Can I use this PDF Writer from anywhere?


Anywhere and everywhere! Smallpdf is a cloud-based SaaS application. As long as you have installed an internet browser and have online access, you can print to PDF and vice versa, from any operating system, including Windows, Mac, and Linux. To appease everybody, there exist mobile-compatible versions as well for those who write files on the go!

An offline PDF Writer from Smallpdf has also been in the works, which is split into three different tools, titled 'PDF to Office', 'Office to PDF', and 'PDF to Image.' The only tool absent is for Image to PDF, which we aim to push out as soon as we have it optimized. With the offline app, you can promptly save files from one format to another, sans the upload speed, and, thus, less time spent on the rewriting process. As such, this is much quicker than relying on a virtual printer to save PDF files.

Additional tools to enhance PDFs


Once you have written the content of a document to PDF format with tour free PDF software, there exists over 15 over tools that you can use to modify your new PDF and fit your usage. Some includes:

  • Compress - in case the new file's size has increased.

  • Edit - annotate, blackout text, or add shapes to your PDF.

  • Merge - combine multiple PDF pages into one.

  • eSign - to create e-signatures and sign PDFs.

  • Reader - in case you need to switch it up from Adobe Acrobat.
