What happens to transparent areas in my PNG when converting to JPG?

JPG does not support transparency, so any transparent or semi-transparent pixels in your PNG will be replaced with a solid background color — white by default. If your PNG has a colored or gradient background behind transparent areas, you should set the fill color in the converter to match your intended background before converting. Failing to do this results in white halos around subjects that were originally on a transparent layer.

Is my image uploaded to a server during conversion?

No. This PNG to JPG converter runs entirely in your browser using JavaScript and WebAssembly. Your image file is read locally by the browser, processed in memory, and the result is made available for download — no data is sent to any external server at any point. This means your personal, medical, legal, or proprietary images remain completely private.

How much smaller will my JPG file be compared to the original PNG?

For photographic images, JPG at quality 85 is typically 60–80% smaller than an equivalent PNG. For example, a 3 MB PNG photograph might compress to 400–600 KB as a JPG. Graphics with large flat-color areas — like screenshots or illustrations — may see less dramatic size reductions because PNG's lossless compression already handles those areas efficiently.

Can I convert multiple PNG files to JPG at once?

For single-file conversion, use this tool directly. If you need to convert multiple PNG files to JPG simultaneously, use our Batch Image Processor tool, which lets you upload dozens of images and apply the same conversion settings to all of them in a single job. The batch tool outputs all converted files in a convenient ZIP archive.

What is PNG to JPG Converter?

The PNG to JPG converter transforms lossless PNG images into compressed JPG files entirely in your browser, making it ideal for reducing file size for photos and web assets. During the PNG to JPG conversion, any transparent areas are filled with a white background since JPG does not support transparency. This tool is the fastest way to shrink image files when transparency is not needed and smaller file sizes are the priority.

Why use PNG to JPG Converter?

JPG's lossy compression algorithm is specifically designed for photographic images, producing files 60–80% smaller than their PNG equivalents with minimal perceptible quality loss at quality settings of 80 or higher. Converting in the browser means your images never leave your device, eliminating privacy concerns associated with server-side converters. Secondary benefits include faster page load times, reduced storage costs, and broad compatibility across every operating system, email client, and image viewer.

How it works

E-commerce stores frequently convert product photos from PNG to JPG to reduce page weight and improve Core Web Vitals scores without sacrificing visual quality. Photographers sharing galleries online use PNG to JPG conversion to make high-resolution shots practical for email attachments and social media uploads. Web developers converting design exports or screenshots to JPG get dramatically smaller assets that accelerate site performance.

Pro Tip

Use a quality setting between 80 and 90 for the best balance of file size and visual fidelity — going below 75 introduces visible compression artifacts on edges and gradients. If your PNG contains a non-white background color behind transparency, set the background fill color before converting to avoid unexpected white halos.

Frequently Asked Questions

Yes, JPG uses lossy compression, which means some image data is permanently discarded during encoding. The amount of quality loss depends on the quality setting you choose — at 85–90, the difference is virtually imperceptible on photographic images, while settings below 70 will produce noticeable blurring and color banding. For graphics with sharp edges, text, or solid colors, quality loss is more visible at lower settings than it is for natural photos.
