Merge PDFs online, free

Drop two or more PDFs, set the order and download a single file. No account, no watermark, files are deleted after every request.

Files

Drag PDFs or documents here, or click to choose

PDF password (only if a file is locked)

With the password entered, the file is unlocked and processed in a single step. Without it, a locked file is rejected.

Operation

Without an account you can merge, split, compress, rotate and convert PNG/JPG to PDF, with a daily limit. The other tools need an account.

Choose a file .html or .htm. It is laid out on A4 pages with text, tables and simple styles. Scripts do not run, and remote images are not downloaded, so images are included as URIs data:.

Choose a Word, Excel, PowerPoint or RTF file (.doc/.docx/.odt/.rtf, .xls/.xlsx/.ods/.csv, .ppt/.pptx/.odp). The conversion runs LibreOffice on the server; if it is not installed, the request returns 503 with the install command. The layout uses the fonts installed on the server.

Choose a damaged PDF. The file is rebuilt with a clean structure: broken cross-reference tables, truncated tails and other structural damage are repaired, and text and images are preserved. Password fields and annotations survive where the damage allows. Each PDF is repaired separately; nothing else in its content is changed.

Choose exactly two PDFs. The first is A (the original), the second is B (the revised file). The result is a PDF report of the changed text, page by page; images and drawings are not compared. If the files are password-protected, the PDF password field must match both.

Choose a PDF, then drag the cards to reorder them. Check pages to rotate or delete them; pages removed from the grid do not appear in the result. Duplication is disabled in this view.

Choose a PDF to load the page thumbnails.

Pages (e.g. 1-3,7 or all)

Split into

Pages per file

Page ranges, separated by commas (each becomes a file)

Target size per file (MB)

Compression level Target size in MB (optional — leave 0 for a preset) Convert images to grayscale

Pages per sheet Booklet — page order for saddle stitching

The Booklet option ignores the pages-per-sheet choice and lays two pages per sheet in the order a folded booklet requires. Print the result double-sided, flip on the short edge, then fold.

Choose exactly two PDFs. The first is the document; the second is stamped on every page of it, repeating its last page if it has fewer pages.

Place the stamped PDF behind the document text

Files to attach

Extracting multiple files returns a ZIP. Attached files travel inside the PDF without appearing on its pages.

Language Recognition DPI Automatically rotate pages detected as upside down Run OCR on every page, even those that already have text

Adds an invisible text layer so scanned pages become searchable and selectable without changing their appearance. Pages that already contain text are skipped unless you force it.
