How many pages can I include in a merged PDF?
To combine PDF online with our tool, you can upload up to 15 files in a single attempt. While the number of pages isn't limited, it's the number of files that you need to consider.
Please note that you can only stitch PDF files with other PDFs. If your files are in a different file format, you'll need to convert them using our Converter tool before putting them together.
Can I delete or reorder pages after I merge files?
There are two ways to organize PDF pages within your compiled document.
Option 1. While you're uploading the files you want to merge, you can reorder them however you want. However, this won’t change the order of pages within the individual files.
Option 2. If you need to change the order of pages after using the PDF merge tool, we recommend the following steps:
- Upload the combined file into our PDF Editor tool or find and open it in your account.
- Reorder the pages by dragging the thumbnails on the left.
- Save the edited version with the correct page order.
- Download it to your device.
How can I access my PDF once it is merged?
When you attach multiple PDFs to one, the resulting document will automatically download to your device and be saved in your PDF Guru account. This way, if you accidentally delete it or need to free up space, you can easily retrieve it from your account.
Will the quality of my PDF files be affected after merging them?
Our PDF binder ensures that the quality of your documents remains intact, no matter how complex they are. However, keep in mind that when you concatenate PDFs that are larger, it will also result in a heavier merged file. To reduce the file size with minimal-to-no quality loss, you can use our PDF compressor.
