This tool is designed to feel like a simple “upload → adjust → convert” flow. You drop one or many BMP files into the uploader, optionally tweak the PDF layout settings, then hit Convert to PDF. After conversion, you’ll see your result(s) listed with file names and sizes, ready to download.

• 1) Upload BMP files: Drag and drop your images into the upload area (or click to browse). The uploader is built for multiple files, with previews so you can confirm you picked the right images.
• 2) Reorder your pages: If you uploaded more than one BMP, you can sort them so the PDF pages come out in the right sequence (think: “scan_01, scan_02, scan_03” vs. “final cover page” first).
• 3) Rotate when needed: If a scan came in sideways (it happens), rotate the preview before converting. This saves you from re-scanning or editing later.
• 4) Choose page settings: Select your page size (Fit, A4, or US Letter), page orientation (Automatic, Portrait, Landscape), and margin (No Margin, Small Margin, Big Margin).
• 5) Merge pages (optional): Keep Merge images in PDF file enabled to combine multiple BMPs into a single multi-page PDF. Turn it off if you prefer separate PDFs per image.
• 6) Convert & download: Click Convert to PDF, then download the output file(s). If there are multiple outputs, you can also use Download All to grab everything at once.

Page size choices that match real-life printing

Not every BMP is meant for the same destination. Sometimes you’re converting a diagram that should fill the page. Other times you’re turning scanned receipts into a tidy PDF archive. That’s why this converter gives you three practical page size options: Fit (same page size as the image), A4, and US Letter.

Use Fit if you want the PDF to behave like a “container” for the image—minimal scaling, minimal drama. Pick A4 or Letter when the PDF is meant to be printed or combined with other documents that already follow a standard page size.

Automatic, portrait, or landscape orientation

Orientation sounds simple until you have a mixed batch: some BMPs are portrait scans, others are landscape screenshots. The Automatic option is there to reduce manual micromanagement. If you’re preparing a document that must be consistent (for example, a contract appendix that should all be portrait), you can force Portrait or Landscape.

And if you’re dealing with sideways scans, you can rotate the images first in the preview. That way you’re not “fixing” a PDF later with extra steps.

Margin control for clean edges and better readability

Margins are one of those small settings that matter a lot in the final result. Scanned documents often have content close to the edge, and printers can crop that. With No Margin, you keep the image edge-to-edge. With Small Margin or Big Margin, you add breathing room so the PDF looks more “document-like” and prints more safely.

If you’re building a PDF for review—like sending screenshots to a client—small margins can also make annotations and highlights easier to see.

Merge multiple BMP files into one PDF (or keep them separate)

The checkbox Merge images in PDF file is the quiet hero here. When it’s enabled (it is by default), your uploaded BMPs become a single multi-page PDF. That’s perfect for scanned forms, multi-page invoices, or a set of screenshots you want to keep together.

If you’re converting unrelated images, disable merging so each BMP becomes its own PDF output. You’ll still get a neat results table with download buttons, and if there are multiple files, a Download All option makes it painless.

This tool is for normal people with real files. You don’t need a graphics editor. You don’t need a PDF app. You just need your BMPs turned into a shareable format.

• Office admins: Convert scanned BMP receipts into a single PDF for monthly expense reports.
• Students: Bundle hand-drawn notes or whiteboard photos saved as BMP into one PDF for submission.
• Engineers & tech teams: Turn exported BMP diagrams into a PDF that clients can open on any device.
• Support agents: Combine a set of BMP screenshots into one PDF ticket attachment that won’t get blocked by email filters.
• Accountants: Standardize archives by converting BMP scans to A4 PDFs with small margins for printing.
• HR teams: Merge scanned forms into a single multi-page PDF per employee record.
• Legal assistants: Convert evidence images to PDF so they can be paginated, referenced, and printed cleanly.
• Anyone migrating old backups: BMP folders become PDFs that are easier to store, preview, and search in document systems.

Could you do this manually? Sure. But it usually means extra apps, extra steps, and inconsistent results. Here’s a practical comparison that matches what people actually do at work.

Pick “Fit” when quality matters more than standard pages

If you’re converting diagrams, screenshots, or anything where exact proportions matter, start with Fit (Same page size as image). It reduces unexpected scaling and keeps the PDF faithful to the original BMP.

Use A4/Letter when the PDF is meant to be printed or filed

For paperwork, choose A4 (common in many countries) or US Letter (common in the US). Pair that with Small Margin so printers don’t clip edges, and your PDF looks more like a normal document set.

Let “Automatic” orientation handle mixed batches

When you upload a mix of portrait and landscape images, forcing one orientation can lead to awkward empty space or rotated pages. Automatic typically keeps each page readable. If you need consistency for a formal packet, choose portrait or landscape and rotate outliers before conversion.

Order matters—sort files like you mean it

When you’re creating a multi-page PDF, the final document is only as clear as its page order. Put “cover” first, “details” next, and “appendix” last. If your files have messy names, reorder them manually in the uploader until the preview sequence matches the story you want the PDF to tell.

• For clean archives: Use A4/Letter + Small Margin and keep merged PDFs per topic (one PDF per invoice set, one per project, etc.).
• For quick sharing: Use Fit + Automatic orientation and merge screenshots into one PDF so recipients can scroll in order.
