FAQ
What is Base64 encoding?
Base64 encodes binary data as ASCII text, making it safe to embed in HTML, CSS, JSON, or send in emails.
What file types can I encode?
Any file type — images, PDFs, documents, audio, video, and more.
Is there a file size limit?
No hard limit, but very large files may be slow to encode in the browser. Files under 10MB work best.
Is my file uploaded to a server?
No. Encoding happens entirely in your browser.
