Why Convert BMP to PDF

BMP is a high-quality bitmap image format, but its file size can be large and inconvenient to share. Converting to PDF helps reduce file size while preserving image quality and makes it easier to manage as a document.

PDFs display consistently across various devices and programs, offering strong compatibility. Converting BMP images to PDF makes printing, emailing, archiving, and other use cases much more convenient.

PDFNavi’s BMP → PDF conversion tool can be used directly on the web without installing any additional programs, allowing you to convert images quickly and safely.

Guide to Optimizing Page Settings Before Conversion

BMP files are often uncompressed, high-resolution images, so page settings matter when converting to PDF. Before clicking the convert button, we recommend checking the 'Page Settings' options at the bottom of the preview screen. If your image doesn’t match A4 paper size, you can set margins to 'Narrow' or 'None' to make the image fill the page more fully.

Also, if you have a mix of landscape and portrait images, you can unify the page orientation or use auto mode to improve readability. These pre-settings are an efficient way to reduce extra edits after conversion.

  • If printing is the main purpose, it’s best to set the page size to the standard A4 and leave appropriate margins.
  • If you have many wide images like screenshots, set the page orientation to 'Landscape' so images won’t be cut off.
  • Using margin options helps minimize unnecessary blank space around images and creates a cleaner PDF document.

Using Multi-Select and Order Sorting Features

When working with multiple BMP files, the most useful features are 'drag and drop' and 'multi-select'. You can drag uploaded image thumbnails into the order you want, and the PDF pages will be created in that same order.

If you need to edit several images at once, drag to select a range or click while holding Ctrl (or Shift) to select multiple files. Selected images can be deleted in bulk or rotated to the right in one action, reducing work time.

  • Use the drag-box selection feature to quickly select multiple adjacent images.
  • If a file was uploaded by mistake, select it and press the delete button to remove it from the list.
  • If image orientations differ, use the bulk rotate feature after multi-select to easily unify the direction of all pages.

Understanding the ‘Merge into One PDF’ Option

This tool offers two output methods depending on your goal. By default, the ‘Merge all images into one PDF’ option combines all uploaded BMP images in order into a single PDF document. This is useful when you need a continuous document such as a report or portfolio.

If you want to convert each BMP file into an individual PDF, turn off the merge option. When the conversion is complete, the PDFs are downloaded as a compressed ZIP file. This is the right choice when you only need simple format conversion.

  • For documentation and sharing: enable 'Merge into one PDF' (creates a single file)
  • For separate storage and archiving: disable 'Merge into one PDF' (creates separate files)

BMP File Characteristics and Conversion Efficiency

BMP (bitmap) preserves quality without loss, but file sizes are typically very large. Converting to PDF lets you manage images more efficiently in a document format while keeping image quality as high as possible. PDF also maintains the same layout across many devices and operating systems, which is beneficial for compatibility.

If the converted PDF file is still large, consider using the PDF compression tool provided after conversion. You can keep the high-quality characteristics of the original BMP while optimizing the file size for easier sharing and storage.

  • Because high-resolution BMP originals can be large, the converted PDF may also be large, which is a normal result of preserving quality.
  • If attaching via email is difficult, you can reduce the size by using PDFNavi’s 'PDF Compress' feature.

Frequently Asked Questions (FAQ)

Is there a limit to how many BMP files I can upload?+

No. PDFNavi is provided for free without limits on file count or size, so you can upload and convert large batches of BMP files at once.

Does image quality decrease during conversion?+

The PDF conversion process is designed to preserve the original BMP resolution as much as possible. You can use it with confidence, as it converts to a document format without noticeable visual degradation.

How is the security of my uploaded files maintained?+

All files are transmitted via a secure connection (SSL), and after the conversion is complete, they are automatically and permanently deleted from the server after a certain period of time. Your documents are protected safely.

Will a watermark appear on the converted PDF?+

No. Even in the free version, no watermark is inserted. You can generate a clean PDF document and use it freely.

It was converted in the wrong order. Can I fix it?+

You need to change the order by dragging images during the preview step before converting. If you’ve already finished converting, upload again or use a PDF editing tool to adjust the page order.
