Typically 50-80% smaller than the original PNG. Photos see the biggest reductions. At 80% quality, most images look identical to the original while being significantly smaller.
JPG does not support transparency. Any transparent areas in your PNG are filled with a white background during conversion. If you need to keep transparency, stay with PNG or use WebP.
80% is an excellent default for most images. At this setting, the quality difference is imperceptible to the human eye. Use 60-70% for web thumbnails where file size matters most, or 90-95% when you need near-perfect quality.
PNG uses lossless compression — perfect quality but larger files, supports transparency. JPG uses lossy compression — smaller files but some detail is discarded, no transparency. Use PNG for graphics and logos, JPG for photographs.
Need to reduce the size of a PNG image? Our free online converter transforms any PNG file into a compact JPG with adjustable quality. No software to install, no accounts to create, no files uploaded to remote servers. Just a fast, private conversion right in your browser.
PNG files use lossless compression, which preserves every pixel perfectly but produces large file sizes. For photographs and images where pixel-perfect quality is not critical, JPG is the better choice. JPG's lossy compression produces files that are typically 50-80% smaller while maintaining visual quality that is indistinguishable from the original at reasonable quality settings.
Upload your PNG file, adjust the quality slider to your preference, and click convert. The Canvas API renders your image onto a white background (since JPG does not support transparency) and encodes it as a JPEG at your chosen quality level. You get an instant preview so you can verify the result before downloading.
Quality is a trade-off between file size and visual fidelity. At 80%, most images look identical to the original while being significantly smaller. For web thumbnails and social media, 60-70% delivers excellent results with maximum file savings. For print or archival purposes, 90-95% preserves nearly all detail. The preview lets you compare before committing.
Personal photos, confidential screenshots, proprietary designs — whatever your image contains, it stays on your device. Unlike online converters that upload your files to remote servers, BrowserCrunch processes everything locally in your browser. Your images are never stored, transmitted, or seen by anyone.
No file size limits. No daily conversion caps. No watermarks. No sign-up required. Convert as many PNG images to JPG as you need, whenever you need to. Adjustable quality, instant preview, and completely private.
