Is the batch image to base64 converter private?
Yes. Each image is processed independently in the browser so one mismatched file does not replace the other results. All processing happens locally in your browser — nothing is uploaded to our servers.

Built for multiple images
Each image is processed independently in the browser so one mismatched file does not replace the other results.
No registration, watermark, queue, or server upload is required.
Use Base64 wisely
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.
Frequently asked questions
How many images can I convert at once?
There is no fixed count limit, but each file must be under 100 MB and total memory depends on your browser and device.
Does one failed file stop the batch?
No. Each image is processed independently, so valid files still produce results even if one file fails.
When should I use Base64 for multiple images?
Use it when a text-only channel or API must carry binary data, or when a small multiple images asset needs to live inside a self-contained document. Prefer separate files for large, cacheable public assets.
