Convert BMP to PDF

About this tool

Convert supported uncompressed BMP images into actual PDF downloads.

Supported input

BMP

Output format

PDF

Batch size

Up to 5 files; format and combined limits below still apply.

How it works

1. Add Uncompressed BMP files in Input. Review each thumbnail and its validation status.
2. Order the selected images, choose a page size and embedded-JPG quality, then create one PDF.
3. Create the selected files. Compare original and result, then download an individual file or ZIP. Changing settings marks older results out of date.

Supported files and limits

Up to 5 files, 10 MiB each and 25 MiB combined. Each image must fit within 8192 pixels per side and 20 million pixels; a batch is limited to 40 million input pixels. Output is limited to 20 MiB per file and 50 MiB combined. One isolated image job runs at a time, with a 30-second timeout and cancellation.

A practical example

Place supported BMP scans or pictures into PDF pages for sharing. Check their order and legibility in an independent PDF viewer.

Troubleshooting this tool

Only standard uncompressed 24-bit BMP inputs are supported. Picture pages do not become searchable text, and JPG embedding can change sharp line detail.

BMP input requires uncompressed 24-bit RGB with a standard 40-byte DIB header, no palette/profile and exact padded row bytes. Both top-down and bottom-up rows are supported. Other BMP variants are rejected.

Check the actual export

One image per PDF page, in Input order. Embedded images use JPG encoding; transparency is flattened. No OCR or searchable text is created. Only the input variants listed below are supported. Pixel dimensions are preserved; source resolution and descriptive metadata are not retained. Inspect downloaded dimensions, transparency and fine edges before replacing an original. Browser encoders differ; a quality setting is not a universal fidelity score, and file size may increase.

Files stay in your browser

No file bytes are uploaded. Ordinary work stays in memory. Choosing a “Continue” action saves that result in this browser for up to 30 minutes, so another compatible working tool can use the actual output. Saved workflows are limited to 50 MiB and 20 files; clear them in Output. Expired entries are removed on later tool visits. Clearing references is not a secure-erasure promise.

If a file fails

Check its actual format and the restrictions above. Renaming a file does not convert it. A failed file does not erase successful batch results. If processing times out, cancel and try fewer or smaller files. A current browser with worker canvas support is required.

Before you use the download

• Open every PDF page and confirm image order, paper fit and readable detail.
• Picture pages do not contain recognized text; check the selected transparency background and embedded-image quality.

Tools that accept this output

These links use this tool's default output format, subject to each next tool's supported variants and limits. If you change the export format, use Continue in Output to see compatible actions for the actual result. Opening a link below starts another tool without transferring a file.

• Merge PDF files — Join simple PDF documents in your chosen file order, without rasterizing their pages.
• Rotate PDF pages — Rotate all or selected pages of a simple PDF by 90, 180 or 270 degrees clockwise.
• Split PDF into parts — Split a simple PDF into equal-sized page groups and download the actual PDF parts in a ZIP.
