How it works
Choose a file or enter your data
Drop a file onto the upload area, pick one from your device or type your text and values.
Process it directly in your browser
Your device does the work. Nothing is sent to a server, so there is no upload to wait for.
Download or copy the result
Save the result individually or as a ZIP, or copy it to the clipboard with one click.
Why ToolHarbor?
A collection of honest, focused tools that do their job without collecting your data.
Your files stay on your device
- All tools run as JavaScript in your browser. Images, PDFs and text are never uploaded.
- Every library the tools need is hosted on this site. No third-party servers, CDNs or font services are contacted.
- No account, no cookies, no tracking and no ads.
- A security policy (CSP) additionally tells your browser to block connections to other servers.
Local browser processing
Images, PDFs and text are processed with JavaScript on your device. The site has no upload server.
No account required
Open a tool and use it straight away – no registration, no e-mail address, no login.
Fast downloads
Because nothing has to be uploaded or downloaded from a server, results are ready as soon as your device has finished.
Works on desktop and mobile
Every tool is designed for touch screens and small displays as well as for mouse and keyboard.
Transparent limitations
Each tool explains what it cannot do – for example when a PDF cannot be made smaller – instead of hiding it.
