What can the image format converter change?

It changes only the file type between JPG, PNG, and WebP while keeping the source width and height.

Does the image format converter create new detail?

No. It re-encodes existing pixels without enhancement. Use Image to 4K when clarity or resolution needs improvement.

Does the image format converter keep local files private?

Yes. Local source files are processed in the browser. A pasted link is checked temporarily, and only a completed result is stored privately for up to 24 hours.

When does the image format converter show the price?

The exact price appears before conversion, and credits settle only after the private result is saved.
