Using Base64 encoding for image uploads on the client side and sending it to the server can work, but there are several important security, performance, and reliability implications to consider:
- Increased Payload Size: Base64 encoding increases the size of the image by approximately 33%. This means that your upload size will be larger than the original image file, resulting in slower uploads and more bandwidth usage.
- Client-Side Processing: Encoding an image to Base64 on the client side can be computationally expensive for large images, potentially affecting the performance of your app, especially on mobile devices or low-powered clients.
- Lack of File Integrity Checks: Base64 does not inherently provide any mechanisms for verifying the integrity of the file. If the encoding process or transmission is corrupted, the image might be unusable on the server side.
- Cross-Site Scripting (XSS) Risks: If not properly
