About this tool
Translate PDF uses the browser’s on-device translator when it exists. If it does not, the control stays disabled. Text is not sent to a translation website. Translation can be wrong on names, dosages, and legal terms. Treat the result as a reading aid and keep the original. Scans without a text layer are not translated, and this version will not OCR them first in secret.
Translate PDF stays on this device. The download is the copy you keep, and Weesize does not store a second one. Close the tab when you are finished and the bytes are gone.
- No upload: translation either runs in the browser’s own model or it does not run.
- Speed: the file does not travel to a server and back, so the wait is only the work itself.
- Quality: the original is kept when the new file would be worse or is not actually smaller.
FAQ
Does “Translate PDF” upload my file?
Translate PDF reads the file in this tab. There is no upload step and no account.
What will “Translate PDF” actually change?
You get a reading aid, not a certified translation. The original PDF is the record. A missing local translator means no translation.
When is “Translate PDF” the wrong job?
Do not act on a translated dose or a legal term without a person who can check it.
How do I check the result of “Translate PDF”?
Read the original beside the translation. If a name changed meaning, ignore the translation for that line.
Can I run “Translate PDF” with Wi-Fi off?
Load this page, then turn Wi-Fi off and run Translate PDF again. A finished result is the proof that the file was not sent anywhere.
