FAQ

Does Base64 encoding increase file size?

Yes, Base64 encoding is about 33% larger than the original file. Recommend using AI compression to optimize images first, which can reduce size by 50-80%, offsetting encoding bloat.

How large of image files are supported?

Single file supports up to 50MB, recommend using compression for large files. Batch conversion total size limit is 200MB, suggest processing in batches if exceeded.

Will converted image quality be affected?

Base64 encoding is lossless conversion, not changing image quality. But AI compression is lossy optimization, you can choose compression level (low/medium/high) to control quality.

What is Data URI format?

Data URI format is data:image/png;base64,xxxxx, directly embeddable in HTML img tag src attribute or CSS background-image, reducing HTTP requests.

Can I save conversion results locally?

Yes. Can copy Base64 text to clipboard or download as .txt file. For reverse conversion, can directly download as original image format.
