Frequently asked
Is my image uploaded to a server?
No. Image to Base64 Converter runs entirely in your browser using standard browser APIs. Your image never leaves your device and we don’t store anything.
Which formats are supported?
JPG, PNG, WebP, GIF, BMP and any other format your browser can open. Output is PNG, JPG or WebP depending on the tool.
Is there a file size limit?
We don’t impose one. Because everything runs on your device, extremely large images depend on your browser’s available memory — anything a phone camera produces is fine.
Is Image to Base64 free? Do I need an account?
Yes, it is completely free and there is no account, sign-up or watermark. It is one of 78 free browser tools from ModelsGroup.
Does it work on my phone?
Yes. It works in Safari and Chrome on iPhone, iPad and Android — you can even add photos straight from your camera roll.
