Frequently Asked Questions
Is Base64 encoding with PDFPilot really free?
Yes. Base64 Encode is completely free to use, with no sign-up or account required.
Are my files uploaded to a server?
No. The encoding runs entirely in your browser using the browser's own FileReader API. Your file is never uploaded to PDFPilot's servers.
What file types can I encode?
Any file type — images, PDFs, spreadsheets, or any other binary file, since Base64 encoding operates on raw bytes, not a specific format.
Why would I need to Base64 encode a file?
Common uses include embedding a small image directly in CSS or HTML (data URIs), or including binary data in a JSON payload or configuration file, since both formats only support text.
Does Base64 encoding compress the file?
No — Base64 actually makes the data about 33% larger, since it's re-representing binary bytes as text characters, not compressing anything.
