PDFsam Basic rearranges complete PDF pages without sending the document to an online service. It can join several files, divide one file into smaller results, extract selected pages, rotate pages, insert another PDF at intervals, or interleave scans. PDFsam Basic changes page order and document structure; it does not rewrite a sentence inside a page, run OCR on a scan, or act as a full PDF editor. Every job creates a separate output file, so the source can remain untouched unless the user deliberately replaces it later.
Build a merge
The merge tool accepts complete documents or page selections from each input. A selection can combine single page numbers, closed intervals, and an open-ended interval that runs to the end. Each file keeps its own selection, which makes it possible to take a cover from one PDF, a chapter from another, and the remaining pages from a third without creating temporary extracts first.
Input order controls the result. PDFsam Basic does not decide which attachment belongs before another, and a valid job can still produce the wrong document when two sources sit in the wrong row. The output options also need a location and file name. Previewing the page count after the run is safer than assuming that a completed status means the chosen ranges described the intended pages.
Split by structure
PDFsam Basic can create a file after every page, after even or odd pages, after a chosen page number, or after a repeating number of pages. A size target produces approximate pieces rather than byte-perfect archives because PDF objects and shared resources do not divide evenly. Bookmark splitting follows the selected outline level, so a PDF with useful chapter bookmarks can become separate chapters without typing every boundary.
Bookmark rules depend on the source document. A scan with no outline gives the splitter no chapter structure, while inconsistent bookmark levels can create unexpected cuts. Page-range fields also require exact punctuation. A missing comma or an incorrect open-ended interval changes the selection before PDFsam Basic starts processing.
Repair duplex scans
A single-sided scanner often produces one file for front pages and another for back pages. The Mix tool alternates pages from those inputs to rebuild the original sequence. It can take more than one page at a time through the pace setting, and it can read one source in reverse when the scanner returned the flipped stack backward.
This operation has no way to recognize a front page by its content. The user must place the source files in the correct order and enable reverse on the right one. A mistaken reverse setting creates a finished PDF with a scrambled sequence, even though every page remains present.
Reuse a workspace
Workspaces save the current tool configuration for a repeated task. PDFsam Basic can reload one later or open a chosen workspace at startup. The workspace preserves the setup, not a guarantee that newly selected documents have the same page layout. A saved split rule that matched last month’s report can cut this month’s report at the wrong places when its bookmarks or page count changed.
Handle large files
Local processing keeps confidential documents off a remote server, but it moves the memory cost to the computer. Very large operations can stop with a Map failed or Java heap space error. The documented repair involves increasing the Java memory allocation in the PDFsam Basic configuration and restarting it. That manual edit is a practical limit for people expecting every large file to work merely because PDFsam Basic places no advertised size cap on the job.
