How to Convert Image to PDF on Windows (No Software Installation Required)
Windows doesn't include a straightforward way to convert images to PDF. The Photos app can print images but doesn't offer a clean PDF export. Microsoft Paint and the built-in image viewer have no PDF option at all. Most search results will point you to paid tools like Adobe Acrobat or various sketchy freeware converters. The simplest free solution is LazyPDF in your browser. It works in Microsoft Edge (pre-installed on every Windows PC) and Chrome. Your images are processed entirely on your computer using pdf-lib running in JavaScript — no files are uploaded, no account is needed, and nothing is installed on Windows. This guide covers the full process on Windows, including how to combine multiple images, handle different formats, and find your PDF in File Explorer.
Convert Image to PDF on Windows Using Edge or Chrome
Both Edge and Chrome on Windows support the web standards LazyPDF uses to read images from your disk and create PDFs locally. Edge is already on your Windows PC — you don't need to install anything. The tool supports JPEG, PNG, WebP, BMP, and other common image formats. You can convert a single image or combine many images into a multi-page PDF. The conversion typically completes in a few seconds regardless of which browser you use.
- 1Open Microsoft Edge or Chrome on your Windows PC and go to lazy-pdf.com/en/image-to-pdf
- 2Click the upload area or drag image files from File Explorer directly into the browser window
- 3Selected images appear as page previews — drag them to set the page order in your PDF
- 4Click 'Convert to PDF' — pdf-lib generates the PDF locally in your browser
- 5Click Download — Edge or Chrome saves the PDF to your Downloads folder (C:\Users\YourName\Downloads)
Drag Images From File Explorer Into Chrome or Edge
The most efficient way to work on Windows is to position your browser window and File Explorer side by side. In File Explorer, navigate to your images folder. Hold Ctrl and click to select multiple image files, or Shift-click to select a range. Then drag the selected files into the LazyPDF upload zone in your browser. Windows immediately passes the files to the browser, which loads them as page previews. This workflow eliminates the need to navigate through a file picker dialog and is especially fast when working with images already organized in a folder. Right-click the File Explorer window title bar and choose 'Snap to left' or 'Snap to right' to tile windows quickly.
Windows Native Alternatives: Print to PDF and Microsoft Photos
Windows does have a 'Microsoft Print to PDF' virtual printer that creates PDFs from anything you can print. In the Photos app, open an image and press Ctrl+P, then select 'Microsoft Print to PDF' as the printer and click Print. This works for single images but is awkward for multiple images — you'd need to repeat the process for each image or use a print queue trick. Microsoft Photos also has a basic PDF export through the Print dialog. These native methods work in a pinch, but they don't let you combine multiple images into one PDF cleanly, and the page sizing options are limited compared to LazyPDF.
Combining Multiple Images Into One PDF on Windows
This is where LazyPDF shines on Windows compared to native options. Select all the images you want to combine — screenshots, scanned pages, photos — drag them all into LazyPDF at once, and convert. Each image becomes a separate page in the PDF, in the order you arranged them. Need to fix the order? Drag the page thumbnails before clicking Convert. This is far simpler than the workarounds required with Windows native tools, where combining multiple images into one PDF typically requires Microsoft Word, LibreOffice, or PowerPoint as an intermediary — all of which change formatting and require multiple save steps.
Privacy and Safety on Windows
Windows users face a particular risk when searching for 'free image to PDF converter' — many results lead to installer bundles that include adware, browser hijackers, or worse. LazyPDF eliminates this risk entirely by running in your browser. There is no installer, no .exe file, no Windows Registry changes, and no background processes. Your images are never sent over the internet. This makes LazyPDF safe even for sensitive documents like scanned ID cards, financial statements, or medical records. After you close the browser tab, no data about your files remains anywhere on the web.
Frequently Asked Questions
How do I convert a JPG to PDF in Windows 11 without installing software?
Open Microsoft Edge (pre-installed on Windows 11), go to lazy-pdf.com/en/image-to-pdf, and drag your JPG file into the upload zone. Click Convert to PDF, then Download. Your PDF is saved to C:\Users\[YourName]\Downloads. The whole process takes under 30 seconds and requires no installations, no Microsoft account, and no additional software. It also works in Windows 10 using Edge or Chrome.
Can I combine PNG screenshots into one PDF on Windows?
Yes. LazyPDF accepts PNG files and lets you combine multiple screenshots into a single multi-page PDF. Hold Ctrl while clicking multiple PNG files in File Explorer, then drag them into the LazyPDF tool in your browser. Arrange the page order by dragging the previews, then click Convert. This is useful for creating documentation PDFs from screenshots, combining snipped images into a report, or archiving a multi-step process captured with the Snipping Tool.
Does the image-to-PDF converter work in Microsoft Edge on Windows?
Yes, LazyPDF works perfectly in Microsoft Edge on Windows 10 and 11. Edge is based on the same Chromium engine as Google Chrome, so all the same web APIs are available. Since Edge comes pre-installed on every Windows PC, you can use LazyPDF immediately without downloading any additional browser. The tool also works in Firefox on Windows if you prefer that browser — the PDF creation happens client-side regardless of which modern browser you use.
