PNG to JPG
Convert PNG images to JPEG format.
Convert a PNG file to JPG for smaller file sizes and universal compatibility. PNG is great for screenshots and graphics with transparency, but JPG is usually the better choice for photos you plan to share or upload, since it produces much smaller files at a similar visual quality.

How to use PNG to JPG
Two steps, and nothing to install.
Drop your PNG file
Drop your PNG onto the tool, or click to browse and select it from your device. The image is read straight into the browser and never uploaded.
Download your JPG
The tool flattens any transparency, re-encodes the image as JPEG and hands you the file to download immediately.

How this works in your browser
The conversion happens on an HTML5 canvas in your browser. Your PNG is decoded and drawn onto a canvas, and because JPEG has no alpha channel, any transparent pixels are composited onto a solid white background at that point rather than being dropped. The canvas is then handed to the browser’s built-in JPEG encoder, which applies the lossy discrete-cosine-transform compression JPEG is built on. That single re-encode is where the size saving comes from and also why the step is one-way: the discarded detail is gone from the output, not recoverable by converting back.
PNG to JPG vs. upload-based online tools
| Feature | PNG to JPG (in-browser) | Upload-based online tools |
|---|---|---|
| File upload required | No - never leaves your device | Yes - file is sent to a server |
| Processing queue | None - starts instantly | Often, especially at peak times |
| Watermark on output | Never | Common on free plans |
| Usage limits | None - free, unlimited use | Often capped per day or file size |
| Works offline once loaded | Yes, for most tools | No - requires a live connection |
| Account required | No | Often, for anything beyond a trial |
Who uses PNG to JPG
Meeting upload size limits
Shrink an oversized PNG screenshot or export so it fits under the file size cap on a form, email attachment or marketplace listing.
Speeding up a web page
Photographic images served as PNG are often several times larger than they need to be. JPG cuts the weight without a visible difference at normal viewing size.
Sending photos that open anywhere
Hand someone a JPG when you want zero compatibility questions, since every device, email client and photo viewer reads it.
Frequently asked questions
What it can and cannot do, and what happens to your files.
What happens to transparent areas?
JPG has no transparency support, so transparent areas in your PNG are filled with white.
Why is the JPG file so much smaller?
JPG uses lossy compression tuned for photographic detail, while PNG is lossless, which is why PNG files are typically much larger for the same photo.
Can I control the JPG quality?
The tool uses a high-quality default setting that keeps files small without a visible quality loss for most images.
When should I not convert PNG to JPG?
Keep the PNG if the image has transparency you need, or if it is a logo, screenshot, diagram or anything with sharp text and flat colour. JPG compression blurs hard edges and adds faint halos around text, which is exactly where PNG performs better.
Can I convert the JPG back to PNG later?
You can change the container back, but not recover what was discarded. JPG compression permanently throws away detail, so converting back to PNG gives you a lossless copy of the already-compressed image, not the original.
Is my image uploaded anywhere?
No. The conversion runs entirely inside your browser tab, so the file never leaves your device.
