When you would use this

Situations, not settings.

An English announcement for readers in Kolkata or Dhaka
Paste the text and take the Bangla script. The translator does not pick a regional variety, so a Bengali reader should choose the wording where usage differs.
A subtitle track for a Bengali-speaking audience
Drop the English .srt. The dialogue becomes Bengali, the cue numbers and timings stay exactly as they were, and the file is named with -bn before its extension.
Customer feedback in English to share with a Bengali team
Drop the .csv export. The comment column is translated cell by cell and the rating and date columns are copied through, so the sheet still sorts and filters.

How it works / no cloud

A conversion engine, not an upload form.

filetity hands the text to the translator built into Chrome, which runs a translation model on your device rather than on a server. Plain text goes a paragraph at a time, because a model given half a phrase answers about half a phrase: a wrapped line that read "Most / of the staff work from home" came back as "Over-employees work from home" until the paragraph was joined. A subtitle goes a cue at a time, for the same reason, which means a two row cue comes back as one row and the player wraps it. Italics and colour inside a cue are kept when the translation brings them back intact and dropped when it does not, because a broken tag is worse than none. A CSV goes a cell at a time, where the pieces really are separate. The first time English to Bengali is used, Chrome downloads that language pack from Google, once, and keeps it; the page shows the download and says so, because it is the one moment anything crosses the network. Your text never does: measured with the browser's own network log, translation makes zero requests. The limit is the model, not the plumbing. In a 20 sentence English to Hindi test read by a person, 16 were clean and 2 changed meaning: "with the wifi off" lost the "off", and "out of milk" came out as milk that had run out of something. Read the result before you rely on it.

Straight answers

No accordion. Nothing hidden.

Is it free?
Yes, with no watermark and no page limit.
Does it need an account?
No. There is no account system.
Is my file processed on my device?
Yes. Chrome's built-in translator runs on this device and the page makes no request of its own. The one download is Chrome fetching its language pack from Google, once per language, and your text is not part of it.
What formats are supported?
English text, typed or pasted, or a .txt, .md, .srt, .vtt or .csv file in. Bengali out, in Bengali script, in the same format.
What are the limits?
Chrome 138 or newer only; Firefox and Safari have no on-device translator and are refused with a message. Quality is good enough to understand a document and not to publish one unchecked: 16 of 20 test sentences were clean, 2 changed meaning. Plain text is translated a paragraph at a time, so a hard wrapped paragraph comes back as one line rather than in its original wrap.
Does it work on mobile?
Yes, on any modern mobile browser. Large files are limited by the memory the phone gives the browser.
Does it work offline?
Yes, once Chrome has the language pack. The first use of a pair downloads it; after that the page translates with no network connection.
Is this Bengali or Bangla?
The same language. Chrome's pack is labelled Bengali and its code is bn; what it writes is Bangla script, as used in West Bengal and in Bangladesh. The translator does not pick a regional variety, so a word that differs between Kolkata and Dhaka usage comes out one way with no option to choose.
How accurate is the Bengali?
Not measured here. The number this site can quote is for English to Hindi, 16 clean sentences in 20 and 2 that changed meaning, on the same on-device translator. Bengali has not had that read yet, so the output is a draft until a Bengali reader has been through it.
Can I use it for a Bengali subtitle track?
Yes. Drop the English .srt or .vtt and the spoken lines come back in Bengali with every cue number and timing line untouched. The saved file has -bn before its extension and keeps the original's timing exactly.
Does the Bengali text leave my device?
No. The translation runs inside Chrome on this device, and the page makes no request of its own. The only network event is Chrome fetching its English to Bengali pack from Google the first time, which carries nothing of yours.
