Frequently Asked Questions

What is a BMP file and why convert a PDF to BMP?

BMP (Bitmap) is a lossless, uncompressed raster image format originally developed by Microsoft for Windows. Converting a PDF to BMP is useful when you need pixel-perfect copies of each page for legacy software, embroidery and CNC machines, scientific imaging, archival workflows, or any app that doesn't read PDFs but accepts plain bitmaps.

How is the BMP resolution and quality determined?

Each PDF page is rendered at a 2× scale relative to its declared size, which produces sharp, high-resolution bitmaps suitable for printing and detailed on-screen viewing. Because BMP is uncompressed, there is no JPEG-style quality loss — what you see is exactly what is stored.

Are my PDF and BMP files uploaded to your servers?

No. The whole conversion runs locally in your browser using PDF.js and the HTML5 canvas API. Your original PDF and the resulting BMP images never leave your device, so the tool is safe for confidential and sensitive documents.

Why is the output a ZIP archive instead of a single image?

A PDF can contain many pages, while BMP is a single-image format. To keep the download tidy, we package every page as its own .bmp file (page_1.bmp, page_2.bmp, …) inside one ZIP archive that you can download in a single click and unpack with any unzip tool.

Is there a page limit, file size cap, or daily usage limit?

No artificial limits. Because the conversion runs in your browser, the only real constraint is your device's memory. Modern laptops can comfortably convert PDFs with hundreds of pages, and you can run the tool as many times as you want — it's completely free.
