Show humans behind the product
About pages, support emails, and changelog posts signal you are not a fly-by-night wrapper around malware.
Security headers and HTTPS badges
HSTS, CSP, and clean Lighthouse security audits reinforce technical trust for savvy visitors comparing tools.
Transparent limits sell better than hype
Explaining what you cannot do (DRM, private videos) filters out bad fits and reduces chargebacks.

Caching and repeat visits on static tool pages
Long `Cache-Control` on CSS and JS cuts repeat bandwidth. Version filenames only when you ship breaking changes so return visitors keep warm caches.
HTML can stay short-cache or revalidated so editorial fixes propagate within hours.
Thumbnail fidelity after re-encoding
Re-encoding can soften fine text in thumbnails. If your pipeline preserves poster frames separately, mention that in release notes for creator audiences.
PNG snapshots are heavier than JPEG; pick defaults for mobile-first visitors.
Explaining aspect ratio letterboxing
Downloads may include black bars if the source was already pillarboxed. Offer a crop tool only if licensing and ethics allow, and warn about cutting subtitles.
Many viewers prefer original framing for archival honesty.
