What is Bulk Conversion?
Bulk Base64 conversion allows you to process multiple files simultaneously, saving time when you need to convert many files at once. Each file is independently converted to Base64, and you can download results individually or as a single JSON file.
Common Use Cases
Batch Image Processing: Convert multiple product images, thumbnails, or icons to Base64 for embedding in web applications.
API Development: Prepare multiple files for API testing or data migration by converting them to Base64 format.
Documentation: Embed multiple diagrams or screenshots directly into documentation by converting them to Base64.
Data Export: Export file collections from databases or CMS systems as Base64 for backup or transfer.
How to Use
Step 1: Click the file input and select multiple files (you can select many at once using Ctrl/Cmd + click).
Step 2: Click "Convert All to Base64" to process all files.
Step 3: Copy individual Base64 strings or download all results as a JSON file containing all conversions.
Performance Notes
Large files (over 10MB each) may take longer to process. For optimal performance, keep individual files under 5MB. Very large batches (100+ files) may cause browser slowdowns depending on your device's capabilities.
Privacy and Security
All file processing happens locally in your browser. Your files are never uploaded to any server. This ensures complete privacy for sensitive or confidential files.
