Windows has included Microsoft Paint since version 1.0 in 1985, making it the most familiar image tool on the platform across an entire generation of users. Paint can open PNG files and save them as JPEG via File then Save As then JPEG picture. However, Paint uses a fixed internal quality setting with no user-adjustable slider available in the standard interface. On Windows 10 and 11, Paint applies a quality setting in the 85 to 90 percent range by default, which is adequate for general use but not configurable for specific size targets. If you need to hit a specific file size target or match a quality standard set by a CMS, Paint provides no way to control the output precisely. Additionally, Paint does not support batch conversion: each file must be opened, exported, and closed individually, which becomes painful for sets of more than two or three files.
The Windows Photos app, the default image viewer on Windows 10 and 11, similarly lacks meaningful format conversion controls. The Photos app can resize images, apply basic enhancements, and export edited copies, but it does not offer a dedicated export-to-JPEG function with a quality slider visible to the user. The internal export quality is also fixed and undocumented. For users who need to convert PNG to JPG with explicit quality control on Windows without installing additional software from the Microsoft Store or a third party, a browser-based tool is the most practical option. Microsoft Edge, which is pre-installed on all Windows 10 and 11 systems, works fully with FixTools and requires no additional installation, downloads, or permissions.
For power users comfortable with the command line, Windows also supports PowerShell-based image conversion using the System.Drawing assembly which is part of the .NET runtime included by default in Windows. A short PowerShell script can add the System.Drawing.Imaging type, create a Bitmap object from the source PNG, and call Save with a JPEG encoder and an explicit quality parameter between 1 and 100. This approach gives full quality control and can be wrapped in a loop for batch conversion of an entire folder. For most users, however, using FixTools in Edge is significantly faster and requires no scripting knowledge, no understanding of .NET, and no concern about execution policy restrictions on corporate Windows installations.
Third-party Windows applications including IrfanView, FastStone Image Viewer, and XnView all support PNG to JPG conversion with batch processing and quality control. These tools are free for personal use and have been mainstays of the Windows image processing scene for decades, but each one requires a separate download, installation, occasional updates, and some learning curve to navigate the interface. For occasional conversions, the friction of installing a dedicated app is rarely worth the marginal benefit over a browser-based tool. For users who run conversions hundreds of times a week as part of a professional workflow, IrfanView in particular is worth installing for the keyboard-driven batch processor it includes. For everyone else, FixTools in Edge is a faster path to a finished JPG.
Open FixTools in your Windows browser, upload or drag your PNG file, choose JPG output, and download your converted image directly to your Windows Downloads folder.
Step-by-step guide to convert png to jpg on windows:
Open Chrome or Edge on Windows
Visit fixtools.io in your preferred Windows browser and open the Image Format Converter. Microsoft Edge is pre-installed on every Windows 10 and 11 machine, so this step requires no additional software installation if Chrome is not already on the system. The page loads in under a second on most office and home connections, and works fully offline after the first load completes.
Upload your PNG file
Click the upload button to open the Windows file picker, or drag your PNG directly from File Explorer onto the tool. For batches, tile File Explorer and the browser side by side using Windows key plus left or right arrow, then drag selections between the two windows. Hold Ctrl while clicking in File Explorer to select multiple non-contiguous files for batch upload.
Select JPG as output format
Choose JPG from the output format options panel. The format selection persists across uploads in the same session, so subsequent batches default to JPG output without re-selection. JPG and JPEG produce identical files because they are interchangeable file extensions referring to the same underlying image format standard developed by the Joint Photographic Experts Group.
Set your quality preference
Adjust the quality slider to a value between 1 and 100 percent. A setting of 85 to 90 percent is ideal for most images on Windows, balancing file size reduction with visual quality. For technical documentation screenshots that contain a lot of UI text, push the slider to 92 percent or above to keep character edges crisp. For chat-app-bound thumbnails, drop to 80 percent for the smallest practical file size.
Convert and save to Windows
Click Convert to run the encoding step, then download the JPG. The file saves to your Windows Downloads folder by default, located at C:\Users\YourName\Downloads. You can change the default location in your browser settings. In Edge, go to Settings then Downloads to set a different folder, or enable Ask me what to do with each download to choose per file.
Common situations where this approach makes a real difference:
Office worker attaching images to a work ticket
A Windows user takes a PNG screenshot of a software error message and needs to attach it to a Jira ticket where a strict 1 MB file size limit applies per attachment. They drag the PNG onto FixTools in Edge, convert at 90 percent quality, and the resulting 280 KB JPG uploads to the ticket instantly. This entire workflow takes under a minute and requires no software installation on their work computer, which would have needed IT approval and a help desk request that could take days to resolve through corporate change management.
Teacher creating digital learning materials
A teacher on a school Windows PC converts 25 PNG diagram images to JPG before inserting them into a PowerPoint presentation for a class lesson. Converting at 88 percent quality reduces the total image payload from 75 MB to under 10 MB, making the final presentation file small enough to email to students through the school email system and load quickly on classroom projectors over the school Wi-Fi. The diagrams retain enough clarity at the projection size for students at the back of the room to read all the labels and arrows clearly.
Windows user preparing images for eBay listings
A seller listing items on eBay drags a folder of PNG product photos from File Explorer into FixTools in Chrome, converts all 12 photos to JPG at 90 percent quality, and downloads the resulting ZIP archive. The converted JPGs meet eBay image size recommendations and upload quickly from their Windows laptop on a home broadband connection without timing out. No additional image editing software is needed, no Adobe subscription, and no Photoshop license, which makes the workflow accessible to occasional sellers who do not need a professional image editing toolchain.
Get better results with these expert suggestions:
Use Microsoft Edge because it is already installed
Microsoft Edge is pre-installed on every Windows 10 and Windows 11 computer, so it is available without any additional setup step. Open Edge from the taskbar, navigate to fixtools.io, and drag your PNG from File Explorer directly onto the converter window. No Chrome installation is needed for FixTools to work properly. Edge uses the same Chromium rendering engine as Chrome and has identical support for the Canvas API features used in browser-based image conversion, so the experience is functionally interchangeable between the two browsers.
Drag from File Explorer into the browser
On Windows you can drag a PNG file directly from File Explorer onto the FixTools browser tab without first opening a file picker dialog. If you tile File Explorer and your browser side by side using Windows key plus left arrow and Windows key plus right arrow, you can drag files between them without ever clicking an upload button. This is the fastest workflow for converting individual files, and it scales well to batches because you can select multiple PNGs in File Explorer with Ctrl-click and drag the whole selection at once.
Paint is fine for one-off conversions with no size requirements
If you just need a PNG converted to JPG and do not care about the exact file size or precise quality setting, Paint is fast enough for a single one-off file. Open Paint, press Ctrl+O to open the PNG, then Ctrl+Shift+S to save as, and choose JPEG from the format dropdown. The whole process takes about 15 seconds for one file. Use FixTools when you need quality control, batch conversion, file size feedback before download, or any output predictability that Paint does not offer through its fixed internal quality.
Check Ask where to save in Edge downloads
By default, Edge saves downloads to C:\Users\YourName\Downloads without prompting for a location. If you want converted JPGs to go to a specific folder such as a project directory or a synced OneDrive folder, go to Edge Settings then Downloads and enable Ask me what to do with each download. This lets you choose the save location for each converted file, which is useful when you are organising output into project-specific folders rather than dumping everything into a single Downloads pile that grows unwieldy over time.
