    Combining multiple JPG images into one PDF

    Converting multiple JPG images into a single PDF is one of the most common document workflow tasks — combining scanned document pages, assembling a photo book, creating a multi-page submission from individual screenshots, or packaging multiple receipt photographs into a single expense document. PDFWix Image to PDF handles all these scenarios free in your browser.

    Step-by-step: multiple JPGs to one PDF

    1. Open PDFWix Image to PDF.
    2. Click to upload or drag multiple JPG files at once — you can add them all in one selection.
    3. Arrange page order — drag images up and down to set the correct sequence. This is the most important step. Verify the order before converting.
    4. Choose page size: A4 (standard international), US Letter (American standard), or Fit to image (each page sized exactly to the image dimensions — best for photographs).
    5. Choose orientation: Portrait or Landscape per image, or set a global orientation for all pages.
    6. Click Convert to PDF. Download the single combined PDF.

    Getting the page order right

    Incorrect page order is the most common mistake when combining JPGs to PDF. If you are converting a multi-page scanned document where each page was scanned individually, number the scans as you save them (page-01.jpg, page-02.jpg) so they sort correctly. PDFWix Image to PDF shows image thumbnails in the upload area — verify every page is in the correct sequence before clicking Convert.

    Best page size setting for different use cases

    Scanned documents: Use A4 or Letter depending on the original document size. Photographs: Use Fit to image — this preserves the exact pixel dimensions as the page size, avoiding any scaling. Screenshots: Use Fit to image or A4 landscape for wide screenshots. For compressing the resulting PDF, see our guide on PDFWix Compress PDF. For iPhone users specifically, see converting PNG screenshots to PDF on iPhone.

    Frequently asked questions

    Can I mix JPG and PNG images when combining to PDF?
    Yes. PDFWix Image to PDF accepts JPG, PNG, HEIC and WebP images. You can mix formats in a single conversion — for example, some pages as JPG and others as PNG. All images are embedded in the PDF at their original quality.
    What is the maximum number of JPG images I can combine into one PDF?
    PDFWix Image to PDF supports combining many images — practical limits depend on your device memory. Most devices handle 50–100 images comfortably. For very large batches (200+ images), split into groups, convert each group to PDF, then use PDFWix Merge PDF to combine the resulting PDFs.
    Does combining JPGs into a PDF reduce image quality?
    PDFWix Image to PDF embeds images at their original resolution and quality — no resampling or compression is applied during conversion. The resulting PDF contains the full-quality JPG images. You can optionally compress the PDF afterwards using PDFWix Compress PDF if you need a smaller file size.
