What is Base64 Encoding?

Base64 is an encoding method that uses 64 printable characters to represent binary data.

Frequently Asked Questions

Will image quality be lost after Base64 conversion?

No. Base64 is just an encoding method. The conversion process does not compress or process the image. The image quality is identical to the original.

Is there a file size limit?

Theoretically no limit, but since processing is done in the browser, we recommend processing images under 10MB for the best experience.

Is the converted image data uploaded to the server?

No. All conversion operations are completed locally in your browser. We do not collect or upload any data, fully protecting your privacy and security.

Why can't my Base64 string be converted?

Please check the following: 1) Is the Base64 string complete? 2) Does it contain correct image data? 3) Are there extra spaces or line breaks in the string? We recommend copying the complete Base64 string directly.

Does it support batch conversion?

The current version does not support batch conversion. One image can be converted at a time. For multiple images, please convert them separately.
