PDF AI Translator: GPT-4, DeepL & Google

PDF Translate makes it easy to translate full PDF documents directly inside your browser. Upload a PDF, choose your source/target language, pick a translation engine, and get a high‑quality result without leaving the page.

What you can do:

Translate PDFs end to end with no copy/paste.
Drag & drop or click to upload (recommended up to 50MB).
Choose from multiple engines: Google Translate, Bing Translate, and premium options (OpenAI, DeepL Pro) for higher fidelity.
Keep formatting readable: preserve basic layout and text flow for easy review.
Track progress live: see upload, processing, and completion status as the file is translated.
Download results: get the translated PDF (single-column or dual-column) once it’s ready.
Multilingual support: popular languages like English, Chinese (Simplified/Traditional), Spanish, French, German, Japanese, Korean, Portuguese, Russian, Arabic, and more.
Account integration: sign in to unlock premium engines and higher usage limits. Users with “Unlimited Usage” or active/canceled-but-still-valid subscriptions can use premium engines during the validity period.
How it works:

Open the extension popup and log in (if you need premium engines).
Pick source and target languages.
Select a translation service (basic or premium).
Upload your PDF and start translation.
Follow the progress indicator; download when finished.
Why use PDF Translate:

Fast setup: no separate apps or manual text extraction.
Flexible engines: switch between basic and premium models depending on quality needs.
Friendly limits: daily free credits for guests; subscribers get higher or unlimited usage.
Privacy-aware: files are only used to provide the translation; no extra data collection beyond what’s needed for the service.

Tips:

Log in first if you need premium engines.
For best results, keep PDFs under 50MB and use clear, text-based PDFs (scanned images may reduce quality).
If you have “Unlimited Usage” or an active/canceled-but-still-valid subscription, premium engines will be available during the validity period.
