Convert PNG to JPG Online — Reduce File Size Instantly
PNG files are lossless and often huge — a simple screenshot can be 2-5MB, and a high-resolution photo saved as PNG can exceed 20MB. Converting PNG to JPG can reduce file size by 70-90% while keeping visual quality virtually identical. This is especially useful when you need to meet email attachment limits, upload images to forms with size restrictions, or optimize website load times. Our free converter runs entirely in your browser with no file uploads, and automatically strips metadata for privacy.
Why Convert PNG to JPEG?
PNG is great for graphics with sharp edges, text, and transparency — but it's overkill for photos, screenshots you want to share, and web images where file size matters. A 4MB PNG screenshot becomes a 200KB JPEG with no visible quality loss. This matters for email attachments (most email services limit attachments to 25MB), website performance (faster loading), and storage space. If your image doesn't need transparency, JPG is almost always the better choice for sharing and web use. Consider that a website loading ten PNG product images at 3MB each forces visitors to download 30MB of images alone — the same images as JPEG would total just 3-5MB, loading six times faster. For photographers and content creators, PNG is sometimes used as an editing format to avoid generation loss from repeated JPEG saves. Once your editing is finished, converting the final version to JPEG for delivery is standard practice. The quality difference at 90%+ is invisible even on high-resolution Retina displays. One important caveat: if your PNG has transparency (like a logo with a transparent background), that transparency will be lost during conversion to JPEG. Transparent areas become white. If you need both small file size and transparency, convert to WebP instead.
How It Works
Drop your PNG file onto the page (or click to browse). The browser's Canvas API decodes the PNG pixels, then re-encodes them as JPEG at your chosen quality level. This entire process happens in your browser's memory — your image never touches any server. The quality slider lets you control the tradeoff — 90%+ is visually lossless for photos, 70-80% is great for web use with noticeably smaller files, and 50-60% gives maximum compression for thumbnails and preview images. For screenshots with text, staying above 85% ensures text remains crisp and readable. All EXIF metadata is stripped automatically during the conversion. This includes GPS coordinates, camera information, timestamps, and software details. The result is a clean JPEG file that's safe to share publicly without leaking personal information.
All Supported Formats
While this page is optimized for PNG to JPEG conversion, our universal image converter supports all major formats: JPEG, PNG, WebP, HEIC, AVIF, JPEG XL, TIFF, SVG, BMP, and GIF. All conversions run 100% in your browser with automatic metadata stripping.
Frequently Asked Questions
How much smaller will my JPG be compared to PNG?
Typically 70-90% smaller. A 3MB PNG screenshot usually becomes 200-400KB as a JPEG at 90% quality. Photos see even bigger reductions because photographic content compresses very efficiently with JPEG. The exact ratio depends on image content — photos compress better than text-heavy screenshots.
Does converting PNG to JPG lose quality?
JPEG is a lossy format, so there is some quality reduction. However, at 85-95% quality settings, the difference is invisible to the human eye for photos and most screenshots. Only images with very fine text, thin lines, or sharp edges may show visible compression artifacts at lower quality settings.
Will I lose transparency when converting PNG to JPG?
Yes. JPEG does not support transparency. Transparent areas in your PNG will be converted to white (or the canvas background color). If you need to preserve transparency, convert to WebP instead, which supports both transparency and smaller file sizes than PNG.
What quality setting should I use?
For photos and general use: 85-92%. For web images where size matters: 70-80%. For archival quality: 95-100%. Below 60% you'll start seeing visible JPEG artifacts (blocky edges, color banding). For screenshots with text, stay above 85% to keep text readable.
Is this PNG to JPG converter safe to use?
Yes. Your images are processed entirely in your browser using the Canvas API. No files are uploaded to any server, no data is transmitted, and we have no access to your images. The conversion also strips all metadata, making the output files safer to share online.
Can I convert multiple PNG files at once?
Yes. Our batch mode lets free users convert up to 5 PNG files at once and Pro users up to 10. All files are processed locally and can be downloaded individually or together as a ZIP archive. This is ideal for converting an entire folder of screenshots.
How does PNG compare to JPG for website images?
For website performance, JPEG is almost always better for photos and complex images. A typical web page with JPEG images loads 3-5x faster than the same page with PNG images. Google PageSpeed Insights will flag large PNG files as an optimization opportunity. The exception is images that require transparency or pixel-perfect rendering, like logos and icons.
