Large PNG files slow down websites and eat storage. Every time you upload a PNG to a server-based converter, you hand over your images to a third party. ConvertFile converts PNG to JPG directly in your browser. Your files stay on your device, and the result downloads in under 2 seconds.

PNG files store every pixel without compression, which produces large files. A 1920x1080 screenshot saved as PNG can be 2-5MB. The same image as a JPG at 90% quality is typically 200-500KB, a 50-80% reduction.
JPG is the better choice for photographs, social media uploads, email attachments, and any image where file size matters more than pixel-perfect accuracy. If your image has no transparency and no sharp text overlays, JPG will give you a smaller file with no visible quality loss.

PNG (Portable Network Graphics) is a lossless image format created in 1996 as a patent-free alternative to GIF. It supports full-color images with an alpha channel for transparency. PNG files preserve every pixel exactly, which makes them ideal for screenshots, logos, UI elements, and graphics with sharp text. The trade-off is file size: PNG images are typically 3-5x larger than equivalent JPG files for photographic content.
JPG (JPEG) is the most widely used image format on the web. It uses lossy compression to produce small files, discarding visual information that the human eye is unlikely to notice. At 85-90% quality, most people cannot tell the difference between a JPG and the original. JPG does not support transparency, and re-saving a JPG repeatedly causes gradual quality loss, a process called generation loss.
ConvertFile uses the HTML5 Canvas API to convert images directly in your browser. Your PNG files are never uploaded to a server. The conversion runs on your device's hardware, which is why it finishes in under 2 seconds. Once you close the tab, the converted files are gone from memory.
JPG uses lossy compression, so there is some quality reduction. At 90% quality, the difference is not visible to the human eye. Below 70%, you may start to see compression artifacts around sharp edges and text.
JPG files are 50-80% smaller than PNG for photographic images. This makes them better for websites, email attachments, and social media. If your image has no transparency, JPG is almost always the right choice for sharing.
No. The conversion happens entirely in your browser using the Canvas API. Your files never leave your device. You can verify this by disconnecting from the internet and running the conversion.
JPG does not support transparency. Transparent areas in your PNG will be replaced with a white background. If you need to keep transparency, convert to WebP instead.
Files up to 10MB are supported. Since processing runs locally in your browser, conversion speed depends on your device. Most files finish in under 2 seconds.
For photographs, 85-90% gives the best balance between file size and visual quality. For images with text or sharp edges, use 92-95% to reduce artifacts. Going above 95% gives diminishing returns on quality with much larger files.
Yes. You can add up to 2 files per batch. Each file converts independently, and you can download them all when finished.
No. The output JPG has the exact same width and height as the input PNG. Only the file format and compression method change.
