Privacy, in plain words

Is it safe? Your image is not uploaded anywhere

What “uploaded” normally means. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website. That copy is what the word “upload” means, and it is the part nobody explains.

What happens instead. This site does not do it. There is no server here that receives files, so your image is read, converted and handed back by the browser you are using right now. It never travels — so there is no copy to store, read, leak or hand over.

Check it yourself in ten seconds

Turn off your Wi-Fi after this page has loaded, then convert a file anyway. It still works, because everything needed is already on your device.

The longer explanation of how this works, and the full detail of what is and is not stored on the privacy page.

Why this matters more than it sounds

Photographs carry more than what is in the frame — most also carry the time, the device and often the GPS coordinates where they were taken. It matters more than it sounds, because of what images usually are:

Medical scans and photographs

X-rays, results, images of a condition

Photographs of children

family pictures that should stay in the family

Passport and visa photos

biometric-grade images of your face

Screenshots of private messages

conversations that included other people

A file that is never sent cannot be kept, leaked, subpoenaed or used to train anything. That is a property of how this works, not a promise about how carefully it is run.

How Base64 to Image works

Decode a data URL or raw Base64 string back into a real image file. Everything happens inside this page: the file is read from your device into memory, processed there, and handed back as a download. It is never sent anywhere, and closing the tab discards it.

What it accepts: TXT. Files are identified by their contents rather than their name, so a mislabelled file is still handled correctly.
What happens to the data: Nothing is re-encoded. The content that comes out is identical to the content that went in, byte for byte, and running it twice changes nothing.
Size limit: Up to 40 MB per file. Because the work happens on your own machine, available memory is the real constraint — a laptop handles far more than a phone.

Base64 to Image — questions

How does Base64 to Image work?

Decode a data URL or raw Base64 string back into a real image file. Add your files above, adjust anything you want to change, and press the button. The result downloads straight to your device.

Is Base64 to Image safe — are my files uploaded to a server?

No, nothing is uploaded. On most online tools, pressing the button copies your file across the internet onto a computer owned by that website, where it is processed and then sent back. That copy is what "upload" means. This tool does not do it: your file is read and processed by the browser you are using right now, stays on this device the whole time, and is discarded when you close the tab. Turn off your Wi-Fi after the page loads and it still works, which is the quickest way to confirm it.

Can I use this on confidential or personal documents?

Yes — that is the case it was built for. Because the file never leaves your device, a confidential document is no more exposed than it is sitting in your own folder: there is no transfer, no copy on anybody else's hardware, no retention period and no staff with access. Nothing about the file is logged either — not its name, not its size, not its contents.
