Is it really free?
Yes. All converters, compressors, and developer utilities are free with no registration required.
What happens to my uploaded files?
Files are stored in a temporary private folder and automatically deleted after 60 minutes. Download links stop working once the files are purged.
Is there a file size limit?
The default limit is 50 MB per file (configurable by the site administrator, and also bounded by the server upload limits).
Do the developer tools upload my data?
No. Code formatters, encoders, hash generators, and unit converters run 100% in your browser — nothing is sent to the server.
