PDF Tools at a Glance
Whether you need to combine documents, shrink file sizes, rearrange pages, or convert between formats, there is a browser-based tool for it. StackConvert's PDF tools handle all of these tasks without requiring signups, installs, or subscriptions. Most processing happens locally in your browser, so your files stay on your device.
Below is a quick overview of each tool and what it does best. For step-by-step instructions, tips, and detailed comparisons, follow the links to each dedicated guide.
Merge PDFs
Combining multiple PDF files into one is probably the most common PDF task. Whether you are assembling contract pages, joining scanned documents, or putting together a portfolio, merging saves you from juggling separate files.

Split PDFs
Sometimes you only need a few pages from a large document, or you want to break a long PDF into separate chapters or sections. Splitting lets you extract exactly what you need without affecting the original file.

Compress PDFs
Large PDF files are a headache for email attachments and uploads. Compression reduces file size while keeping the content readable. This is especially useful for image-heavy documents like presentations or scanned pages.

Reorder PDF Pages
Pages end up in the wrong order more often than you would think - scanned batches, combined files, or documents assembled from multiple sources. A reorder tool lets you drag pages into the correct sequence without recreating the entire document.

Word to PDF
Converting Word documents to PDF is standard practice before sharing files externally. PDF preserves your formatting across every device and operating system, so recipients see exactly what you intended.

PDF to Word
When you need to edit a document that only exists as a PDF, converting it to Word format is the fastest path. This is common with contracts, forms, and reports that need revisions before being finalized.

Picking the Right PDF Tool for Your Task
With several tools available, choosing the right one depends on what you are starting with and what you need as output. Here is a quick decision guide:
- You have multiple files and need one file - Use Merge. This covers combining contracts, assembling reports from sections, or joining scanned batches into a single document.
- You have one file and need parts of it - Use Split. Extract specific page ranges, pull out a single chapter, or separate a combined document back into its components.
- Your file is too large to share - Use Compress. Best for files with embedded images, scanned content, or high-resolution graphics. Text-only PDFs are usually small already.
- Your pages are out of order - Use Reorder. Faster than splitting and re-merging. Just drag pages into position and export.
- You need to lock down formatting before sharing - Use Word to PDF. Guarantees your document looks the same on every device.
- You need to edit a locked document - Use PDF to Word. Gets you an editable version so you can make changes and convert back when done.
If your task involves more than one step - say, splitting a document, reordering the extracted pages, and then merging them with another file - just run the tools in sequence. Each one outputs a standard PDF that works as input for any other tool.
FAQ
Can I use multiple PDF tools in sequence on the same file?
Yes. Each tool outputs a standard PDF file. You can compress a document, then merge it with another file, then reorder the pages - any combination works.
Is there a file size limit for these tools?
Since most processing happens in your browser, the practical limit depends on your device's memory. Modern laptops and phones handle files up to 100 MB without issues. Very large files may take longer to process.
Do these tools work on mobile devices?
Yes. All PDF tools run in the browser and work on phones and tablets. The interface adapts to smaller screens, and the processing is the same as on desktop.
What file formats are supported besides PDF?
The conversion tools support Word documents (DOCX), and the images-to-PDF tool accepts common image formats like JPG and PNG. For all other tools, the input and output format is PDF.
