Keep in mind that PDF is a format that’s meant to be portable (that’s the “P” in PDF) and thus lightweight. In the end, there just isn’t anything to gain from such a disproportionally large file. You may want to consider compressing your PDFs before merging them in this case. Having said that, if you are merging multiple files that are closer to the 5GB limit, you may experience slow download speeds while waiting for the process to complete.

If you happen to have a PDF that exceeds this limit, fear not, you can use our Compress PDF tool to shrink it down before binding them all together. We can process files that are up to 5GB in size, which should be more than enough for most documents in PDF format. If you’d like to find out more about this, check out our Privacy Notice. We’re also an ISO/IEC 27001 and GDPR-compliant company, which means we follow all the necessary protocols to ensure that your documents and information are safe when you use our services. With our eSign tool, the only exception to this rule, uploaded PDFs are stored for up to 14 days while awaiting a signature. In addition, all files uploaded to our merge tool are deleted from our protected AWS servers after an hour. Security is our top priority, which is why we use TLS encryption to keep your information safe. This makes it a great tool for professionals who need to work remotely or for students who need to access their notes while studying. With the mobile app, you can easily access your PDFs on the go and make any necessary changes. If you’re more of a mobile phone user, you can also choose to download our mobile app on Android or iOS devices. The Windows offline app gives you the same access to the merge tool, with the added bonus of your files never leaving your local drive.Īdditionally, the app comes with a convenient PDF reader so you can view and read your newly merged PDFs wherever you are. If you’re on the move a lot and don’t always have internet access, or if you just prefer not to upload your documents, you can always download our free software directly to your computer.
