How to turn PDF into MOBI?

You can convert .pdf to .mobi format by uploading the file to our platform and waiting a few seconds for our service to process it. Then, download the new MOBI file to your device. While this process is super simple, here are some additional tips for smooth sailing:

• Optimize your PDF for smaller file sizes:
Our free PDF to MOBI converter can handle files up to 50 MB in size, which is more than enough for most eBooks. However, if your PDF is particularly large, consider compressing your file compressor before conversion. This can decrease file size without compromising quality.
