Hi Product Hunt! smallLab28 is an independent software studio building practical desktop software. We created PrivatePDF with one goal: make high-quality PDF translation possible without uploading your documents to someone else's server. Most cloud-based PDF translators require you to upload sensitive files, and many still struggle to preserve complex layouts. We wanted a desktop-first solution that keeps documents on your own computer while delivering translation quality comparable to modern cloud services. Before building the desktop app, we launched the web version at https://privatepdf.tech. Feedback from real users consistently showed that preserving document layouts matters just as much as translation quality. Those insights became the foundation for PrivatePDF Translator for Desktop. With PrivatePDF Translator, you can: Translate PDFs locally whenever possible instead of sending documents to external servers. Choose your preferred translation engine, including OpenAI, Gemini, DeepL (using your own API key), or use Google Translate for free. Customize output fonts to better match your translated documents. Preserve the original PDF layout as faithfully as possible. Rather than locking users into a single AI provider, PrivatePDF lets you choose the translation engine that best fits your quality, privacy, and budget requirements. If you'd like to try PrivatePDF: Web version: https://privatepdf.tech Desktop app: https://translate.privatepdf.tech We'd love to hear your thoughts: Which translation engine do you trust most for PDF translation? What has been your biggest frustration with existing PDF translators? What features would you like to see in future releases? Thank you for checking out PrivatePDF. We appreciate your feedback and look forward to hearing your thoughts.
