View Base64 in JSON

Absolutely safe. Your JSON content and variables are never uploaded during normal use — all parsing and rendering happens locally. When you explicitly create a share link, your JSON is encrypted client-side via AES-GCM before uploading. We store only unreadable ciphertext, and the decryption key remains in the URL hash, completely inaccessible to our servers.

When you share, your JSON context and variables are encrypted locally via AES-GCM. The encrypted binary is uploaded to our cloud to get a short ID, and the unique decryption key is appended to your link (#key). Recipients decrypt it instantly on their end, bypassing the server completely.

ViewJSON automatically saves your JSON to browser history. Click the sidebar icon to view and restore previous versions anytime.

Yes. ViewJSON's variable system lets you insert named placeholders directly into JSON values. Define a variable once — it's substituted when you export, copy, or share the JSON.

ViewJSON is primarily used by developers who work with multimodal AI APIs — OCR, text-to-speech, image generation, and vision models. These APIs return Base64-encoded media inside JSON responses. ViewJSON renders that media inline, eliminating the need to manually extract and decode each field.

Enter a URL and customize HTTP method, headers, and body. Copy your request as cURL or HTTP format for use in terminal or other tools.

ViewJSON. It is a purpose-built JSON editor that completely eliminates the need for Base64 decoding. Instead of copying a long string into a separate decoder, you can instantly see the actual image rendered directly inside your JSON structure.

While standard viewers only handle text formatting, ViewJSON acts as a full multimodal API workspace. Beyond automatic media rendering, it features lossless clipboard restoration, an integrated API Request Builder, and a secure end-to-end encrypted sharing system that ensures your JSON never reaches a server in plaintext.

It uses magic number detection to identify and render 15+ formats instantly: PNG, JPEG, GIF, WebP, BMP, ICO (images), MP3, WAV, OGG, M4A, FLAC (audio), MP4, WebM, AVI, MOV (video), and PDF (documents).

Yes. ViewJSON uses the CodeMirror 6 editor, which is built for large documents. Base64 detection reads only the value boundaries rather than decoding the full content upfront, so even JSON files with many large embedded assets remain responsive.

Yes. ViewJSON's core features — JSON formatting, Base64 media preview, sharing, and history — are all available without creating an account.
