How to Compress PNG Images on Windows 10 and 11 (5 Easy Methods)
By admin · Jun 18, 2026
Whether you're a Windows 10 or Windows 11 user, there are multiple ways to compress PNG images and reduce their file sizes. Some methods use built-in Windows tools, while others use free online tools or third-party software. In this guide, we'll cover 5 practical methods.
Method 1: Use compresspngfile.com (Easiest — Recommended)
The fastest and most effective method — no software installation needed.
- Open your web browser (Chrome, Edge, or Firefox)
- Go to compresspngfile.com
- Drag and drop your PNG file onto the upload area
- Wait 2–3 seconds for compression
- Click Download to save your compressed PNG
Result: Up to 80% file size reduction with full transparency preserved. Works on Windows 10 and Windows 11 without installing anything.
Method 2: Use Microsoft Paint (Built-in, Basic)
Windows Paint can reduce PNG file size by resizing the image dimensions. Note: Paint does not compress the image data itself — it only helps if your image is larger than needed.
- Right-click your PNG file > Open with > Paint
- Click the Resize button in the toolbar
- Check "Maintain aspect ratio" and reduce the percentage (e.g., to 50%)
- Click OK and then File > Save As > PNG
Limitation: Paint cannot perform actual PNG data compression — only dimension reduction.
Method 3: Use the Windows Photos App
- Open your PNG in the Photos app (double-click the file)
- Click the three-dot menu (…) in the top right
- Select "Resize" from the menu
- Choose a smaller size or enter custom dimensions
- Click "Save resized copy"
Like Paint, this method reduces dimensions but does not perform true PNG compression.
Method 4: Compress via File Explorer (ZIP method)
- Right-click your PNG file in File Explorer
- Select "Send to" > "Compressed (zipped) folder"
- Windows creates a .zip file containing your PNG
Note: The PNG file inside the ZIP is unchanged. This method is best for email transfers, not for web optimization.
Method 5: Use PowerShell with pngquant (Advanced)
For developers or power users, pngquant is a command-line tool that delivers excellent PNG compression on Windows.
- Download pngquant.exe from pngquant.org
- Place pngquant.exe in the same folder as your PNG files
- Open PowerShell and navigate to that folder
- Run:
.\pngquant.exe --quality=65-80 yourfile.png - A new file named yourfile-fs8.png will be created
