PDF guides
Short, straightforward explanations so you know what to expect from each PDF tool.
How to merge PDF files in order
Choose the Merge PDF tool, add at least two PDF files and use the up/down controls to set their order. Click Merge PDF to create one document. Check the final page sequence before sharing it.
Choosing a PDF compression level
Extreme rebuilds PDF pages as lower-resolution JPG images. Recommended also rebuilds pages as images, but at a higher resolution and quality. Both can shrink photo-heavy or scanned PDFs, but they remove selectable text, working links and interactive form fields. Less compression uses lossless PDF structure optimization and normally preserves searchable text and links, although existing digital signatures may be invalidated by rewriting the file. PDFLife returns the original PDF if the result would be larger. Always inspect the output before sharing it.
What browser-side processing means
In-browser processing means your PDF data is read and manipulated by code running locally in your web browser. Your selected files are not uploaded to PDFLife servers. Your browser still requests website assets from the host and third-party libraries from their CDNs. Review your organization’s policies before working with sensitive documents.
Page ranges explained
Type individual pages separated by commas, such as 1,3,5, or a range such as 2-6. The first page is number 1. In Reorder pages, the sequence you enter becomes the output page order.
Current processing limits
Files must be no larger than 50 MB each. Merging and image combining accept up to 35 files; PDF-to-image export and image-based compression are limited to 40 pages per batch. Large PDFs can use substantial browser memory.
