Frequently Asked Questions
Is my data safe when using this Base64 to PNG decoder?
Yes, absolutely. Image Studio executes all decoding operations directly in your browser using client-side technology. Your data is never uploaded to our servers, keeping your sensitive information completely secure, private, and offline-capable.
Does this tool support Base64 strings with "data:image/png;base64" prefixes?
Yes. Our smart decoder automatically detects and strips Data URI prefixes, chunked line breaks, and raw formatting, giving you a clean PNG preview without requiring any manual text editing.
Will my PNG's transparent background be preserved?
Yes. The decoder perfectly preserves the original transparency (alpha channels) of your PNG image, ensuring it renders and downloads exactly as it was originally encoded.
Are there any file size limits or usage restrictions?
No. Because the application runs entirely locally on your device, there are no artificial file size caps, rate limits, or daily conversion restrictions. You can decode as many files as you need, completely free.
