Best Translation Apps for Mac: Choose by How You Work

There is no single best translation app for every Mac user. Some tools are made for an occasional sentence, others combine dictionaries with several translation services, and some can recognize text that you cannot select on screen.

Start with the work in front of you: Are you translating a highlighted passage, checking a word, reading text inside an image, or preparing a draft you will keep editing? This guide compares five options by workflow. Language coverage, integrations, and terms can change, so check each product's current documentation before choosing.

Compare the workflows and requirements

This is a workflow comparison, not a translation-quality ranking. Language support, service access, and terms can change; check the linked product documentation before installing or configuring a provider.

For occasional translation, try macOS first

macOS includes translation actions for supported text in some apps. While writing, you can also replace selected text with its translation. Live Text can recognize text in supported images, including images opened in Preview; a saved screenshot can therefore be opened in Preview and translated there. Some language resources are available for offline use. Availability depends on the macOS release, language, and content. Apple's Mac translation guide and Preview Live Text guide explain these workflows.

If you only need to understand or replace selected text, the built-in option may be enough. A dedicated app becomes more useful when you want a shortcut across apps, dictionary lookup, more service choices, or a direct screen-capture workflow without first saving an image and opening it in Preview.

If you prefer a translation service, evaluate its Mac workflow

If you want DeepL's translation workflow on Mac, its official Mac app page lists desktop shortcuts and current system requirements. It currently specifies macOS 14 or later and notes that saving translations for later is a DeepL Pro feature. Check its current language coverage and plan terms, then try representative text from your own work. Translation results vary by language pair and content, so broad claims about which service is “most accurate” are not a substitute for trying your own material.

For reading websites, browser translation or a bilingual web reader may be a better fit. Those tools focus on web pages and may not help with text inside desktop apps or screenshots.

For shortcuts, OCR, and multiple services, compare Bob and Easydict

Bob offers workflows for typed input, selected text, screenshot translation, and OCR-related tasks, along with multiple translation services and extensions. Easydict combines dictionary lookup with input and selection translation, screenshot OCR, and service options. Both are worth considering if you want translation available across Mac apps. Their current setup and feature details are documented in the Bob user guide and the Easydict project.

If vocabulary, pronunciation, and dictionary entries are central to your work, weigh those features more heavily than screenshot support. If you often translate app interfaces or images, look at how the OCR text is presented, whether you can correct it, and what permissions the workflow needs.

If you need to work with the text after translation, look at Frset

Frset has three translation entry points: type or paste text, translate a readable selection in another app, or select a screen area for text recognition and translation. Screen text is recognized locally on the Mac; you can then choose Apple system translation, Google, Microsoft, or a configured AI provider.

Input translation stays in the search tool: the source remains there and the translation appears in its preview. Successful input translations are saved in history. Selection and screen translation open a separate panel with source text and translation; you can edit the source, translate it again, and copy the result. That workflow may suit you if screen text often becomes something you need to copy or organize.

Frset is not a CAT tool for professional translators and does not provide a bilingual web-reading view. Selection translation requires macOS Accessibility permission and a source app that exposes readable, copyable text. Screen translation requires Screen Recording permission. Google, Microsoft, and remote AI providers receive the text you submit to them; local OCR does not make the full translation workflow offline. Its Apple system translation option requires macOS 15 or later and supported language resources.

Four things to check before choosing

1. Where does the text come from? A selectable passage, a draft in an input field, or text embedded in an image each calls for a different workflow.
2. What do you need from the result? A quick gist, dictionary details, editable source text, copying, or a saved record?
3. Does your language pair work? Support varies by operating system and service. Check target languages and offline requirements.
4. Where is the content processed? Local OCR and online translation are separate steps. Review the selected service's privacy terms before sending sensitive text.

Choose for the work you do most

For occasional selected text, start with macOS. If you prefer a particular translation service, evaluate its Mac app or web workflow. If you want dictionaries, screenshot OCR, or several services, compare Bob and Easydict. If you regularly translate screen content and then copy or organize the result, consider Frset.
