Is the jpg to base64 converter private?
Yes. The encoder does not recompress JPEG data, so image quality and metadata remain unchanged. All processing happens locally in your browser — nothing is uploaded to our servers.

Built for JPG photos
The encoder does not recompress JPEG data, so image quality and metadata remain unchanged.
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
Will JPEG quality change during encoding?
No. The encoder reads the file bytes as-is and does not recompress the image, so quality and EXIF metadata remain unchanged.
Can I generate a ready-to-paste Data URL for CSS?
Yes. Choose the Data URL or CSS output format to get a complete declaration you can paste into a stylesheet.
When should I use Base64 for JPG photos?
Use it when a text-only channel or API must carry binary data, or when a small JPG photos asset needs to live inside a self-contained document. Prefer separate files for large, cacheable public assets.
