One BMP becomes one PDF page
Each BMP you add becomes one page in a new PDF. The order shown above is the final page order, so a five-image batch produces a five-page PDF unless you remove an image before conversion.
The browser first decodes the BMP as a raster image, draws that image to a canvas, converts the canvas result to PNG data, and embeds that raster image into the PDF. The converter is therefore creating PDF pages from the visible bitmap rather than preserving the original BMP file as an attachment.
BMP has several historical variants. Common browser-decodable BMP files should work, but an unusual compression or bitmap variant can fail at the browser decoding step. When that happens, the tool reports the affected filename instead of producing a blank PDF page.
Scales the image as large as possible inside the selected margins while preserving its aspect ratio. Nothing is cropped, so unused page space may remain.
Preserves aspect ratio but scales until the entire content area is covered. Anything extending past the margin box is clipped, so the image can lose content at two edges.
Forces the image to exactly match the available width and height. Nothing is cropped, but the image can look distorted because its original aspect ratio is not preserved.
A BMP has pixel dimensions such as 1600 x 1200. A PDF page has a physical page size such as A4 or Letter. This tool scales the raster image to the selected PDF page geometry; it does not infer a print size from BMP metadata or promise a particular effective PPI.
If print sharpness matters, the important question is how many source pixels are being spread across the final physical page area. Enlarging a small BMP can make it look soft even though the PDF itself is valid.
Auto orientation is decided independently for each image: landscape-shaped BMPs receive landscape pages, while portrait-shaped BMPs receive portrait pages. Choosing Portrait or Landscape forces the same orientation for every page in the batch.
This matters because the PDF contains a newly encoded raster representation. File size may be smaller or larger than the original BMP collection depending on the images and resulting PNG compression; this tool is not advertised as a dedicated PDF compressor.
Yes. One selected image produces one page, and the on-screen image order controls the final PDF page order.
The browser must be able to decode the bitmap before the PDF can be created. Damaged files and less commonly supported BMP variants can fail that decoding step.
No. Fit preserves the full image and its aspect ratio. If the image and page shapes differ, background space remains around two sides.
Fill enlarges the image until it covers the usable area inside your margins. Overflow is clipped at that margin box, which can remove content from the top and bottom or from the left and right.
The decoded raster keeps its source pixel dimensions before placement, but the image is then scaled to the PDF page. The tool does not guarantee a particular print PPI.
If the browser decodes transparency from the source BMP, the intermediate PNG can retain it and the selected PDF background color can show through. Support depends on how that BMP variant is decoded.
No upload request is made by this component. It reads the selected browser File objects locally, performs the raster conversion in the browser, and creates the PDF there.
BMPs are raster images, and the generated PDF embeds raster image data for every page. The output size depends on image dimensions and PNG encoding, not only on the source BMP file sizes.
