5 common mistakes when using a PDF merge tool:
Uploading Large Files Without Checking Size Limits 📁
Many users try to merge very large PDFs at once, which can slow down the tool or even cause it to fail. Always check the file size limits of the tool before uploading.
Merging in the Wrong Order 🔄
PDFs are merged in the order they are uploaded. A common mistake is not arranging files correctly beforehand, leading to pages appearing out of sequence.
Ignoring File Compatibility ⚠️
Some PDF merge tools have trouble with certain types of PDFs, such as scanned images or password-protected files. Always check compatibility or unlock PDFs if needed.
Not Checking the Output Quality 🧐
After merging, users often skip verifying the final PDF. This can result in missing pages, formatting issues, or loss of clarity. Always preview the merged PDF.
Overlooking Privacy & Security 🔒
Uploading sensitive or confidential documents to online tools without encryption or secure protocols is risky. Always use trusted, secure services, and consider offline tools for sensitive files.
