Frequently Asked Questions
What is the difference between a Data URI and raw Base64?
A Data URI includes a metadata header specifying the MIME type and encoding (e.g., `data:image/jpeg;base64,`). Raw Base64 contains only the encoded characters. Our tool automatically detects and decodes both formats.
Will downloading as JPG preserve transparency?
No, the JPG specification does not support transparency. When downloading as JPG, transparent pixels are automatically filled with clean white. To preserve transparent backgrounds, download as PNG or WebP.
What image formats can be generated from decoded Base64 strings?
You can export your decoded Base64 string directly into PNG (best for logos and transparency), JPG (best for photographs and small file sizes), or WebP (modern next-gen format with superior compression).
Can I decode Base64 strings from JSON API responses and database dumps?
Yes, simply copy the base64 string from your REST API JSON payload, GraphQL query, or SQL database table (BLOB field) and paste it into the converter to view the rendered graphic instantly.
Is my Base64 encoded string transmitted to any external server?
No. All decoding and canvas rasterization take place 100% locally inside your web browser. Your private tokens, confidential documents, and sensitive medical/financial imagery encoded in Base64 remain strictly on your machine.
