Online PDF Tools
Practical online tools for common PDF tasks, including reading, merging, compressing, splitting, rotating and extracting pages from supported PDF files.
PDF Tools for Common Document Tasks
Choose a PDF utility based on the operation you need to perform. Each tool has its own supported features and processing limitations.
PDF Reader
Open and read supported PDF documents in a web browser when you need to view a file without using separate desktop PDF software.
Open PDF Reader →PDF Merge
Combine multiple supported PDF files into a single document when you need to organize related files together.
Open PDF Merge →PDF Compressor
Reduce the size of supported PDF documents for storage, transfer or sharing. The resulting file size depends on the original document and processing options.
Open PDF Compressor →PDF Splitter
Split a supported PDF into smaller documents or work with selected pages from a larger file.
Open PDF Splitter →PDF Rotator
Change the orientation of supported PDF pages when pages appear sideways or need a different viewing orientation.
Open PDF Rotator →PDF Page Extractor
Extract selected pages from a supported PDF and create a separate PDF containing the pages you need.
Open PDF Page Extractor →Working With PDF Documents
PDF is a common document format used for reports, forms, manuals, invoices, applications, presentations and many other types of digital documents. A PDF can preserve the structure and visual layout of a document when it is shared between different devices and applications.
Although PDFs are convenient for distribution, everyday document tasks can still require additional processing. You may need to combine several documents, reduce a large file, separate selected pages or change the orientation of a page.
Atlasaro provides separate PDF utilities for these common operations. The tools are designed around individual tasks so you can select the function that matches the problem you are trying to solve.
Read PDF Documents Online
A PDF reader is useful when you need to open and view a document without adding another desktop application to your workflow.
The PDF Reader is intended for viewing supported PDF documents through a web browser.
If a particular PDF contains unusual elements or uses features that are not supported by the tool, the document may not display exactly as expected. For important documents, keep the original file available.
Combine Multiple PDF Files
When related information is stored in several PDF files, combining the documents can make them easier to organize and share.
The PDF Merge tool is designed to combine supported PDF files into one document.
Before merging documents, check the order of the files and make sure that the selected documents are the ones you want to include in the final PDF.
Reduce PDF File Size
Large PDF files can take longer to upload, download, store or send. Compression can reduce the amount of storage required by a document.
The PDF Compressor is designed to reduce the size of supported PDF documents.
Compression results are not identical for every document. The final file size can depend on factors such as the original PDF structure, embedded images and other document content.
Split a PDF or Work With Selected Pages
A long PDF may contain more pages than you need for a particular task. Splitting or extracting pages can help create a smaller document containing only the relevant material.
The PDF Splitter can be used to work with selected pages or divide a supported PDF into separate documents.
If you need only a particular set of pages in a new PDF, check the available page-selection options before starting the operation.
Rotate or Extract PDF Pages
Page-level operations are useful when the document itself is fine but individual pages need to be adjusted or moved into a separate file.
Correct Page Orientation
Pages can sometimes appear sideways because of the way a document was created or scanned. The PDF Rotator is designed to change the orientation of supported PDF pages.
Keep Only the Pages You Need
If you need a smaller document containing selected pages, the PDF Page Extractor can create a new PDF from the pages you choose.
Which PDF Tool Should You Use?
Start with the specific document operation you need to perform.
You only need to view a PDF
Use the PDF Reader when the main task is opening and reading a supported document.
You have several PDFs to combine
Use PDF Merge when related documents need to be collected into a single PDF file.
The PDF is too large to share conveniently
Use PDF Compressor to try to reduce the size of a supported document. The amount of reduction can vary between files.
You need only certain pages
Use PDF Splitter or PDF Page Extractor when you need to separate selected pages from a larger document.
Pages have the wrong orientation
Use PDF Rotator when supported pages need to be turned to a different orientation.
The document is important
Keep an original copy before processing an important document. This gives you a backup if the resulting file does not meet your needs.
Things to Check Before Using a PDF Tool
Keep a Backup
If the original PDF is important, keep a separate copy before making changes or processing the document.
Check Compatibility
Review the individual tool page for supported file types, page limits, file-size restrictions and other available options.
Review the Result
After processing a document, open the resulting PDF and check the pages, orientation, text and other important content before sharing it.
Important Information
PDF processing can affect the structure, file size, page arrangement or other characteristics of the resulting document. The result can depend on the original PDF and the operation being performed.
File handling and processing methods may differ between Atlasaro tools. If a document contains sensitive or important information, review the individual tool page for available information about file processing before using it.
