Most free image converters ask you to upload your photo.
Your file travels to a server you can't see. You wait for it to go up and come back. And you have to trust that it gets deleted.
Browser-based tools skip the trip. Your browser converts the image on your own device.
What happens when you convert
Modern browsers can read, change and save images themselves. The conversion code downloads once with the page. After that, your image only ever exists on your device.
Upload tools vs browser tools
| Browser-based | Upload-based | |
|---|---|---|
| Where it runs | Your device | A remote server |
| Is your image sent? | No | Yes |
| Waiting for the upload | None | Depends on your connection |
| Big files | Depends on your device | Depends on the server |
Is it secure?
It removes one risk: your image is never sent to someone else's server. It does not make a site perfect, so check how any tool treats your files before using it for sensitive photos.
How to check for yourself
Open your browser's network tab, convert a photo, and look for an upload. With thedroppic you will not see one.
