How to Merge PDF Files
Merging PDFs concatenates pages from multiple source documents into a single output file. The merge order follows the order you select files — drag to reorder before processing when the tool supports a queue.
Best practices
Ensure all inputs use the same page size when possible to avoid awkward scaling. Remove password protection first. For hundreds of files, process in batches to stay within browser memory limits.
Privacy
Choose tools that process locally so confidential contracts never leave your device. Weblexia PDF tools run entirely in your browser.
