BMP to PDF
Convert BMP images (the uncompressed Windows bitmap format, often from old scanners or Paint) into a single PDF.
How it works
- Handles large, uncompressed BMP files efficiently.
- Batch multiple BMPs into one ordered PDF.
Private by design
The file never leaves your device — everything runs inside your browser tab using JavaScript PDF libraries, with nothing uploaded to any server. That also means there's no per-day limit on how many files you process, since nothing is metered on a server.
Good to know
A larger PDF is handled a page at a time internally, so it takes a little longer rather than failing outright — closing other heavy browser tabs helps if the device has limited RAM.
Frequently asked questions
Why are BMP files so much bigger than JPG?
BMP stores every pixel uncompressed, so a photo-sized BMP can be 5-10× the size of an equivalent JPG.
Is there a sign-up or a watermark?
No — no account needed and the output file carries no watermark.
Does it work on mobile?
Yes, it runs in any modern mobile browser on Android or iPhone, not just on desktop.
Is my file kept or deleted after processing?
Neither — it's never uploaded in the first place, so there's nothing stored on any server to delete.
