    About PDF to BMP

    When is it useful? PDF to BMP saves each page of a PDF as a BMP bitmap picture. BMP is still needed by some older Windows programs, embroidery and engraving machines, label printers and office software that cannot open PDF, PNG or JPG files.

    Good to know: BMP files are not compressed, so they are much bigger than JPG or PNG — one A4 page at 300 DPI is about 26 MB. Choose Screen (96 DPI) for viewing, Standard (150 DPI) for most jobs, and High (300 DPI) only when you need print quality. Every page becomes its own image, and all pages are downloaded together in one ZIP file, or one by one from the file list.

    Tips for Better Results

    • Start with 150 DPI; choose 300 DPI only if the receiving program asks for print quality.
    • If the program also accepts PNG, use PDF to PNG instead — same sharpness, much smaller files.
    • Unzip the downloaded file to get one BMP image per page.

    PDF to BMP: a complete guide

    What BMP is

    BMP (bitmap) is one of the oldest Windows picture formats. It stores every pixel without compression, so it is simple for software and machines to read. That is why some older Windows programs, embroidery and engraving machines, LED and label printers, and industrial equipment still accept only BMP files.

    What happens when you convert

    Each PDF page is drawn at the resolution you choose and saved as a 24-bit colour BMP. Screen (96 DPI) gives about 794 × 1123 pixels for an A4 page, Standard (150 DPI) about 1240 × 1754, and High (300 DPI) about 2480 × 3508. Pages are named by number and downloaded together in one ZIP, or one by one from the file list.

    Size matters with BMP

    Because BMP is uncompressed, the file size depends only on the pixel count: about 2.7 MB per A4 page at 96 DPI, 6.5 MB at 150 DPI and 26 MB at 300 DPI. Use the lowest resolution your machine or program needs.

    Common problems and how to fix them

    The machine needs a specific size, such as 640 × 480 pixels: open the BMP in Windows Paint, use Resize, and save it again as BMP. The machine wants black-and-white (1-bit) BMP: open the file in Paint and save as Monochrome Bitmap. The ZIP will not open on the machine: unzip it on a computer first and copy the BMP files.

    Good habits

    Check the machine's manual for its exact BMP requirements, convert only the pages you need, and keep the PDF as the original.
