Coolmuster JPG to PDF Converter: Batch Images into PDFs
Coolmuster JPG to PDF Converter is a $15.95-a-year Windows program that turns JPG, PNG, TIF and BMP images into PDFs, one PDF per image or all merged into one.
You've got a stack of phone photos of signed pages, and the form wants one PDF. The phone can do it one picture at a time. On a PC with dozens of images, a batch tool is less tedious.

Before you buy
For one or two images, Windows already does this free. Printing a picture to Microsoft Print to PDF gives you a PDF with no extra software. This tool earns its fee when you have many images and want consistent page sizes, margins or one merged document. OCR isn't listed, so scans stay as pictures with no searchable text.

Features
Several image formats
Coolmuster JPG to PDF Converter accepts JPG, JPEG, PNG, TIF and BMP images, and a batch can mix them.
The start window, which accepts images with Add File, Add Folder or drag and drop.
Merge into one PDF
JPG to PDF Converter's Merge into one file option combines all selected images into a single PDF, handy for turning page photos into one document.
Page size and margins
JPG to PDF Converter offers a page type such as A4 or a custom width and height, along with four adjustable margins in millimetres.
Batch conversion
JPG to PDF Converter converts everything you've selected in one run, and a progress bar shows how far along it is before you open the output folder.
Benefits
- Dozens of pictures become one document in a single run.
- Consistent page sizes and margins make a tidier PDF than ad hoc printing.
- Images stay on your PC.
Real-World Uses
- Combining photographed signed pages into one PDF to send back.
- Turning a folder of scanned receipts into one expense document.
- Making a simple photo portfolio as a PDF.
- Converting old TIF scans into a format anyone can open.
Who It's For, and Who Should Skip It
It's for people who convert many images to PDF on a regular basis and want page options.
Skip it if you only do this occasionally, since Windows' Print to PDF and phone scanning apps are free. If you also need Word, ePub or HTML to PDF, PDF Creator Pro at $29.95 includes this function. There's no Mac version of this one.
Usage Guide
- Install JPG to PDF Converter from the Download Free Trial button and launch it.
- Click Add File or Add Folder, or drag images into the window.
- Tick the images you want and set the page size and margins.
- Choose an output folder and tick Merge into one file if you want one PDF.
- Click Start, then Show in folder or Open Folder to see the result.
Where It Falls Short
- OCR isn't listed, so the result isn't searchable text.
- Windows only.
- Free options cover occasional use.
- One buyer reports needing some time to find the best settings.
What Users Say
Coolmuster's site shows customer reviews, but it also runs a "Win Free Coolmuster License Code" offer for writing one, and many entries are short and unspecific. Treat them as a sign of what buyers care about, not as independent testing.

Independent coverage
Softpedia's editor review describes a simple converter with batch processing and a clear file list.
Buyers like the batch handling and the image quality. The only real complaints are a slow download for one person and a learning curve for settings for another.
