What Does the PNG to JPG Converter Do?
The PNG to JPG Converter converts PNG image files to JPEG format entirely in your browser. Upload up to 20 PNG files at once, choose your JPEG quality level, set a background color to replace transparent areas, and download the converted images — all without sending your files to any server.
PNG and JPG serve different purposes. PNG supports lossless compression and transparency, making it ideal for logos, illustrations, and screenshots. JPEG uses lossy compression tuned for photographic images, producing much smaller file sizes at comparable visual quality. Converting PNG to JPG is standard practice when sharing photos online, uploading to platforms that prefer JPEG, or reducing file sizes for web performance.
Because PNG supports transparency and JPEG does not, this tool lets you choose a background color (white by default) to fill transparent areas before conversion. The result is a clean, flat JPEG without unexpected black or checkerboard backgrounds.
Everything runs locally using the browser's HTML5 Canvas API. Your photos, screenshots, and design assets never leave your device.
How It Works
- 1 Upload PNG Files: Drag and drop up to 20 PNG images into the upload zone, or click to select from your device. A file queue appears showing each file name and size.
- 2 Set Quality & Background: Adjust the JPEG quality slider (80% default is recommended for web use). Choose a background color to replace transparent PNG areas — white is standard for document use.
- 3 Click Convert: The tool processes each PNG through the HTML5 Canvas, fills transparent areas with the chosen background, and encodes the result as JPEG at your quality level.
- 4 Download Output: Single file downloads directly. Multiple files download as a ZIP archive — ready to extract and use.

Common Use Cases
Web Performance
Convert large PNG screenshots and illustrations to JPEG to reduce file sizes by 60–80%, improving page load times.
Email Attachments
Reduce photo attachment sizes before emailing — keeping below attachment limits without compromising visual quality.
Platform Upload Compatibility
Many platforms prefer JPEG for photos. Convert PNGs to JPG to ensure compatibility with social platforms, CMS systems, and email tools.
Best Practices for PNG to JPG Conversion
- Use 80% Quality for Web: At 80% JPEG quality, most photographic images reduce by 40–70% with barely visible quality loss — ideal for web publishing.
- Choose the Right Background Color: White (#FFFFFF) is standard for documents and presentations. Use a custom color if the image will appear on a colored background.
- Don't Convert Logos to JPEG: If your PNG has sharp edges, text, or transparency you need to preserve, keep it as PNG. JPEG compression introduces artifacts in high-contrast areas.
- Keep Original PNGs: Always retain your original PNG files. JPEG conversion is lossy — you cannot perfectly reconstruct the original from the JPG.
- Batch Convert for Efficiency: Use the batch upload feature (up to 20 files) to convert entire sets of screenshots or image exports in one session.
- Never Upload Private Images Online: This tool processes everything locally — your files stay on your device with zero cloud storage risk.
Frequently Asked Questions
Yes. All conversion runs using the HTML5 Canvas API in your browser. Your files never leave your device — no uploads, no cloud processing.
JPEG does not support transparency. This tool fills transparent areas with the background color you choose (white by default) before encoding as JPEG.
Up to 20 PNG files per session. When converting multiple files, the output is packaged as a ZIP archive for easy download.
Yes, significantly. PNG files of photographic images can be 3–5× smaller when converted to JPEG at 80% quality, with minimal perceptible quality loss.
Yes. Once the page is loaded, you can disconnect from the internet and continue converting images. All processing runs in your browser.
No server-side limit. Processing is constrained by your browser's available memory. Most devices handle images up to 20–50MB comfortably.
Yes. Use the JPG to PNG converter tool for that direction. Note that converting back from JPEG to PNG doesn't restore lost quality — always keep original PNGs if quality matters.
