Up to 200 files
Updated
The tool creates a new empty PDF, then copies every page from each of your files into it in the order of the list, and saves the result as merged.pdf.
You choose only one thing: the order of the files. There are no options for page ranges, compression or bookmarks. Pages are copied as they are, so text stays selectable and vector graphics stay sharp; nothing is rasterised.
You can add up to 200 PDFs, each up to 200 MB, and only PDF files are accepted.
Because everything happens in your browser tab, very large or very many files depend on your device's memory. If a merge of hundreds of megabytes stalls, split the job into two smaller merges and merge those results. The output is a single file. Bookmarks, outlines and interactive form behaviour from the source files are not reliably preserved, since pages are copied into a new document.
Merge PDF fits when you already have finished PDFs and just need them back to back.
• Joining a scanned contract, its signed cover page and an invoice into one file to email. • Stitching monthly statements into a single yearly document. • Assembling chapters exported separately from a word processor. If you only need pages 3 to 7 of a longer document, use Split PDF instead. If your source material is images rather than PDFs, JPG to PDF builds a PDF from them, and Combine Files to PDF handles mixed inputs. If the merged pages are in the wrong sequence, Reorder PDF Pages fixes that afterwards.
The merged file is not compressed, so its size is roughly the sum of the inputs.
Expect the output to be about as large as all inputs added together. If the merged file is too heavy, Compress PDF can either keep text selectable with a light rewrite or redraw pages as compressed images for larger savings on scan-heavy files. There is no page-level preview of the combined result before download, so open merged.pdf once to confirm the order.
Combining PDFs is easy; getting a clean result takes a little planning. Ordering, mixed page sizes, links and forms, and file size all matter.
Every PDF tool on Synthixx grouped by job, with one honest sentence on each, its main limitation, and a clear list of what the site does not offer.
A straight answer, using iLovePDF's own published statements: what it does with your file, how long it keeps it, the five-year exception, and when to use something else.
No. This tool always copies every page of every file. To use only part of a document, first cut it down with Split PDF or Extract PDF Pages, then merge the results.
The order of the file list, top to bottom. Pages inside each file keep their original order. Drag the entries in the list to change it before you click Merge.
No. The merge runs in your browser using a PDF library, and the files are not sent to a server for this job.
Do not count on it. The tool copies page content into a fresh document, so document-level features such as bookmarks and outlines are not carried over. Check the result if you rely on them.
The tool opens files while ignoring the encryption flag, so some restricted PDFs may merge, but this site has no tool to add or remove passwords. If a file fails to load, it cannot be merged here.
