HTTPS Upgrade Helper
Rewrite http:// links to https:// in pasted HTML or plain text. Runs entirely in your browser. Nothing is sent to Formsig.
About this tool
Paste HTML or plain text and rewrite http:// URLs to https://. Useful when migrating content or cleaning mixed-content links before publish.
Features
- Rewrites http:// to https:// in text and href/src-like patterns
- Optional skip for localhost and IP literals
- Shows count of replacements
- Copy upgraded output
Common use cases
- Cleaning CMS HTML after an SSL launch
- Fixing mixed-content warnings in pasted markup
- Upgrading links in email HTML templates
- Preparing docs that still cite http resources
How it works
A local replace walks http:// occurrences (case-insensitive) and upgrades them. It does not verify that HTTPS is available on the target host.
Privacy: this utility runs in your browser. Formsig serves the page but does not need your input to compute results.

FAQ
Will every upgraded URL work?
Not always. Some hosts still lack HTTPS. Spot-check important links after rewriting.
Does this change my live site?
No. It only transforms the text you paste here.
