Online PDF Merger review
A focused browser merger for combining and ordering up to 20 PDFs.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Online PDF Merger is a browser-based tool for combining multiple PDF files into one document. It is aimed at users who need a straightforward way to upload PDFs, arrange their order, create a merged file, and download the result without installing desktop software. The free service supports up to 20 PDF files in a single merge job, making it suitable for routine document consolidation and smaller batch workflows.
Pricing is direct: Online PDF Merger is offered free of charge. Its Free plan includes online PDF merging, support for up to 20 PDF files per merge, and file-order arrangement. The core workflow covers uploading files, reordering them with drag-and-drop controls, generating the merged PDF, and downloading it. That focused scope keeps the product relevant for users who need file combination rather than a wider document-editing workspace.
File handling is a notable part of the workflow. Uploaded source files are automatically deleted during processing, and generated files are automatically deleted after 30 minutes. Users can also manually delete generated files before that expiration. These controls suit people who want short-lived processing for individual PDF jobs. The main trade-offs are the 20-file limit and the browser-only format, along with a focus on merging rather than page-level editing. Choose Online PDF Merger for free, occasional PDF combining with drag-and-drop ordering; choose another tool if your work requires broader document editing or larger merge batches.
