Repair missing padding, remove whitespace, extract Data URL payloads, and normalize Base64URL characters.
Normalization fixes common transport and copy-paste issues but cannot recreate bytes that were removed from the payload.
No registration, watermark, queue, or server upload is required.
Base64 is ideal for text-only APIs, small embedded assets, test fixtures, and portable documents. It increases payload size, so external files are usually better for large public assets.
Yes. Normalization fixes common transport and copy-paste issues but cannot recreate bytes that were removed from the payload. All processing happens locally in your browser — nothing is uploaded to our servers.
Missing padding, stray whitespace, URL-safe characters, and Data URL prefixes copied along with the payload.
No. If bytes were removed from the payload, the original data cannot be reconstructed — repair only normalizes formatting.
Use it when a text-only channel or API must carry binary data, or when a small malformed Base64 asset needs to live inside a self-contained document. Prefer separate files for large, cacheable public assets.
