What Users Say About PDF Awesome

Not gonna lie
Not gonna lie, I was skeptical about "free online PDF tools" after trying a few sketchy ones that either watermark everything or crash mid-upload. PDF Awesome actually just worked. Used it to merge my project documentation — multiple files, different formatting — into one report for my web dev coursework. It held the formatting together better than I expected, and I didn't have to make an account just to download the final file. Small thing, but it mattered at 1am before a submission deadline.

Your Questions About PDF Merging, Answered
Learn more about merging and combining PDF files with PDF Awesome.
How do I merge PDF files online?
Upload two or more PDFs by selecting “Choose Files” or dragging and dropping them into the tool. A file card appears for each upload, allowing you to drag the cards into your preferred order before clicking “Merge PDF.” The combined PDF is ready to download within seconds, with no software installation required.
How many PDF files can I combine in one task?
No-account users can merge up to 10 files and 100 MB total per task. Free users can merge up to 30 files and 200 MB total per task. And Pro subscribers can combine up to 700 PDFs with up to 1 GB per task, making it suitable for large legal bundles, project archives, or report sets. If you need to divide a large document into separate files afterward, you can use Split.
Does combining PDFs affect their original quality?
No. PDF Awesome preserves the original resolution, fonts, vector graphics, and embedded links from each source PDF. The files are combined into one document without changing the quality of the original content. You can even edit the resulting PDF if further changes are needed.
Can I combine PDF files from a mobile device?
Yes. PDF Awesome runs directly in your browser. So there is no app to install. The tool works on iPhone, iPad, Android, Mac, Windows, and Linux. In addition, you get reorder controls that also work on touch screens.
Can I change the order or remove files before merging?
Yes. You can drag the file cards on the board to determine how the PDFs will appear in the final document before merging. Each file is added with its complete page range in the order you choose. For changes to individual pages, use the delete pages or rotate pages tools.
Is it safe to upload confidential documents?
Yes. All uploads are protected with 256-bit SSL encryption during transfer. Files are processed on isolated servers and permanently deleted within 60 minutes, and they are not stored, read, or shared. PDF Awesome is GDPR compliant and built in alignment with ISO/IEC 27001 security principles.
Can I combine Word documents or image files directly?
Images and Word documents need to be converted to PDF before they can be merged. Use the Word to PDF or Images to PDF tool to create PDF files first, then upload those files to the merger.
Are bookmarks and clickable links retained after merging?
Yes. Internal bookmarks, table-of-contents entries, and clickable hyperlinks from each source PDF are preserved in the merged document. External URLs are also retained.
Can PDFs with different page dimensions be merged together?
Yes. Different PDF page sizes, orientations, and layouts can be combined in the same document. The merged file keeps each source page’s original dimensions and layout.
Can I merge a password-protected PDF?
If security settings prevent a PDF from being merged, you’ll need to remove those restrictions first. You can then upload the accessible, unlocked PDF with your other files and merge them together.
