Papago (파파고) and Google Translate solve different problems. Papago covers 14 languages with text, voice, image, offline, and document modes built around Naver's own service. Google Translate's own App Store listing claims support for up to 249 languages, with camera translation and a real-time conversation mode called Live Translate. Naver Dictionary (네이버 사전), a separate Naver product easily confused with Papago, isn't a translator at all. It's a word-level dictionary. None of the three is safe to rely on alone for a contract, a lease, or a hospital visit.
Papago and Naver Dictionary are not the same app
Both come from Naver, and the confusion is understandable. But they have separate help centers, separate purposes, and separate strengths.
Naver Dictionary is what you want when you need one word: a definition, a pronunciation, or an example sentence. Its own help center organizes content into per-language dictionaries, a crowd-sourced open dictionary (오픈사전), and a bundled encyclopedia layer (지식백과) covering everyday and academic topics.
Two features make Naver Dictionary worth knowing about specifically:
- Japanese phonetic input. Naver's help page describes five ways to search the Japanese dictionary: typing Japanese directly, typing the Korean-phonetic spelling of a word, typing a romanized spelling, drawing the characters by hand with handwriting recognition, and typing through a Japanese input keyboard (IME). Type 아리가토 in Hangul and it finds ありがとう. Type "arigato" and it does the same. Useful if you know how a Japanese word sounds but can't type the characters.
- Hanja handwriting search. Naver's Chinese-character (Hanja) dictionary lets you draw a character or search by its shape, for cases where you don't know how to pronounce it. Naver's own help page confirms both a handwriting recognizer and a shape-component search exist for exactly this problem.
Papago, by contrast, is for translating a full sentence, a conversation, or a document. Use it when you have more than one word to translate.
Pick by what you're trying to do
You need to read a sign or a menu
Papago's image translation is an upload-based flow: drag or attach a photo, then wait for the result. Naver's own help page is specific about the limits: image translation requires you to be logged in, and it's capped at 30 translations per month, resetting on the first of each month Korea Standard Time. It accepts JPG, JPEG, GIF, and PNG files under 20MB, across the same 14 languages Papago supports for text.
Google Translate's camera translation works differently: you point your phone's camera at the text and it translates on the spot, without uploading anything. Google's own help documentation carries a caution worth remembering for both apps: translation accuracy depends on the clarity of the text, and small, unclear, or stylized text may not translate accurately. A handwritten note or a stylized restaurant sign is where camera translation is most likely to get something wrong.
You need to talk to someone right now
Papago has a named mode for this, conversation translation (대화 번역), separate from its single-direction voice translation. Naver's help page confirms conversation translation exists as its own feature, distinct from the basic voice mode.
Google's equivalent is called Live Translate. Google's help documentation describes automatic speaker-switch detection: the microphone detects when one language stops and the other starts, so two people can go back and forth without manually flipping a switch. Google also documents a "Listening" mode for headphones and a "Text only" mode as alternatives.
You need to look up one word
This is Naver Dictionary's job, not Papago's or Google Translate's. Both translation apps are built to translate strings of text, not to give you a dictionary-style breakdown of one word's meanings, part of speech, and usage examples.
You're about to be offline
Both Papago and Google Translate support offline translation, but read the fine print before you count on it.
Papago's own help page states plainly that offline mode only covers text. Once you're offline, voice translation, image translation, and conversation translation all stop working. If your plan involves talking to someone or reading a sign while offline, Papago won't help.
Google's offline mode works through a downloaded language pack. Once a language is downloaded, Google's help documentation says camera translation can work offline too, through that same downloaded language. Download the languages you'll need before you lose signal, not after.
You need to translate a document
Papago has a dedicated document translation mode (문서 번역), separate from image translation. Naver's own help page lists the specifics: it accepts PDF, HWPX, DOCX, PPTX, and XLSX files, requires login, and caps at 20,000 characters and 20MB per file. This is the mode to use for a multi-page PDF, not image translation, which is built for a single photo.
Papago's website translation is gone. Use Whale instead.
Older write-ups about Papago, including some still online, describe a standalone tool for translating entire websites inside Papago's own web app. That feature no longer exists.
Naver's own help page confirms it directly: the website-translation function that Papago Web used to offer has ended. Instead, Papago's translation engine is built into Naver's Whale browser (웨일 브라우저), and translating a website now means using Whale's built-in translation feature rather than a separate Papago tool. If you're looking for the old Papago website-translate option and can't find it, this is why. It moved into a different product.
Where machine translation gets you into trouble
Papago, Google Translate, and any camera-based OCR tool are good at what they're built for: a sign, a menu, a casual message, a quick word lookup. They're not built, and aren't documented by either company as reliable, for situations where getting the wording exactly right matters.
Formal and informal speech levels
Korean marks politeness and formality directly in its grammar, through formal speech (존댓말) and informal speech (반말), in a way English mostly doesn't. Machine translation regularly flattens this distinction, since English has no equivalent structure to translate it into. A message that should read as respectful can come out sounding overly casual, or the reverse. Before sending a translated message to a boss, a landlord, or an elder, read it over yourself if you can, or ask a Korean speaker to check the tone.
Contracts and official documents
Don't rely on a translation app alone for a lease, an employment contract, or anything you're about to sign your name to. A mistranslated clause in a legal document can cost you money or create a dispute you didn't see coming. Get a human translator or legal advice for documents like this instead of trusting an app's output as final.
Medical situations
For anything medically serious, a translation app is not a substitute for a human interpreter. Seoul's city government built a medical interpreter dispatch program, called MeSic (동행 의료통역지원단), specifically because of how much a language barrier affects understanding in a medical setting. A 2020 study by the National Human Rights Commission, cited by the city, found that only 24.5% of migrants understood a doctor's explanation well when communicating without an interpreter, compared to over 90% who understood it with one.
MeSic provides trained medical interpreters across ten languages, bookable through Seoul's foreigner portal, for up to four hours per session and four sessions per year per person, aimed at situations like surgery, hospitalization, or a serious diagnosis. If you have an appointment like that coming up, book a human interpreter ahead of time rather than planning to translate on the spot.
