How to Merge PDF Documents on Your Phone
iLove PDF
Modern life is inseparable from mobile phones. Compared with computers, people are more inclined to study, view documents, transfer resumes, etc. on mobile phones, and can quickly process them anytime, anywhere. Therefore, our first choice is an online PDF merger tool that can be used on mobile devices.
iLovePDF works based on web pages, so you only need to enter the URL from your mobile browser. Both iOS and Android can be used smoothly without limitation.
1. In the mobile browser, enter "iLovePDF" to open the official website;
2. Select the first "Merge PDF" option;
3. Click the "Select PDF File" icon to upload all your PDF files. After uploading, click "Merge PDF", and the system will automatically process the merge.
4. Generally, files that are not too large can be merged within 1 minute.
It should be reminded that iLovePDF only allows 4 free merge actions per day. If you need to process many PDF files every day, I suggest you choose a professional PDF editor. Generally speaking, professional PDF editing software is equipped with functions such as PDF merging, splitting, OCR, text editing, and image editing. The following will introduce a Geek PDF editor that I often use recently.

Drag and drop one or more PDF files into the box on the Twilight interface, confirm the order, click Merge, and you can download the merged PDF to your device in a few seconds. This online PDF merger tool can run perfectly on different operating systems and is compatible with a variety of mainstream browsers, including Chrome, Safari, FireFox, etc.

Most of these online PDF tools work in a similar way, and the usage of this SmallPDF is basically the same as that of Flash PDF. Drag and drop your PDF or multiple PDFs into the frame on the page. When the page appears, you can start editing it. Then press the button below to download your PDF. When you finish merging your PDFs, SmallPDF's Yunrui server will process the file for you, so the process will not consume your computer's resources.
