Merge PDF

Merge PDF files into a single ordered document

Merging PDFs is one of the most common everyday document tasks — whether you need to bundle an invoice with its receipts, submit a single file for a job application, or consolidate a class report from multiple contributors. The OkFarsi Merge PDF tool lets you upload as many PDF files as you need, drag them into the order you want, and export one clean, combined document in a single click.

Unlike desktop software, there is nothing to install. The tool runs entirely from your browser, and the heavy lifting happens on a secure server that only keeps your files long enough to process the request. There is no watermark, no page limit on the output, no forced account creation, and no monthly quota. The output is a standards-compliant PDF that opens in every reader, including Adobe Acrobat, Foxit, macOS Preview, and every mobile PDF viewer.

Behind the scenes, Merge PDF uses page-level streaming rather than rasterizing your files. That means the text stays selectable, hyperlinks remain clickable, bookmarks are preserved where possible, and image quality never degrades. If your source PDFs already contain embedded fonts — including non-Latin scripts — those fonts travel through to the merged output intact.

Because the merge happens at the page-object level, even very large source files are processed quickly. The tool streams pages directly into the destination PDF instead of re-rendering them, so merging a handful of 100-page reports takes only a few seconds. The final file size is close to the sum of the inputs, with no unnecessary inflation, and you can run it through the Compress PDF tool afterward if you need to slim it down further for email attachments or upload forms.

How to merge PDF files in 4 steps

1. Upload your PDF files

   Click the upload area or drag your PDF files directly onto it. You can add as many files as you need in a single session; there is no forced limit on the number of source documents.

2. Arrange the page order

   Each uploaded file appears as a draggable tile. Reorder them into the sequence you want for the final document. You can remove any file by clicking the delete icon on its tile before merging.

3. Press “Merge PDF”

   Once the order looks correct, click the Merge button. The tool uploads the files to a processing server, streams them into a single PDF, and reports the progress in real time.

4. Download the combined PDF

   When processing finishes, a download button appears. Click it to save the merged file to your device. The server-side copy is deleted automatically shortly after the download.

Common use cases

• Job applications & portfolios

  Combine your CV, cover letter, certificates, and reference letters into one PDF before submitting — most application portals accept a single file only.

• Legal & contract bundles

  Merge signed contract pages, NDAs, and appendices into a single evidence file for archival or court submission.

• Invoices and expense reports

  Attach purchase receipts to an invoice PDF so accounting teams receive one consolidated document per transaction.

• Student reports & theses

  Join chapters written by different team members, plus the cover page and references, into one submission-ready PDF.

Privacy & security

Your files are transferred over HTTPS, processed in an isolated job directory, and removed from the server shortly after the download completes. We do not train any model on your documents, do not share them with third parties, and do not retain copies for analytics. The only database entry we keep is a short anonymous job identifier used to deliver your download link — this identifier does not contain file contents or filenames. If you are merging sensitive material (legal, medical, financial), we still recommend removing it from your local Downloads folder after you have archived the final file.
