Frequently asked questions

Are my files uploaded when I use Base32 Encoder / Decoder?

No. Base32 Encoder / Decoder runs entirely inside your browser. Your text is read locally, processed on your own device, and handed straight back to you. You can confirm this yourself: open your browser's developer tools, watch the Network tab, and run the tool — no request carries your data anywhere.

Is Base32 Encoder / Decoder free?

Yes, completely. No account, no sign-up, no watermark on your output, and no cap on how many times you can use it. The project is open source under the AGPL licence.

Does Base32 Encoder / Decoder work offline?

Mostly. The site caches itself after your first visit, so it keeps working without a connection. Tools that need a specialised library — PDF editing, OCR, QR codes, MP3 encoding — need a connection the first time you run them, then that library is cached too.
