Bitmap (BMP) files are traditionally very large because they contain uncompressed pixel data. If you need to share a BMP file, converting it to a PDF wrapper is the smartest choice for ensuring no pixel data gets accidentally compressed by messenger apps.

Frequently Asked Questions
Can I convert multiple images to one PDF at once?+
Yes. Select multiple images in the file picker, or drag and drop several files. You can reorder them before generating the final PDF document.
Will my original image quality be preserved in the PDF?+
By default, we preserve full quality. An optional quality slider lets you trade quality for smaller file sizes. The original files are never modified.
Is there a file size limit for this converter?+
No server limit. Since processing happens entirely in your browser, the practical limit depends on your device RAM — typically 50MB or more per image on modern devices.
Does the PDF converter work without internet?+
Once the page loads, yes. The conversion engine runs entirely inside your browser tab. You can go offline and convert files without any internet connection.
