Free Online PDF Tools

Merge multiple PDF files into one, split a PDF into separate pages, or extract specific page ranges. Drag and drop to reorder files before merging. Every operation runs through the pdf-lib library loaded into this page, so the documents you open here stay on your device instead of passing through an upload step. No account required, no file size limits, completely free. Works on any device with a modern browser.

What Are Online PDF Tools?

PDF (Portable Document Format) is one of the most widely used file formats for sharing documents, forms, reports, and presentations. While PDFs are designed to look the same on every device, editing and rearranging them usually requires specialized software. Online PDF tools solve this problem by letting you merge, split, and reorder PDF pages directly in your browser without downloading or installing any application.

This free tool processes your PDFs entirely on your device using the pdf-lib JavaScript library. Your files are never uploaded to a remote server, which means your sensitive documents stay private. Whether you need to combine multiple reports into a single file, extract specific pages from a long document, or rearrange the page order before sharing, you can do it all right here in seconds. There are no file size limits, no account requirements, and no watermarks added to your output.

How to Use This Tool

Choose your operation by clicking the "Merge PDFs" or "Split PDF" tab at the top of the tool.
For merging, drag and drop multiple PDF files into the upload area or click to browse your file system. Once loaded, drag the file cards to reorder them as needed, then click "Merge All."
For splitting, drop a single PDF file into the upload area. Enter a page range (for example, "1-3, 5, 7-10") to extract specific pages into one file, or leave the range empty to split every page into its own individual PDF.
The resulting PDF files download automatically to your device. Check the status message for details about page counts and processing time.

Key Features

Merge Multiple PDFs - Combine two or more PDF files into a single document. Drag to reorder the files before merging to control the final page sequence.
Split by Page Range - Extract specific pages by typing ranges like "1-5, 8, 12-15" to create a new PDF containing only the pages you need.
Split into Individual Pages - Leave the page range empty to automatically generate a separate PDF for each page, perfect for distributing single-page documents.
Complete Privacy - All processing runs in your browser using pdf-lib. Files never leave your device, making this safe for confidential contracts, financial records, and personal documents.
Drag-and-Drop Reordering - Rearrange files visually before merging with intuitive drag handles, so the final document matches your intended page order.

Frequently Asked Questions

Is there a file size limit for PDFs?

There is no enforced file size limit. Since processing happens in your browser, performance depends on your device's available memory. Most modern devices can handle PDFs up to several hundred megabytes without issues. Very large files may take a few extra seconds to process.

Are my PDF files uploaded to a server?

No. All PDF processing is performed entirely in your browser using JavaScript. Your files are read into memory locally, manipulated using the pdf-lib library, and the output is generated on your device. Nothing is transmitted over the internet at any point during the process.

Can I merge PDFs with different page sizes?

Yes. The merge operation preserves the original page dimensions of each source PDF. If one file has letter-sized pages and another has A4 pages, the merged document will contain both sizes exactly as they appeared in the originals.

What happens to encrypted or password-protected PDFs?

The tool attempts to open encrypted PDFs using the ignoreEncryption option, which works for most PDFs with basic restrictions like print or copy protection. However, PDFs with a strong user password that prevents opening may not be processable without first unlocking them with the correct password in a dedicated PDF viewer.
