Frequently Asked Questions

Base64 to Image conversion decodes text-encoded image data back into viewable image files. Base64 is commonly used to embed images in HTML, CSS, emails, and APIs as text strings that can be easily transmitted and stored.
Our converter supports Base64 strings for all image formats including PNG, JPG/JPEG, GIF, WebP, BMP, and SVG. It automatically detects the image type from the Base64 header or data URI prefix (data:image/png;base64,...).
No, our converter works with both complete data URIs (data:image/png;base64,iVBORw0K...) and plain Base64 strings. If you only have the Base64 data without the prefix, it will attempt to detect the image format automatically.
Absolutely! All Base64 decoding happens locally in your browser using JavaScript - your data never leaves your device. No uploads to servers, no data collection, no storage. Your Base64 strings and decoded images remain completely private and secure.
Currently, our converter processes one Base64 string at a time for optimal performance. However, conversion is instantaneous (milliseconds), so you can quickly process multiple Base64 strings in succession.
The output format depends on the original image type encoded in the Base64 string. Our converter preserves the original format (PNG, JPG, GIF, etc.) and creates a downloadable image file with the correct extension.
Our converter automatically validates Base64 strings and provides error messages for invalid data. Valid image Base64 strings should contain recognizable image file headers and properly formatted encoding without corruption.
Yes! Our converter immediately displays a preview of the decoded image, allowing you to verify the result before downloading the file to your device.
