7 tool sites plus 3 tools on this site, 56 distinct tools in all. How we count: a tool counts once whatever its languages, all QR code content types count once, and Kaomoji Garden's collections are not counted. The 5 languages are Traditional Chinese, English, Japanese, Korean and Simplified Chinese, and each site supports a different set.
The stage shows a single tool at a time. Every tool site is also written up in full further down.
The standards first
The 7 tool sites do different jobs, but they all follow the same four rules. Each rule comes with a source you can check.
Free, no sign-up
Every tool on this page works without an account. A few optional extras need a Google sign-in, and none of them blocks the main job.
Your data stays in your browser
Most tools for text, lists, addresses, photos and device tests do their work in your browser. Where a tool does send something, its page says so.
Official data, with sources
Taiwan ZIP codes and addresses come from Chunghwa Post. Overtime and severance results are tested against Taiwan's Ministry of Labor calculators. Emoji follow Unicode and CLDR. Passport photo sizes cite government pages.
Kept up to date
Each release is logged with its date and version. Articles show their date, plus an updated date when the content changes. When a tool cannot do something, it says so.
Every tool site, in full
Each one has a real screenshot, three steps to get started, its main features and a related guide. English interfaces come first, then the tools in Chinese, each labelled. It is all on this page, with nothing to expand.
Part 1 · 3 tool sites
For copying emoji and symbols, fixing photos, and checking a mouse, keyboard, speakers, mic or webcam. These sites have full English interfaces.
Kaomoji, emoji, special symbols and combos, sorted so you can find one fast and copy it with a tap.
Main features
1,795 kaomoji sit in 29 categories by mood and theme, next to 641 special symbols, 565 symbol combos and 1,906 emoji with names from Unicode CLDR. 168 emoji combos come with their meaning and when to use them. Favourites stay in your browser, and a Google sign-in is needed only for emoji combo extras such as submitting your own.
How to use it
ID copies, phone photos, quick edits and screen recordings, processed in your browser by default.
Main features
Watermark an ID copy before you send it, convert iPhone HEIC photos or WebP images to JPG, cover faces and number plates, edit with layers in the Photo Editor, or record your screen. Photos and recordings are not uploaded by default; the Photo Editor uploads a project only if you sign in with Google and save it to the cloud. The passport photo size chart covers the U.S., U.K., Canada, Australia and Taiwan, with official sources.
How to use it
Shows the mouse, keyboard, sound, mic and webcam signals your browser receives or plays, without pretending to diagnose hardware.
Main features
See the gap between clicks, clicks per second, and the key and code of every press. Play the left and right channels or a frequency sweep, watch your mic level and play back a short clip, and preview your webcam at the resolution the browser really gets. The mic and webcam ask for permission only after you press Start, and the sound and picture are not uploaded. The sound test only plays sound and is not a hearing test.
How to use it
Part 2 · 2 tool sites
The pages are in Chinese, but the jobs are short: type a link or an address, and get a code or an English address back. Each has an English guide on this site.
Make QR codes and barcodes, and read codes from images. The interface is in Chinese, but the steps are simple.
Make a code for a URL, WiFi network, contact card, text, email, phone number or SMS, and adjust the colours, gradient, logo and error correction. Codes are made in your browser with no watermark. Static QR codes do not expire, and you can use them commercially and in print.
How to use it
Look up 3-digit and 3+3 ZIP codes from Chunghwa Post data, and turn a Taiwan address into English. The interface is in Chinese.
Main features
The data is Chunghwa Post's 3+3 ZIP code release of April 27, 2026: 80,134 address ranges and 12,953 3+3 codes. Each of Taiwan's 22 cities and counties and 368 townships and districts has its own page. The address translator uses Chunghwa Post's English names for 30,030 roads and streets.

How the tools are made
Free, ready to use and respectful of your privacy. Tools say where their data comes from, what they assume and what they cannot do. Text, lists, addresses, photos and test data stay in your browser whenever they can.
The English pages are written for English readers with AI tools, following the editorial policy. Where an English page and its Chinese version disagree, the Chinese page is the reference.
