Know your source format · JFIF
JFIF stores JPEG image data. Renaming a .jfif file does not turn it into PNG or WebP. This tool reads the image and encodes a new file in the selected format.
When to choose this output · WebP
WebP can be useful for web images and supports transparency. This tool uses lossy WebP encoding; a smaller file is not guaranteed. If your browser cannot encode WebP, an error appears instead of a mislabeled file.
Frequently asked questions
Are my files uploaded or overwritten?
Images are processed in your browser. Originals stay unchanged and results download as new files. Pixels are re-encoded; this is not a tool for preserving original metadata.
