PNG to JPG Converter

PNG to JPG Converter is a free online tool that converts PNG image files to JPEG format. Upload your PNG file and download a JPG version instantly — all in your browser, with no server upload and no sign-up required. Adjust the JPEG quality level to control the balance between file size reduction and visual quality.

PNG (Portable Network Graphics) and JPEG are the two most widely used image formats on the web, and they are optimised for different types of content. PNG uses lossless compression — no image data is ever discarded, so the image decodes back to exactly the original pixels. PNG also supports transparency (alpha channel), making it the standard for logos, icons, and graphics that need to sit on different coloured backgrounds. JPEG uses lossy compression — it discards fine image details that human vision is least sensitive to, achieving much smaller file sizes at the cost of some quality loss.

The primary reason to convert PNG to JPEG is file size. A PNG photograph can easily be 3–5 times larger than the equivalent JPEG at good visual quality. For web images that do not require transparency — product photos, blog post images, background banners, and lifestyle photography — JPEG is almost always the better choice. A 2MB PNG photograph can become a 300–500KB JPEG at 80% quality with barely perceptible visual difference at typical screen sizes. Smaller images mean faster page loads, lower server bandwidth costs, and better Google Core Web Vitals scores.

One critical consideration when converting PNG to JPEG is transparency. JPEG does not support an alpha channel. If your PNG has transparent areas — a logo on a transparent background, a UI element with soft edges, or any graphic with see-through regions — those areas will be filled with a solid colour when converted to JPEG. Our tool uses white as the default background fill, which works for most logos and icons intended for use on white pages. A background colour picker lets you choose a different fill colour if needed.

There are situations where you should keep the PNG format rather than converting. Any image requiring transparency must stay PNG (or become WebP, which supports transparency). Images with text, sharp lines, and flat colours compress better and look sharper as PNG — JPEG's lossy compression creates visible blockiness (compression artefacts) around high-contrast edges. Screenshots of text-heavy interfaces almost always look better as PNG than as JPEG, often with smaller file sizes too.

Web developers convert PNG screenshots and design exports to JPEG to reduce page weight for images that don't require transparency. E-commerce platforms commonly require product images in JPEG format for upload. Social media platforms apply their own JPEG compression to uploaded images — starting with a well-compressed JPEG rather than a large PNG gives you more control over the final appearance after the platform re-compresses it. Photographers converting RAW exports to PNG for archival purposes often convert to JPEG for sharing and web delivery.

PNG to JPG Converter uses the HTML5 Canvas API. The uploaded PNG is drawn onto a canvas element; transparent pixels are filled with the chosen background colour. The canvas is then exported using the browser's JPEG encoder at your chosen quality level. The resulting JPEG is offered for immediate download. No data is sent to any server — the entire conversion runs in your browser.
