How to convert PBM to PDF

  1. Add your PBM images

    Drop PBM files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.

  2. PDF is already chosen

    Press Convert. Open Options first if you want to change the defaults. The work happens in this tab.

  3. Download

    Save the PDF, or download everything as one ZIP if you converted several files.

Why ToAny

  • Private by construction

    The PBM to PDF converter is part of this page and runs inside your browser. Your images are never sent to ToAny or to anyone else.

  • No upload, no queue

    Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.

  • Free, without an account

    No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.

PBM to PDF: what to expect

PBM holds only black and white and few everyday apps open it. PDF looks the same on every device and keeps several pages in one file. PBM is at home in black-and-white line art and scanned text in command-line tools; PDF is the usual choice for documents that must look the same everywhere, and printing.

Add several files and you can also combine them into a single PDF. The defaults suit most files. Under Options you can choose the page size.

PBM holds only black and white, so the result has no greys. Each picture becomes one page. The page can match the picture's own size or be A4 or US Letter; on paper the sheet turns to suit the picture, which is shrunk to fit inside the margins and never enlarged.

PBM vs PDF

PBM

PBM image

PBM is the black-and-white member of the Netpbm family: every pixel is a single bit, either on or off, with no greys. It suits fax-like scans and bitmaps and was the format other Unix tools used to hand pictures to each other.

Opens in GIMP, ImageMagick, IrfanView and Unix graphics tools; not browsers

PDF

PDF document

PDF fixes a document's layout so it looks identical on every screen and printer. That makes it the default for forms, invoices and anything sent to print, and also what makes it awkward to edit.

Questions

Are my images uploaded anywhere?

No. The PBM to PDF conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.

Is anything lost when converting PBM to PDF?

No visible change: the image is placed on a PDF page at its full resolution.

Can I convert several PBM files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP. You can also merge them into a single PDF.

How do I convert PBM to PDF on Windows, Mac, iPhone or Android?

The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the PBM file, press Convert and save the PDF. There is nothing to install.

Is there a file size limit?

Because nothing is uploaded, the practical limit is your device's memory. Very large files can fail on phones with little free memory; a computer copes better.
