What it does
Translate anywhere Ctrl+Q
Select text in any application and read it translated, in place.
Replace as you go Ctrl+Shift+T
Swaps your selection for the translation, without a round trip.
Screen OCR Ctrl+I
Draw a box over anything on screen. Or drop an image in, or paste one from the clipboard.
Read it aloud Ctrl+E
Hear the pronunciation of the source or the translation.
Quick Dictionary Ctrl+D
Definitions for any word without leaving what you were reading. Translate a single word and the definition is simply there.
See the word Ctrl+Shift+Q
Reference pictures from Wikimedia Commons, for the words a definition does not settle. Diagrams, not stock photography.
Whole documents
DOCX, PDF, TXT, SRT and VTT, translated with their formatting intact.
Summarize & rewrite
Shorten a passage, or recast it formal, casual or simplified.
Backward translation
Translate the result back to spot phrasing that has drifted.
Spell checking
Live suggestions as you type, before you translate.
Translation rules
Pick the target language automatically from the language detected.
History you can search
Every translation kept, browsable, and restorable in a click.
Right-to-left, properly
The whole window mirrors for Arabic, Hebrew and Farsi — not just the text.
Three layouts, 30+ themes
Classic, side-by-side or compact. Themes follow your system light and dark, and five icon sets change how the whole interface is drawn.
Every key rebindable
Nothing is hard-wired, and shortcuts can be global or app-only.
Private, local AI
Point it at Ollama or LM Studio and nothing leaves your machine. No account, no API key, no per-word cost. For anything under an NDA.
Your network, your rules
An HTTP proxy with credentials, timeouts you set yourself, and a cap on how much any one service may open. In one place, not once per plugin.
Translate the app itself
A built-in editor lists every string with its English beside yours, shows what is still missing, and can draft a suggestion for you to correct. Translators are credited by name.
Plugins
QTranslate uses a plugin system — translation engines, OCR, TTS, and
spell checkers are all separate .jar files installed at
runtime. When a service breaks or changes its API, you swap the plugin
without reinstalling the app.
Ten are bundled, and every one of them works out of the box:
| Plugin | Provides | Setup |
|---|---|---|
| TranslateOCRSpeechSpellingDictionary | None | |
| AI Services | TranslateSummarizeRewriteSpellingDictionaryVision OCR | API key — 300+ models via OpenRouter |
| Bing | TranslateSpeechSpelling | None |
| DeepL | Translate | Optional key — free tier works without one |
| LibreTranslate | Translate | Self-hosted — nothing leaves your machine |
| Mozhi | Translate | None — tests public instances, picks the fastest |
| MyMemory | Translate | None |
| Reverso | Translate | None |
| Yandex | Translate | None |
| Wikimedia | DictionaryImages | None — Wikipedia, Wiktionary and Commons via the MediaWiki API |
| CSV Dictionary | Dictionary | None — reads a file you choose; nothing leaves your machine |
You can build your own plugin — a minimal translator is about 50 lines of Kotlin.

Installation
Windows
- Download the Windows build above and unzip it anywhere.
-
Run
QTranslate.exe. Nothing else to install — the Java runtime is inside.
macOS & Linux
- Install Java 11 or later if you do not have it — Adoptium is the usual source.
- Download the portable zip above and unzip it anywhere.
-
Run
QTranslate.jar, or from a terminal:java -jar QTranslate.jar
The app starts in the system tray. The portable zip carries every bundled plugin, the language files and the themes — nothing is written outside its own folder, so it travels on a USB stick.
Getting "this application requires a Java Runtime Environment"? This video walks through installing Java and setting JAVA_HOME — the first 7 minutes cover everything.
Releases
All new releases are published on GitHub Releases. Versioning restarts from 1.0.0 with the open-source release — the old versions below were pre-open-source and are kept here for reference only.
1.4.0 Latest Aug 18, 2026 Downloads →
- A translation editor. Translate the app itself without leaving it: every string with its English beside yours, a filter for what is missing, and a draft suggestion you can correct. Translators are credited by name, and Settings says how complete each language is
- Network settings. An HTTP proxy with credentials kept in the secret store, timeouts for the whole request and for each stage, a longer timeout for one particular service, configurable retries, and a cap on connections per service
-
Image search
Ctrl+Shift+Q. Reference pictures from Wikimedia Commons for the words a definition does not settle, filtered to diagrams or photographs - A short definition under single-word translations, in the popup and the main window, with no click and no toggle
- A local, private AI setup. Point AI Services at Ollama or LM Studio and nothing leaves your machine: no account, no API key, no per-word cost
- CSV Dictionary plugin. Look terms up in your own CSV: a glossary, an abbreviation list, error codes, study mnemonics
- Five icon sets. Lucide, Material Symbols, Phosphor, Tabler and Heroicons, or a folder of your own SVGs
- Search the settings. Find any setting by name, by its section, or by a word that appears only in its explanation
- Vietnamese, contributed by the community, plus improvements to Turkish, Hungarian and Italian
- Plugin API v2. What a service is for now follows from the interfaces it implements, settings are typed and scoped per plugin, credentials live in their own store, and plugins are handed an HTTP client by the app. Plugins built against v1 must be rebuilt; existing service selections convert automatically
- Settings reorganised into two groups rather than eight flat pages, and the Quick Translate popup can change languages and be driven entirely from the keyboard
- API keys moved out of the plugin settings file into a separate credential store
- Popup auto-hide raised from 3 seconds to 12, and definitions from 8 to 20, neither of which was long enough to read
- Plugins can ship their own translations, so plugin text is no longer English-only
- QTranslate now renders at the display's scale. On a 150% or 200% screen it had been drawing scaled icons around unscaled text and opening at half the size its contents needed
- The interface no longer grows by a further 25% on every theme or font change
- Translation requests are no longer sent twice when a service fails mid-request, which could mean paying twice for one attempt
- The Arabic interface lays out correctly, including the Settings dialog and the docked dictionary
- Choosing English as the interface language now survives a restart
- Unreadable settings are copied aside and reported instead of being silently replaced by defaults
- A translation containing an ordinary percent sign could take down the window that showed it
- Windows on a display left of or above the main one no longer fail when their position is saved, and a window saved on a monitor that is no longer attached comes back into view
1.3.0 Aug 14, 2026 Downloads →
- Document translation — drop in a DOCX, PDF, TXT, SRT, or VTT file and get it back translated with formatting intact
-
Windows package with bundled Java — extract

- Wikimedia Reference — Wikipedia and Wiktionary lookups via the official MediaWiki APIs
- Optional floating translate button next to selected text — off by default, under Settings → General
- Six new rebindable shortcuts: copy translation, clear input, swap languages, open settings, show history, translate document
- New QTranslate Light and QTranslate Dark themes built on the project's own palette, WCAG-checked
- Extra output panel loads on its own — translations no longer held back waiting for the slower of two requests
- Window opens immediately on startup instead of waiting for all plugins to initialise
- Instant translation debounce reduced from 700 ms to 350 ms
- Plugin manager rebuilt — search, filter, enable, configure, and install by file picker or drag-and-drop
- Every network service failed in the Windows package due to a missing elliptic-curve crypto provider — translation, dictionary and TTS all broken
- Global hotkeys now work on non-US keyboard layouts
- Quick Translate reads the original text aloud, not the translation
- Google translation now supports Croatian and Farsi
- Selected-text capture more reliable across applications
