How it works
The editor parses your file with the same gettext PO engine Wayline uses for localization, lists every source string beside an editable translation field, and re-serializes the catalog when you download — preserving translator comments and each entry’s message context (msgctxt). Everything runs in your browser, so the file you open never leaves your device.
Frequently asked questions
What is a PO file?
A PO (Portable Object) file is the gettext translation format — a plain-text catalog of source strings (msgid) paired with their translations (msgstr), used by countless apps, games, and frameworks to localize their text.
Can I edit a PO file and re-download it?
Yes. Load a .po (or .pot) file, edit any translation in the msgstr column, and click Download .po to get the updated catalog back — no install, no sign-up.
Is this free, and does my file get uploaded?
Yes, it is free with no sign-up, and nothing is uploaded — the file is parsed, edited, and re-serialized entirely in your browser.
Does it preserve comments and context?
Yes. Translator comments and each entry’s message context (msgctxt) are preserved through an edit-and-download round-trip, so the catalog stays intact.
