Merge PDF Files — Offline
Drop two or more PDFs (plus images or documents if you like) onto MiniMax Converter, reorder every page in a visual organiser, then combine them into a single PDF. You can rotate or drop individual pages along the way. Runs locally — no upload, no file-size limit, no watermark.
How to use it
- Drop two or more PDF files onto the window (images and documents are welcome too — they get rendered to PDF pages automatically).
- Choose Merge to load every page as a thumbnail into the visual organiser.
- Drag thumbnails to reorder, rotate any page, and delete pages you don't want.
- Click to combine into one PDF and save it to your chosen folder.
What you get
Merging PDFs is lossless — pages from existing PDFs are copied through byte-for-byte, so text stays selectable, vectors stay sharp, and nothing is re-compressed. The visual organiser shows a thumbnail of every page so you can drag to reorder, rotate, and delete before you commit. The result is one clean PDF in the order you arranged.
Mix PDFs, images, and documents
You don't have to feed it only PDFs. Drop JPEGs, PNGs, or HEIC photos and they're rendered to full pages; drop a DOCX, ODT, or spreadsheet and LibreOffice converts it to PDF pages first. Everything lands in the same organiser, so you can interleave a scanned image between two report pages or append a cover photo. Optional auto-straighten and searchable-OCR output are available for scanned pages.
Why offline?
Online PDF mergers cap file sizes (often 100 MB or a handful of files), require uploading every document to a stranger's server, and frequently stamp a watermark or paywall the reorder feature. Local merging handles any number of files at any size, runs at SSD speed, adds no watermark, and your documents — contracts, invoices, medical records — never leave your machine.
Questions and answers
Can I reorder the pages before merging?
Yes. Every page is shown as a thumbnail in a visual organiser, and you drag thumbnails into whatever order you want. You can also rotate or delete individual pages before combining.
Does merging reduce quality or re-compress the PDFs?
No. Merging existing PDF pages is lossless — they're copied through unchanged, so text stays selectable and images aren't re-encoded. Quality only changes if you add an image or document, which has to be rendered to a page first.
Can I mix images and Word documents in with the PDFs?
Yes. Drop JPEG, PNG, or HEIC images and they become full pages; drop DOCX, ODT, or other documents and they're converted to PDF pages automatically. All pages then appear together in the organiser.
Is there a limit on how many PDFs or how large they can be?
No file-count or file-size cap — it's limited only by your disk. Because everything runs locally, there's no upload step and nothing is sent to a server.
