Convert Base64 to Image Online (Decoder)
Developers often store images as Base64 strings in databases or JSON files. However, viewing these images is difficult because they are just long strings of text. InstantConvert.online offers a smart Base64 to Image Decoder that converts these strings back into viewable files (PNG, JPG, GIF, WebP).
Why is our Decoder "Smart"?
Base64 strings are fragile. If you copy them from a terminal, they often contain "garbage" characters like newlines or spaces that break standard decoders.
