Frequently Asked Questions
What makes spf.io’s Slides Translation different from other presentation translation tools?
Spf.io’s multilingual presentation tool allows you to present multilingual slides from a single presentation without managing separate slide decks for each language.
Simply upload and automatically translate your file, and spf.io lets you present seamlessly on big screens, mobile devices, or live streams in multiple languages—all from a single source.
You can also review and refine translations, ensuring accuracy while saving time. This makes it easy to deliver live translated presentations to multilingual audiences. The system automatically applies your edits to the rest of your file and future slides, saving you significant time and improving consistency across presentations.
What languages does spf.io support for slide translation?
Spf.io supports 80+ languages for slide translation. View the complete language matrix on our Supported Languages page.
Does Slides Translation preserve the layout or formatting of my original slide file?
Yes, Slides Translation maintains your original layout, including the placement of text, images, videos, and tables. Once you finish reviewing the translations, you can download your multilingual slides in the same file format as the original file.
Can I display captions when presenting my slides?
Yes. You can display real-time captions alongside your slides during presentations.
Captions can be positioned to avoid blocking content, either on top or bottom of the screen, while audiences can view translations on their own devices.
Follow this guide on how to display output on a big screen or an extra display.
How many team members can collaborate with me?
Spf.io is priced on usage levels rather than per user. This means you can invite as many collaborators as you need to post-edit the translations of your slides.
We built it this way because we believe in community-sourced translation. Many organizations need to make their content available in many languages. To make that affordable, we empower communities with the tools they need to distribute the work among their own staff, volunteers, and members.
Each translation is linked to its source, allowing you to manage it as one logical unit. Your translators or team members can easily review and edit the translation for each target language.
These collaborative features save a lot of time and effort and make delegating work throughout your community a joy rather than a pain.
