Format a JSON blob, test a regex, or hash a string without leaving the browser tab you’re already in.
Writers & marketers
Check word counts, clean up spacing, and generate placeholder copy while drafting or reviewing.
Students
Shrink a PDF before a submission portal rejects it, or check the exact age or date interval for a form.
Freelancers & designers
Convert client images, pull a color from a mockup, or turn a JPG into a clean, shareable PDF.

Good to know
Is penpost really free?
Yes, every tool is free to use, with no premium plan, usage cap, or hidden charge behind any of them.
Do you store my data?
No. Tools run client-side in your browser, so text and files you enter are never uploaded or logged on our servers.
Can I suggest a new tool?
Always. If there’s a small, repetitive task you’re solving with three browser tabs and a spreadsheet, tell us. That’s exactly what penpost is for.
Do I need to sign up?
No account, no email, no login. Open a tool and start using it.
Can I use penpost on mobile?
Yes. Every tool works in any modern mobile browser, no app to install and nothing to keep updated.
Which browsers are supported?
The latest versions of Chrome, Firefox, Safari, and Edge. Since processing happens in your browser, an up-to-date browser gives the smoothest experience.
Can I use these tools for commercial work?
Yes. Results from any tool, whether it’s a converted file, a generated password, or formatted text, are yours to use however you like, including commercially.
How often are new tools added?
Regularly. The library grows based on what people actually ask for, so a suggestion today can become a tool sooner than you’d expect.
Pick a tool. It’s free forever.
