a suitable background. JPEG cannot retain transparency, whereas supported PNG and WebP output can. Reopen the download on the target device and verify that the destination accepts the actual format, not merely a renamed extension.
Supported files and limits
JPG, PNG, WebP
Animated GIF and AVIF encoding are outside this version. A browser must support the chosen encoder; format fallback is never disguised.
Troubleshooting
No. This tool decodes and re-encodes pixels. Renaming .png to .jpg by itself changes the filename without changing the underlying image format.
