English to Indonesian Translation: Free AI Translator With Tips

Your text is never stored. Core features free forever.
Translate English into Indonesian with the free AdeptWrite AI translator, already set to this pair. Indonesian has no verb tenses, plural endings or articles, so a good translation rebuilds the sentence instead of swapping words, and the choice between formal and casual register matters more than grammar. Paste your text, pick a natural, formal or casual tone, and check names, numbers and technical terms before you send or publish it.
Tips for this language pair
- Choose the register first. Formal writing uses Anda and saya, while casual speech uses kamu, aku and nggak. Pick Formal for a manager, school or official letter, and Casual for chat with friends.
- Do not translate tenses word by word. Indonesian marks time with words such as sudah, sedang and akan, or leaves it to context, so "I have finished" becomes "Saya sudah selesai".
- Use the standard spelling of loanwords: praktik, risiko, analisis and apotek, not praktek, resiko, analisa or apotik. The references are EYD Edisi V and the KBBI.
- Translate "we" carefully. Indonesian has kami, which excludes the listener, and kita, which includes them. The wrong choice changes who is part of the plan.
Example translations
| Original · English | Translation · Indonesian | Why it is translated this way |
|---|---|---|
| Could you send me the report by Friday, please? | Bisakah Anda mengirimkan laporannya kepada saya paling lambat hari Jumat? | Formal register with Anda. "By Friday" becomes "paling lambat hari Jumat" (no later than Friday), which keeps the deadline clear. |
| I have already submitted my application. | Saya sudah mengirimkan lamaran saya. | No past tense: sudah marks that the action is complete. "Lamaran" is the usual word for a job application. |
| We are closed on public holidays. | Kami tutup pada hari libur nasional. | Kami excludes the customer, which is right for a business notice. "Hari libur nasional" is the standard phrase for a public holiday. |
| The risk assessment was approved yesterday. | Penilaian risiko disetujui kemarin. | Standard spelling risiko, not resiko. The passive disetujui mirrors the English passive naturally. |
Frequently asked questions
Is the English to Indonesian translator free?
Yes. It is free and needs no sign-up. Paste a few paragraphs at a time (the tool shows the limit per request), choose a natural, formal or casual tone, and translate longer documents section by section. Your text is not stored or used to train models.
Should I use formal or casual Indonesian?
Use formal Indonesian (Anda, saya) for work, school, official letters and anyone you do not know, and casual Indonesian (kamu, aku) for friends and social media. The tone selector lets you choose before you translate.
Can I trust it for official documents?
The translator uses AI, so it can miss names, numbers and specialist terms. For contracts, visas, medical or legal documents, have a qualified human translator check the result before you rely on it, and read names and figures twice. For Indonesian spelling, try the Indonesian spell checker, which follows EYD V.
