Frequently Asked Questions
Does this tool upload my data to a server?
No. All decoding and image processing is done entirely in your browser using JavaScript. Your Base64 data never leaves your device and is never sent to any server.
What Base64 formats are supported?
This tool accepts both raw Base64 strings and full data URI strings (e.g., data:image/png;base64,...). If you paste a raw Base64 string without a data URI prefix, the tool will attempt to auto-detect the image format.
What image formats can be decoded?
Any image format supported by your browser can be decoded, including PNG, JPEG, GIF, WebP, SVG, and BMP. The format is auto-detected from the data URI or from the image content itself.
Is there a size limit for the Base64 string?
There is no hard limit enforced by the tool. However, very large Base64 strings (representing images over 20MB) may cause your browser to slow down depending on your device's available memory.
What format will the downloaded image be in?
If you provide a data URI, the image is downloaded in its original format (PNG, JPEG, etc.). For raw Base64 input without a data URI prefix, the image is downloaded as PNG by default.
