Toolbox is a free collection of online tools for people who run websites and ad campaigns. Every tool works the moment you open it: nothing to install, no account to create, no usage limits.
Four of the five tools run entirely in your browser. The passwords you generate, the names you type in, the text you paste - all of it is processed on your own machine and stored in your browser localStorage. No step sends it to a server, nothing is logged, and nobody else can read it.
The one tool that needs a server is Pixel Mirror, because it has to open the source website and download its assets for you - something browsers do not let a web page do against another domain.
Toolbox is available in Vietnamese and English, has a light and a dark theme, and works on phones. Press Ctrl + K on any page to jump straight to the tool you need.
Why use Toolbox
Free, no sign-up
No paid tier, no usage cap, and no account to create before you can try anything.
Your data stays on your machine
Apart from Pixel Mirror, every tool runs in the browser and stores its state in localStorage - no server ever sees what you type.
No ads, no tracking
No banners, no popups, and no third-party behavioural tracking scripts.
Bilingual, with a dark theme
Switch between Vietnamese and English in one click; light or dark following your system setting.

Click a tool card on the home page, or press Ctrl + K and search by name.

Each tool is a single form, and results appear as you type or as soon as you press the button.
Copy or download the result
Every result field has a one-click copy button; Pixel Mirror hands back a zip file instead.
Frequently asked questions
Is Toolbox free?
Yes. Every tool is completely free, with no paid tier, no usage limit and no payment details required.
Do I need an account?
No. There is no sign-up and no login - open the page and start using it.
Is what I type sent to a server?
No, with one exception. Generator, Random Picker, Change WordPress Host and Content Breaking run entirely as JavaScript in your browser and keep their state in your own localStorage. Pixel Mirror has to send the URL to the server, because the server is what fetches the source site.
Does Toolbox work on mobile?
Yes. The layout adapts to the screen and every tool works in a mobile browser. Pixel Mirror returns a zip file, so a desktop is more convenient for that one.
Which tools are included?
Five: Generator (passwords, API keys, UUIDs), Random Picker (names and numbers), Change WordPress Host (generates the migration SQL), Content Breaking (Unicode lookalike text) and Pixel Mirror (downloads a site as static HTML).
Do the tools work offline?
Once the page has loaded, the four browser-side tools keep working without a connection. Pixel Mirror does not, since it depends on the server.
All tools
The five tools currently on Toolbox:
Content Breaking
Convert text into Unicode characters that look almost identical to ordinary letters, for captions, bios and headings. Converts as you type, one-click copy, free.
Pixel Mirror
Enter a URL, pick the pages you want and download static HTML, CSS and JS that runs offline. Two modes: Full uses a real browser, Lite is HTTP only.
Image to SVG
Convert PNG, JPG and WebP into SVG vectors in your browser. Tune colours and smoothing with a live preview. Your image is never uploaded.
Random Picker
Draw a random name from your own list or a random number from any range, with an optional no-repeat mode. Your list is stored in the browser. Free, no sign-up.
Change WordPress Host
Enter the old and new domain and get the SQL that updates wp_options, wp_posts and wp_postmeta. For moving WordPress to a new domain or from localhost to hosting.
Generator
Generate strong passwords, API keys, PINs, hex strings, Base64 keys and UUID v4 in your browser. Live entropy strength meter, nothing sent to a server.
