Online utilities
These three tools do not convert photos or PDFs. They encode a file as Base64, tidy JSON, or generate UUID values. If you have an image and want Base64, there is also a dedicated image-to-Base64 tool.
Data and development
Base64 encodes the file you upload. The JSON formatter expects JSON text. The UUID generator creates IDs on the page and does not require an upload.
Frequently asked questions
Does Base64 turn a photo into PNG?
No. It encodes the file as Base64 text. Use an image converter to change the picture format.
Does the UUID generator store anything on the server?
It creates identifiers in the page. It is not a file converter like JPG to PNG.
Do these utilities replace image or PDF tools?
No. Use them when the job is data, not a photo or document format.
