How to Merge PDF Files Online
Combine multiple PDFs into one document with no watermarks, no quality loss, and no cost.
Everything runs in your browser using client-side processing. No software to install, no account required, and your files never leave your device.
Merge PDF Files in 3 Steps
Upload Your PDF Files
Drag your PDFs onto the upload area or click to browse. You can select multiple files at once. Each file can be up to 100MB. If a file is password protected or corrupted, it will be flagged with an error and skipped automatically so the rest can still be merged.
Arrange the Order
Your files appear in a list with their names and sizes. Use the up and down arrow buttons on each file to move it into the position you want. If you need to add more files without starting over, click the Add More PDFs button. You can also remove any individual file with the X button, or clear the entire selection to start fresh.
Merge and Download
Once you have at least two files, the Merge button becomes active and shows how many PDFs you are combining. Click it and a live progress bar shows the work happening. When it is done, you will see "Merge Complete!" and can download your merged PDF, go back to edit your selection, or start a new task entirely.
