German employers often ask for certificates, but stuffing every PDF into the first email creates noise. Lead with the items that prove you can do the advertised work: relevant degree documents, key safety or welding qualifications if the role needs them, and language certificates only when the vacancy states a level.
Secondary items — short online courses, expired credentials, or certificates unrelated to the role — belong in an appendix or on request. If you are relocating, clarify which documents are originals versus certified copies once an employer asks; do not flood the first application.
