Tool-specific questions
Can it decode ordinary text?
This page expects image bytes; use Base64 Text Encoder for text.
Is whitespace allowed?
Incidental whitespace may be ignored, but corrupted characters will fail.
Before you process
Can I use this base64 to image online without uploading my input?
Yes. This tool is labelled On-device, so the selected input is processed in your browser and is not sent to a ForgeMyFile processing API.
What happens if the browser cannot process it?
The tool shows a readable error and stops. It does not silently fall back to a cloud upload.
Why can performance differ between devices?
The browser is doing the work locally, so speed and practical file size depend on available memory, CPU and browser capabilities.
