I totally get that situation, it happens to me more often than I’d like. I work with documents almost daily, and sometimes clients send files in the wrong format or with missing pages, so I need to fix things quickly. I’ve been using online PDF tools for a while now because they save me from constantly installing and updating heavy programs. What I usually do is keep a couple of trusted browser tools bookmarked so I can switch between them if one is slow or overloaded. For quick edits like merging invoices or converting reports, they’re honestly more than enough, and I rarely need anything more advanced unless it’s a big project with complex formatting.
