Encode text, decode Base64, or convert a local file to Base64 in your browser.
Tool introduction
Base64 is a way to represent binary data as plain text. Developers often see it in API payloads, data URLs, tokens, file previews, and email or upload workflows.
The ChlatWork Base64 tool supports text encoding, text decoding, and local file-to-Base64 conversion in one place.
Privacy and processing
Base64 increases size, so avoid using it for very large files when a normal upload is better.
Check whether your API needs raw Base64 or a data URL prefix.
Use UTF-8 text when encoding normal language content.
Do not treat Base64 as encryption; it is easy to decode.
Avoid sharing decoded values if they contain credentials or personal data.
No. Base64 is encoding, not encryption. Anyone can decode it.
Yes. Use the File to Base64 mode to choose a local file and generate text output.
Base64 text is usually larger than the binary data it represents.
Invalid input will show an error. Check for missing characters, extra spaces, or the wrong data format.
The tool is designed to read the chosen file locally in the browser.
Split group spending and calculate who pays who.
Batch compress images instantly without uploading to a conversion server.
Convert JPG, PNG, and WebP images into one clean PDF file instantly.
