Encoding Binary Files for API Payloads
Base64 enables seamless file transport across REST endpoints, GraphQL queries, and microservice architectures without requiring multipart form-data.
Frequently Asked Questions
Why should I convert binary files to Base64?
Converting files to Base64 allows you to serialize binary data into JSON payloads, embed files in database documents, or send attachments over text-based API webhooks.
Which file formats can I encode to Base64?
You can encode any file: ZIP archives, Word (.docx), Excel (.xlsx), PowerPoint (.pptx), PDF, binary files, and fonts.
Is there a file size limit for in-browser file encoding?
You can encode files up to 50MB quickly without upload timeouts since conversion executes in your browser's local memory.
Are my confidential files uploaded or saved on a server?
No, 100% private. Your files never leave your computer.
How do I encode a file to Base64 in Python?
In Python, use: 'import base64 with open("file.zip", "rb") as f: encoded = base64.b64encode(f.read()).decode()'.
How much larger is a Base64 string compared to the original file?
Base64 increases the data size by approximately 33% (4 Base64 characters per 3 binary bytes).
