Slå Samman PDF-filer Steg för Steg
Quick Answer
För att slå samman PDF:er: öppna PDF Merger, ladda upp flera PDF-filer, ordna dem i önskad ordning och klicka på Merge. Verktyget kombinerar filerna till en PDF med ett WASM-baserat bibliotek. All bearbetning sker lokalt.
Introduction
Sammanslagning av PDF-filer kombinerar flera PDF:er till ett enda dokument. Detta är användbart för att sammanställa rapporter från kapitel, kombinera skannade sidor eller skapa en portfolio från separata dokument. Merge-operationen konkatenerar sidor i den ordning du specificerar.
Step by Step
-
Open the PDF Merger tool
Go to the PDF Merger tool page. The tool processes PDFs locally using a WASM-based PDF library (e.g., pdf-lib), so your files never leave your browser.
-
Upload your PDF files
Click upload or drag-and-drop multiple PDF files onto the tool. You can select multiple files at once. The tool lists each file with its page count and size.
-
Arrange the order
Drag the files to reorder them, or use up/down buttons. The files will be merged in the listed order — the top file becomes the first pages of the output.
-
Merge the PDFs
Click Merge. The tool concatenates the pages from each PDF in order, producing a single combined PDF. This typically takes a few seconds for small to medium files.
-
Download the merged PDF
Click Download to save the merged PDF. The tool shows the total page count and file size. Open the result to verify the order and content are correct.
Examples
Merge three chapter PDFs
Input: chapter1.pdf (5 pages), chapter2.pdf (8 pages), chapter3.pdf (6 pages)
Output: full-report.pdf (19 pages) — chapters in order
Merge scanned pages
Input: page1.pdf, page2.pdf, page3.pdf (1 page each)
Output: document.pdf (3 pages) — pages in order
Common Problems
- Wrong order —always verify the file order before merging. Drag to reorder if needed.
- Different page sizes —merging PDFs with different page sizes (e.g., A4 and Letter) produces a mixed-size document. This is usually fine but may look inconsistent.
- Encrypted PDFs cannot be merged —decrypt each PDF first (remove passwords) before merging.
- Large output files —merging many large PDFs can produce a very large output. Compress the result if needed.
Tips
- Arrange files in the correct order before merging —the top file in the list becomes the first pages.
- If you only need specific pages from a PDF, split it first, then merge the desired pages.
- Merge related documents into one for easier sharing —e.g., combine a cover letter, resume, and references into a single application PDF.
- Use our PDF Merger for private, browser-based processing —your files never leave your device.
