Choose your conversion workflow

Start with a dedicated workspace for text payloads or image payloads. Both workflows are optimized for quick input, clear output, and direct actions.

How to use

  1. Choose Text or Image workflow.
  2. Paste content or upload a file based on your scenario.
  3. Copy the generated result or download decoded output.

Common Base64 Errors

Invalid characters in Base64

Base64 should only contain valid character sets and optional padding. Unexpected characters usually indicate a copied or corrupted value.

Missing padding

Some inputs miss trailing '=' padding. Depending on source format, decoding may fail or produce broken output.

Incorrect Data URL prefix

A malformed prefix such as data:image/...;base64 can break type detection and preview rendering.

Using the wrong conversion mode

Text payloads and image payloads should use different workspaces. Pick the mode that matches your input type.

Does this tool send data to a server?

In the current implementation, Base64 conversion logic runs in your browser during normal usage and does not require a dedicated conversion API.

Baidu Tongji script is enabled for aggregated visit statistics. Base64 conversion itself still runs locally in your browser.

Frequently Asked Questions

Can this tool handle both text and images?

Yes. The tool provides dedicated workflows for text payloads and image payloads.

Do I need the Data URL prefix for image decoding?

No. Data URL is supported, but raw Base64 is also accepted when it is valid image content.

Why do I see an invalid Base64 error?

Invalid characters, missing padding, or partially copied data are common causes.

Can I download decoded images?

Yes. In Base64 → Image mode, successful decoding provides image preview and download.

Is conversion done locally?

In the current implementation, conversion runs in the browser during normal usage.

Will this support more formats later?

Yes, the project structure is designed for incremental feature expansion.
