Frequently asked questions

Everything you need to know

Why is accurate manual translation critical?
Accurate manual translation matters because users rely on instructions, maintenance steps, and warnings to operate products correctly. OpenL helps retain diagrams, numbered steps, warning blocks, and document structure, but safety-critical or regulated content should be reviewed by a qualified subject-matter expert before use.
Will diagrams, warning symbols, and numbered steps stay intact after translation?
OpenL retains diagrams, tables, warning symbols, numbered procedures, headers, styles, and document structure where the source format supports them. Text expansion can change line and page breaks, so review the exported file before publishing. Safety-critical wording and technical terminology should be checked by a qualified subject-matter expert. If the result is not satisfactory, contact us to request a refund.
