Practical PDF guides, not fluff pages
Filegiga guides are written around real file tasks people actually need help with. The goal is simple: answer the question clearly, explain the workflow in plain language, then get you into a working tool fast.
Need the file smaller, cleaner, or separated? Pick the job first, then the tool.
These pages are built to get you from question to action without drowning you in filler.
Every guide links directly into the right Filegiga tool so reading and doing stay connected.

Which guide should you start with?
If the file is too big to send, start with compression. If several files should become one packet, start with merge. If the document includes too many pages and you only need a section, start with split. That sounds obvious, but choosing the right workflow first usually saves more time than any tool tweak afterwards.
- Compress when size is the main problem.
- Merge when separate PDFs belong together.
- Split when the original document contains more pages than you need.
