How to Use
Drag and drop your PNG file into the upload zone, click to browse, or paste directly from clipboard with Ctrl+V. Files up to 20 MB are supported.
Set the JPG quality (1–100%). Higher quality means larger file size. 85% is the sweet spot — visually lossless with 70–90% size reduction. Use the Quality vs Size chart to find your ideal setting.
If your PNG has transparent areas, choose a background color. JPG doesn't support transparency, so transparent pixels will be filled with white by default (or your chosen color).
Click "Convert Now" to instantly convert your image in the browser. Use the before/after slider to compare quality, then download your JPG or copy it directly to clipboard.
What Is PNG to JPG Conversion?
PNG (Portable Network Graphics) and JPG (Joint Photographic Experts Group) are two of the most widely used image formats. PNG uses lossless compression, preserving every pixel perfectly — but this makes files significantly larger. JPG uses lossy compression, which discards some visual data to achieve much smaller file sizes while keeping images that look nearly identical to the human eye.
Converting PNG to JPG is one of the most common image optimization tasks. A PNG screenshot that is 2.4 MB can often become a JPG at just 300–400 KB with no visible quality difference, making it perfect for websites, email attachments, social media uploads, and anywhere that load speed matters.
When Should You Convert PNG to JPG?
- Reducing file size for web — JPG images load faster, improving page speed and SEO. Google PageSpeed Insights often flags large PNG photos as an optimization opportunity.
- Sharing photos — JPG is the universal standard for photographs. WhatsApp, email attachments, and most social platforms handle JPG best.
- Reducing storage — If you have many PNG screenshots or exports, converting them to JPG can reduce storage consumption by 70–90%.
- Compatibility — Some older software and platforms have limited PNG support. JPG is universally supported everywhere.
The Transparency Trade-Off
The most important difference between PNG and JPG is transparency. PNG supports a full alpha channel, meaning pixels can be partially or fully transparent. JPG has no transparency support whatsoever. When converting a PNG with transparency to JPG, transparent pixels must be replaced with a solid color. Our tool defaults to white (the most common choice), but you can pick black or any custom color in the Advanced Options.
If your PNG has a transparent background and you need to preserve that transparency, consider converting to WebP instead, which supports both transparency and much better compression than PNG.
Privacy and Security
All conversion happens entirely inside your browser using the Canvas API. Your images are never uploaded to any server. There is no backend, no cloud processing, and no data retention. You can safely convert images containing personal information, confidential content, or sensitive data.
Frequently Asked Questions
JPG uses lossy compression, so there is technically some quality loss during conversion. However, at quality settings of 80–90%, the difference is invisible to the human eye for photographic images. The before/after comparison slider on this tool lets you see the difference at the pixel level before downloading. For graphics with sharp edges, text, or flat colors, some visible artifacts may appear at lower quality settings — use higher quality (90+) for those.
JPG does not support transparency. Transparent pixels in your PNG will be filled with a solid background color. By default this is white. You can change it to black or a custom color using the Advanced Options section. If you need to preserve transparency, convert to WebP instead — it supports transparency with better compression than PNG.
It depends heavily on the image content. Photographs typically see 70–90% file size reduction (a 3 MB PNG photo becoming 300–500 KB JPG). Screenshots and graphics with solid colors, text, and sharp edges compress less aggressively — expect 40–70% reduction. The Quality vs File Size chart on this page shows you exactly how different quality settings affect the output size for your specific image.
The default of 85% is the industry-standard sweet spot for most use cases — virtually no visible quality loss with excellent compression. Use 90–95% for high-quality prints or professional photography. Use 70–80% for web images where fast loading is the priority. Anything below 70% may show visible compression artifacts, especially on images with text or sharp edges. Use the interactive slider to preview the result before downloading.
Yes. Switch to the "Batch Mode" tab and drop up to 20 PNG files at once. The tool converts them sequentially (to avoid memory issues on mobile devices) and shows individual progress for each file. When all conversions are done, you can download a single ZIP file containing all converted JPGs, or download them individually.
No. This tool is 100% client-side. Your image is read from your device using the FileReader API and converted entirely within your browser using the HTML5 Canvas API. The image data never leaves your device, is never sent to any server, and is never stored anywhere. It is completely private and secure.
By default, EXIF data (camera make and model, GPS location, date taken, etc.) is stripped during conversion. This is actually a privacy benefit — sharing images without GPS data prevents others from knowing where a photo was taken. Canvas-based conversion naturally discards EXIF. If you need to preserve EXIF, you would need a server-side tool that supports metadata transfer.
Yes. Open the Advanced Options section and enable "Resize". Set your desired maximum width and/or height in pixels. The tool maintains your image's aspect ratio by default (so a 3840×2160 image resized to max width 1920 will become 1920×1080). This is useful when you want to reduce both file size and dimensions simultaneously.
