Translate More Than Just Your PO Files

Translating resource files is one thing. But what about your readme.txt, release notes, emails to users, and WordPress.org description?

PTC’s Paste to Translate feature handles all the text that lives outside your PO files. Because PTC already knows your product, every translation uses the same terminology and tone.

Fits your existing workflow

Connect PTC to GitHub, GitLab, or Bitbucket to get continuous translation updates. Or, integrate with your CI/CD pipeline.

Linguist-backed quality

Our linguists continuously refine the AI, so your translations outperform human translators and generic LLMs.

Frequently Asked Questions

Can I use PTC to translate other file formats?

Yes. Besides .po and .pot files, PTC supports a wide range of file formats, including JSON, string.xml, iOS .xcstrings, and more. See the full list of supported resource file formats.

Can I get .mo files back as well?

Yes. By default, PTC returns translations in .po files, but you can configure it to also output .mo, .l10n.php, or .json files.

What languages can I translate PO files into?

For the full list of the 35+ languages PTC supports, see our supported languages page.

How is PTC different from other PO file translators?

The big difference is context. Most tools see a string like “Run” and translate it without knowing whether it means run a scan or to go for a run. PTC learns your terminology and audience first, which is why 99.5% of translations go live without any edits.

Does PTC integrate with localization workflows?

For continuous localization, PTC can connect to your GitHub, GitLab, or Bitbucket repository. When it detects changes to your .pot file, it translates the updated strings and delivers them back as a merge request. You can also use the PTC API to integrate localization into your CI/CD pipeline.

How do I load the PO/MO file translations into my WordPress theme or plugin?

You have two options: bundle the translations with your plugin or theme, or import them to WordPress.org if your project is hosted there. Our guide to importing theme and plugin translations covers both options in detail.

Why aren’t my PO file translations showing up in WordPress?

The most common cause is mismatched text domains. Your code, plugin header, file names, and load_plugin_textdomain() call must all use the exact same text domain. Other common issues include.mo files aren’t in the correct directory or community translations overriding translations bundled with your theme or plugin.

For detailed troubleshooting steps and solutions to specific scenarios, see why your translations might not be showing.
