PNG to JPG

PNG and JPG are the two most common image formats on the web, but they serve very different purposes. PNG is lossless and supports transparency, which is great for logos, icons, and screenshots. JPG is lossy and compresses photos far better than PNG, which is why it dominates camera files, social media uploads, and email attachments. If you have a folder of PNG files that are too big to share, converting them to JPG is the fastest way to shrink them, often by 70 to 90 percent.

Our PNG to JPG converter runs entirely inside your browser. Your original images are never uploaded to a server, never logged, and never seen by anyone but you. The conversion uses the native HTML5 Canvas API, which is the same engine browsers use to render every image you see online, so the results are reliable and fast.

1. 1

   Open the converter

   Click anywhere on the upload box above, or drag PNG files directly from your file explorer. You can drop one image or fifty, the converter handles batch jobs without any extra setup.
2. 2

   Pick a quality level

   Use the quality slider that appears once a file is loaded. A value between 80 and 92 percent works well for most photos and screenshots. Lower values create smaller files but may introduce visible artifacts in areas with smooth gradients or text.
3. 3

   Convert

   Click the convert button. Each image is processed locally in a few milliseconds. A summary panel shows the original size, the new size, and how much space you saved.
4. 4

   Download

   Download files individually with the icon next to each result, or grab them all with the download all button. Files are saved with the same base name as the original but with a .jpg extension.

PNG was designed in the 1990s as a free, lossless replacement for the GIF format. JPG (also written JPEG) was designed in the 1980s specifically to compress photographs. They each have strengths the other lacks.

Convert when you want smaller files

The number one reason to convert PNG to JPG is file size. A 4 megapixel screenshot saved as PNG can easily exceed 5 MB. The same image as JPG at 90 percent quality is often under 500 KB and looks identical to the eye. If you are emailing photos, posting on a forum that has upload limits, or building a website that needs to load fast, JPG is almost always the right choice for photographic content.

Will my image lose transparency?

Yes. JPG does not support transparency. Any transparent pixels in your PNG are filled with white in the JPG output. If transparency matters, keep the file as PNG, or use WebP which supports both lossy compression and transparency.

Why is my JPG slightly blurry compared to the PNG?

JPG compression works by averaging similar colors in 8x8 pixel blocks. On screenshots and graphics with sharp edges or text, this can produce visible halos or smearing. If text legibility is important, use a higher quality setting (95 or 100 percent), or keep the file as PNG.

Is there a maximum file size?

There is no hard limit set by the converter, but very large images (over 50 MB or 100 megapixels) may slow down older devices because the entire conversion runs in your browser using your device CPU and RAM. On modern laptops and phones, even 4K and 8K photos convert in well under a second.

This matters when you are converting sensitive material like passport scans, medical reports, ID cards, or confidential business documents. Most online converters upload your file to their servers, run the conversion there, and then send the result back. Even if they delete the file afterward, you have no way to verify that. With ToolHub, the file is never uploaded in the first place.
