Frequently Asked Questions
Answers to common questions about this tool.
Do I need to install anything to convert Image to Base64?
No. Image to Base64 runs entirely in your browser — there is nothing to download, no extension and no desktop program. It works the same on Windows, macOS, Linux, Android and iPhone.
Is it safe to convert Image to Base64 online?
Safer than the usual alternative, yes. Most online tools upload your file to a server you know nothing about, where it sits until someone deletes it. Here the file never leaves your device — the processing happens in the page itself, so there is no server copy to leak, retain or sell.
Does Image to Base64 reduce my photo’s quality?
Converting and cropping keep quality close to the original. Compressing trades a little detail for a much smaller file, and a lighter setting keeps more of it. Compare the preview with your original before saving.
Will my photo be accepted by the exam form?
The exam photo tools follow the size, dimensions and file weight given in the official notice. Always read the latest notice too, because boards sometimes change their rules between years.
Can I edit pictures with Image to Base64 straight from my gallery?
Yes. Pick a photo from your gallery or take one with the camera, then save the result back to your phone. Everything works in the browser, so there is no app to install.
Is Image to Base64 free with no watermark?
Yes. Use it for as many pictures as you need without an account, and each image comes back without any logo or mark from the site.
