1. OmniDoc free document translationour site
Free limit: Free, uses no credits; no monthly cap; up to 2000 pages per file; free jobs wait in a queue; free account required
PDF and LaTeX come back as a bilingual version and a translation-only version; Word, Excel, EPUB and the rest come back as translated files that keep paragraphs, tables and styles; PowerPoint as a translated deck (no bilingual version for slides yet). Only you can see the files you upload and their results. For more than 2000 pages, or when you are in a hurry, the desktop app for Windows, macOS and Linux has no page limit and no queue.
