FORMAT & FEATURE GUIDE
Which dictionary format should I choose?
The engine provides 54 import formats and 46 export formats. These common formats have specific tested samples; compatibility still depends on the file contents and conversion direction.
| Dictionary format | File type | Import code | Export code | Usage notes |
|---|---|---|---|---|
| Sogou SCEL | .scel | scel | scel | Sogou cell dictionaries. Convert to Rime or plain text; original word frequencies may not be fully preserved. |
| Rime | .dict.yaml | rime | rime | Exports TSV entries without a YAML metadata header. Add metadata before importing into Rime. Entries are always sorted by descending frequency. |
| Gboard text | TXT | gboard | gboard | Extract your Gboard backup, then select its text dictionary. ZIP files cannot be imported directly. |
| Gboard binary | user_dict_3_3 | gboardbin | gboardbin | Gboard binary and text dictionaries use different formats. Choose the format that matches the file contents. |
| QQ Pinyin | .qpyd | qpyd | — | QPYD import is supported. To export a QQ dictionary, choose the corresponding available export format in the full catalog. |
| Plain word list TXT | .txt | word | word | One word per line. Enable Pinyin or another code generator in advanced settings when the output format requires codes. |
Make the dictionary yours
Generate Pinyin, Wubi, and other codes. Convert Chinese scripts, filter by length and frequency, remove characters, or change sorting and frequency. Defaults preserve the source settings without automatic deduplication.
From browser to keyboard
Check the preview and messages before importing into your target input method. On iPhone, try DDUP, a keyboard that supports Sogou and text dictionary imports.

A LITTLE HELP
Before you convert
How do I convert a dictionary?
Choose one or more files in the same format, select the input and output formats, then choose “Convert dictionary”. For TXT with one word per line, select “Word list” and enable Pinyin generation when the target format requires codes.
Are my files uploaded?
No. WebAssembly converts files locally in your browser. Network requests only load the website and engine assets; dictionary contents are never sent to a server. Save your downloads before closing the page.
Why are there no exported entries?
Check that the selected input format matches the file contents. Plain TXT has no Pinyin, so formats such as Rime may need code generation. Restrictive filters can also remove all entries. Some formats remain unverified; check the result messages.
What compatibility limits should I know about?
Big5 input has an upstream decoding issue. Extract Gboard ZIP backups and choose the correct text or binary format. Rime output has no YAML metadata header. Formats such as SCEL may not preserve all original frequencies. Review your results.
Can I convert large dictionaries on my phone?
Small dictionaries can be processed in a mobile browser. Large files use more memory; above 10 MB, use smaller batches or a computer. The combined input limit is 50 MB, and completion depends on your device.
