How to Convert PNG to JPG
Vizua is a free PNG to JPG converter that runs entirely in your browser. Drop your PNG image, set the JPEG quality level, and download a smaller, universally compatible JPG file. No upload, no account, no watermarks.
PNG files are excellent for graphics and screenshots, but they can be 5-10x larger than JPEG for photographic content. Converting to JPG dramatically reduces file size, making your images easier to share, email, and upload to platforms with size restrictions.
PNG vs JPG — Which Format to Use
- Use PNG for logos, icons, text-heavy screenshots, diagrams, and anything requiring transparency
- Use JPG for photographs, social media images, email attachments, and web content where file size matters
- Key difference — PNG is lossless (perfect quality, larger files); JPG is lossy (slight quality trade-off, much smaller files)
What Happens to Transparent PNGs?
JPEG does not support transparency. When Vizua converts a transparent PNG to JPG, transparent areas are rendered as white. This is the standard behavior — if your image has critical transparency (like a logo on a transparent background), you may want to keep it as PNG or convert to WebP, which supports both transparency and efficient compression.
Choosing the Right Quality
The quality slider controls JPEG compression. At 90-95%, the output is nearly indistinguishable from the original PNG but still significantly smaller. At 75-85%, you get the best balance of size and quality for most uses. Below 70%, compression artifacts become noticeable, especially on images with sharp text or fine details.
Batch Conversion
Need to convert multiple PNG files to JPG? Drop them all at once — Vizua processes each file with the same quality setting, shows individual results with before/after sizes, and offers both individual downloads and a bulk ZIP option. Perfect for converting screenshot libraries or design exports.
100% Private — No Upload
Your images stay on your device throughout the entire process. Vizua converts PNG to JPEG entirely within your browser — no pixel data is ever sent to any server. This makes it safe for confidential documents, personal photos, and proprietary design files. The tool continues working offline after the page loads.
Frequently Asked Questions
How do I convert PNG to JPG?
Drop your PNG file into Vizua, adjust the quality slider (80-90% recommended), and click Download. The conversion happens instantly in your browser — no files are uploaded to any server. You can convert multiple PNGs at once.
What is the difference between PNG and JPG?
PNG uses lossless compression (no quality loss) and supports transparency, making it ideal for logos, icons, and graphics. JPG uses lossy compression, producing much smaller files for photographs but without transparency support. Converting PNG to JPG is useful when you need smaller files and don't need transparency.
What happens to transparency when converting PNG to JPG?
JPEG does not support transparency. When you convert a transparent PNG to JPG, the transparent areas are filled with white. If your image has transparency that you need to preserve, consider converting to WebP instead — it supports both transparency and smaller file sizes.
Will converting PNG to JPG reduce quality?
Yes, slightly — JPEG is a lossy format, so some detail is lost during conversion. However, at 85-90% quality, the difference is virtually invisible to the human eye. The trade-off is a dramatically smaller file size, often 5-10x smaller than the original PNG for photographs.
When should I convert PNG to JPG?
Convert when you need smaller file sizes and don't need transparency — uploading photos to social media, sending images via email, optimizing website images, or meeting file size limits. Keep PNG format for logos, screenshots with text, diagrams, and any image requiring transparency.
