    Merge Scanned Documents

    When scanning multi-page documents, each page often becomes a separate file. Merge all scanned pages into one cohesive PDF that represents the original document.

    Select two or more PDFs to merge

    Best Practices

    • Scan all pages at the same DPI (300 DPI recommended)
    • Ensure consistent page orientation
    • Remove blank or duplicate scans before merging
    • Name pages sequentially before uploading

    Scanning Best Practices

    Use 300 DPI for documents with text, 150 DPI for simple forms. Scan in color only if the original contains important color information; grayscale produces smaller files.

    Post-Merge Compression

    Scanned documents are typically image-heavy and large. After merging, use the Compress PDF tool to significantly reduce file size — often by 50-70%.

    After Merging

    If your merged PDF is too large, compress it. Need to extract pages later? Use the Split PDF tool.

    Frequently Asked Questions

    How many PDFs can I merge?
    There's no hard limit. You can merge dozens of PDFs at once. Very large batches (100+ files) may be slow on older devices.
    Does merging reduce quality?
    No. Merging copies pages exactly as they are - no re-encoding or compression. The output quality is identical to the input.
    Can I reorder files before merging?
    Yes. Use the up/down arrows to arrange files in the order you want them in the final document.
    Is this tool free?
    Completely free. No signup, no watermarks, no limits. All processing happens in your browser.
