I18nweb

I18nweb is an online i18n translation tool designed to translate structured files (JSON) and content documents (Markdown, TXT) into multiple languages while preserving the original file structure. It targets developers, localization teams, and content creators who need to convert site copy, blog posts, and i18n resource files for frameworks like Next.js, React and Vite. The service uses modern large language models (LLMs) and contextual prompts to produce localized translations that aim to be accurate and natural while avoiding line-by-line mechanical translations.

The product supports batch translation of JSON files, segmentation and contextual translation of Markdown or article content, an in-browser editor for checking and editing translations, and options to download single translated files or packaged results. The service operates on a free-credit and paid-credit model, and enforces limits (file size, number of files, language versions per request) for free users to control costs and ensure stability.

Key Features

Supported file types

Accepts .json, .markdown (md/mdx), and .txt files for translation.

Structure-preserving translation

Translates JSON and other structured files while keeping the original object/field structure intact rather than doing naive line-by-line changes.

Batch processing for JSON

Processes JSON translations in batches rather than strictly line-by-line to maintain context and consistency across keys.

Markdown/document segmentation

Segments Markdown and long-form documents appropriately and translates with background/context to improve localization quality.

LLM-powered localization

Uses large language models and contextual prompts to produce more localized and natural translations compared with basic machine translation.

In-browser editor

Provides an editor to review and edit translated output before downloading.

Download options

Supports single-file downloads or packaged downloads containing multiple translated files and language variants.

Translation options

Offers options like selecting languages, skipping specific object keys, and adding additional information to guide translation.

Credit-based consumption

Uses a credit system for paid translations with transparent per-character and per-batch consumption details.

Use Cases

Localizing web applications

Translating blog posts and articles

Translate Markdown-based blog posts and long-form content while preserving formatting and structure.

Bulk translation of documentation

Batch-translate multiple documentation files (JSON/MD/TXT) to accelerate localization of developer docs and help centers.

Content localization with review

Produce translations using LLM context and then review/edit in the integrated editor before publishing or exporting.

Integrations

Next.js

Compatible with JSON i18n resource files commonly used in Next.js projects for localizing site copy.

React

Vite

Benefits

Preserves JSON and Markdown structure to reduce manual rework and integration effort.
Improves localization quality by using contextual LLM prompts rather than simple literal translations.
Speeds up multi-language publishing with batch processing, an in-browser editor, and packaged download options.

Limitations

Free tier limits: size of files, number of files, and number of language versions per request are restricted.
Rate limits and request limits are enforced to ensure service stability; this may limit batch sizes for free users.
Because prompts and contextual information are used for better localization, larger translations can incur higher costs.
