Merge PDF Files

Simply upload two or more PDF files by dragging them into the upload area, clicking to select them from your device, or importing them directly from Google Drive or Dropbox. You can rearrange the order by dragging the files up or down. Once you’re happy with the order, click the Merge PDFs button and your combined file will be ready to download immediately.

Click the Google Drive button in the upload area. You will be asked to sign in to your Google account and grant permission to view your files. After authorizing, select the PDF files you want and they will appear in the list ready to merge.

Click the Dropbox button in the upload area. Sign in to your Dropbox account if needed and allow access. Then choose the PDF files you want to import. They will be added to the list so you can reorder and merge them.

You only need to sign in to your existing Google or Dropbox account when you choose to import files from those services. No extra account is required on our side, and you can still upload files from your device without logging in to anything.

Yes. After uploading or importing your files, you can drag and drop them to rearrange the order. The final merged PDF will follow exactly the order you set in the list.

There is no fixed limit on the number of files. However, the total size and the memory of your device will determine how many you can merge comfortably. For best results, we recommend keeping the combined size under 100–150 MB, especially on mobile devices.

Not directly. If a PDF is protected with a password, you need to unlock it first before uploading or importing it to this tool. Once the password is removed, you can merge it normally.

No. This tool only combines the pages of your PDFs. It does not recompress or modify the content, so the quality remains exactly the same as the original files.

No. Your files never leave your device. Everything is processed 100% in your browser — including files you import from Google Drive or Dropbox. We cannot see, access, or store your files.

Yes. You can freely mix PDFs that have different page sizes (A4, Letter, legal, etc.) and orientations (portrait or landscape). Each page keeps its original size and orientation in the final merged document.

Yes. The tool works on modern mobile browsers (Chrome, Safari, Firefox, and Edge) on both Android and iOS. For very large files or many documents, a computer usually gives faster and more stable results.

In most cases, the merged file size is very close to the sum of the original files. Sometimes it can be slightly larger because of how PDF structure and metadata are handled when combining documents. This is normal and does not affect quality.
