How do I convert PDF pages to BMP images?

Upload the PDF file and the converter renders each page as a separate BMP file. By default each page becomes its own image; the result is bundled as a ZIP archive ready to download.

What DPI does the BMP render at?

Default 150 DPI (good for screen viewing and most print). Advanced options expose 72 (web thumbnail), 150 (default), 300 (print quality), 600 (high-quality archival). Higher DPI = sharper images but larger BMP files.

Can I extract just specific pages of PDF as BMP?

Yes — the page-range option accepts inputs like `1-5`, `1,3,5`, or `all` to pick which pages of the PDF get rendered to BMP. Useful when only a chapter or appendix of a long PDF is needed.

Will the BMP preserve PDF text searchability?

No — rasterizing PDF to BMP turns text into pixels. If you need searchable output, keep the PDF as a PDF and use a text-extraction tool instead. Image output (BMP) is for visual display or further image processing.

What about transparent backgrounds in the BMP?

PNG BMP preserves the PDF page background as transparent if the source page has no fill (rare). JPG BMP cannot store transparency — pages render onto a white background. For transparent output target PNG, TIFF, or WebP.

How long does PDF to BMP take for a 100-page document?

About 30-90 seconds for a 100-page PDF → BMP at 150 DPI. Higher DPI doubles or triples the time. Premium users get more parallel workers — 100 pages typically renders in under 30 seconds for them.

What is the file size of a typical BMP page?

A 150-DPI BMP of an A4 page is 200-800 KB (PNG) or 50-150 KB (JPG quality 85). Multiply by page count to size the ZIP — a 100-page PDF to PNG bundle is typically 30-80 MB.

Can I merge all PDF pages into one tall BMP image?

Not in the basic flow — each page becomes its own BMP. To produce a single stitched image, download the ZIP, then use /image-merge/ to vertically concatenate the per-page BMP files.

Is my PDF private during BMP conversion?

Yes — same privacy model: isolated workers, automatic deletion within minutes, no human review.

Will images embedded in the PDF appear correctly in the BMP?

Yes — embedded JPGs, PNGs, and inline graphics inside the PDF are rendered into the BMP at the page DPI. The page renderer treats them like every other page element.

Can I convert just the first page of a PDF as a BMP thumbnail?

Yes — set the page-range option to `1` and the converter produces a single BMP file (not a ZIP). Useful for generating cover thumbnails for a PDF library.

Why does my BMP look pixelated when zoomed in?

You're rasterizing vector content into pixels — zoom amplifies the rasterization. If you need infinite-zoom output, target SVG (where the PDF contains vectors); for sharper rasters, bump DPI to 300 or 600 in advanced options.
