Office to PDF
This function is designed for creating PDF file from Microsoft Office documents. You can upload a Word document, Excel Spreadsheet or PowerPoint file. Our service will output a PDF file for you, keeping all the original formatting and content.
Compress PDF
Reduce PDF file size by removing the unnecessary data, and reduce the image quality and dpi within the PDF. The lower dpi and quality you choose, the smaller file will be output, so you can choose the balance between quality and file size by yourself. If your PDF file is text-only without any image, or it was compressed before, the file will not be compressed any more.
Combine PDF
You can upload multiple PDF files from your local folder, then click 'Combine PDF' button to merge files. The total file size of your uploaded files should be smaller than 20MB. Please make sure that your uploaded files are not damaged or encrypted, or the process may not work.
Split PDF
It's an easy way to extract pages from a PDF, or split a large files into smaller files. You can choose the output options on the setting area. If you want to extract particular pages, please enter the page or page range in the text field, for example, 1,3-5,10. Please use comma to separate the page numbers.
Encrypt PDF
You can protect your PDF file by adding an open password, or setting restrictions. Technical speaking, there are two passwords for PDF. You can set an open password, your reader must enter the open password before getting access to the file and viewing the content. Or you can set an owner password, so you can set restrictions for some functions, such as copying and printing. Please note that the owner password and open password can not be the same.
Unlock PDF
If the PDF file you uploaded requires open password, our service can't crack it. It is not a brute-force cracking method, it may take years to crack a simple password. But if you know the open password and you don't want it any more, you can enter the correct open password, and remove it from your files.
If your PDF file is protected by owner password, that means you can view the content, but you can't edit, print or copy the content, our service can remove all the limitations. Simply upload a secured PDF, and the application will return a PDF without any limitations.
