Frequently Asked Questions

Does it support raw Base64 without data:image prefix?

Yes. If you paste a raw Base64 string without the prefix, our engine automatically detects PNG, JPEG, GIF, WEBP, or SVG magic bytes and prepends the correct MIME header.

Is my decoded image uploaded to any server?

No. The image is rendered locally on your device using a client-side Data URL or Blob URL. Your files remain 100% private and confidential.
