Are online image tools safe? How to check yours
Quick answer
An online image tool is only as private as the place it does its work. Many send your photo to a server; iDuckImg does the work in your browser, so the file stays on your device. You can check this yourself in the browser Network tab.
Steps
- Open the tool page, then open your browser developer tools (F12) and choose the Network tab.
- Clear the list, then drop a picture into the tool and run it.
- Look for large requests that carry your picture, usually shown as POST or PUT. A tool that works on your device shows none.
- Read the privacy policy of any tool you use, and check what it says it keeps and for how long.
Why it matters
A photo can contain faces, documents, a house number and hidden details such as the exact place it was taken. Uploading it hands a copy to someone else, and you cannot see what happens next.
Tools that work in your browser avoid that, because your file is processed by your own device and is never sent. They also tend to be faster, since there is no upload or download.
What iDuckImg does
Every iDuckImg tool runs in your browser. Your pictures are not uploaded, there is no sign-up and no watermark is added. The page loads its own code and files from the same site, and for some formats such as HEIC a decoder from the same site. It makes no requests to other companies.
Still worth doing: remove hidden location data before you share a photo, and use Cover rather than a light blur to hide anything private. The Remove EXIF data and Blur or hide tools do those jobs on your device.
Common questions
How can I tell if a tool uploads my photo?
Open the Network tab in your browser developer tools, run the tool and look for a large request that carries your picture. If there is none, the work happened on your device.
Does iDuckImg upload my pictures?
No. Each tool runs in your browser and your files stay on your device.
Is it safe to share a photo after editing it?
Remove the hidden location and camera data first, and hide anything private in the picture itself with a solid cover.
