It is part of ToolsMonk's image tools collection, so you can finish the job without downloading software, creating an account, or jumping between multiple websites.
This tool is especially useful for workflows such as converting large png screenshots and exports into far smaller jpgs for email and web, turning transparent png logos into jpgs with a chosen background colour for documents and slides, and reducing the weight of photo-style pngs that don't need transparency. Because it runs directly in your browser, you can use it on desktop, tablet, or mobile while keeping the process fast and easy for one-off tasks as well as repeat work.
PNG to JPG is also a strong fit for people searching for png to jpg, png to jpeg, and convert png, because it combines a simple interface with instant results and privacy-friendly processing.

PNG to JPG is a powerful free online tool available on ToolsMonk that helps you convert png to jpg with adjustable quality and custom background color for transparency. Whether you're a professional, student, or casual user, our png to jpg provides instant, accurate results right in your browser without requiring any software installation or account creation.
As part of our Image Tools collection, this tool is designed with simplicity and power in mind. All processing happens client-side, ensuring your data remains completely private and secure. The tool works seamlessly across all modern browsers on desktop, tablet, and mobile devices.
PNG to JPG converts lossless PNG images into the compact, universally supported JPG format. PNG is excellent for transparency and sharp graphics but produces large files for photographic content; JPG trades a little quality for a much smaller file, which is ideal when you don't need transparency.
The key thing to get right is transparency. Because JPG can't store transparent pixels, they have to be filled with a solid colour — and if a tool defaults that to black, transparent logos look wrong. This converter gives you a background-colour picker so you decide exactly what shows behind the image, with white as the usual safe choice.
A quality slider and live before/after preview let you tune the JPG compression and see the file-size saving in real time, while the original dimensions stay untouched. Everything runs in your browser via the Canvas API, so your images are processed privately on your device with no uploads.
If your goal is the smallest possible web image while keeping transparency, consider Convert to WebP instead; if you need different dimensions, pair this with Resize Image. All three are free, watermark-free, and have no usage limits.
Always set the background colour before converting a transparent PNG — white suits documents, but match your slide or page colour for a seamless look
Keep PNG (don't convert) for logos, icons, and screenshots with sharp text, where PNG stays crisper and may even be smaller
If you need a small file AND transparency, convert to WebP instead of JPG using the Convert to WebP tool
