How it works
Your utf-8 work stays on your device
All 69 utf-8 tools on this page are JavaScript that your browser downloads once and then runs on your own machine. No server sees your input, because no server is involved in the work at all.
Put the text you paste into any of these tools and it stays inside this tab.
How most online tools do it
Every character sent to a stranger's server- Text from an internal docin your clipboard
- Sent to their serverlogged, cached, who knows
- The result comes backafter a round trip
How EditSafely does it
0 bytes over the network- Text from an internal docin your clipboard
- Your browser does the workin this tab, in memory
- The transformed textappears as you type
There is no upload step
Your browser opens the file from your disk the same way an installed app would. The bytes go from your drive into this tab and no further.
Big files are not a problem
No server means no upload limit and no queue. Speed comes down to your own machine, so a multi gigabyte file starts processing right away instead of after a long transfer.
It keeps working offline
Once the page has loaded you can disconnect from the internet entirely and the tool carries on. There is nothing on the other end for it to talk to.
Nothing is stored anywhere
No account, no history, no copy on a server waiting to be leaked. Close the tab and the work is gone from everywhere it ever existed.
