Convert PNG to JPG with a quality slider (10–100) and custom background color for transparency replacement. Shows before/after file size comparison. Batch convert up to 10 PNGs. Perfect for reducing file size for photos.
Upload up to 10 PNG images. Transparent areas in PNGs are filled with the background color you choose (default white) since JPG does not support transparency.
Use the quality slider (10–100) to control the JPG compression. Quality 85 is recommended for photos — good quality with significant size reduction. Set the background color to fill any transparent areas in your PNG.
Each file shows original PNG size vs output JPG size and percentage savings. Download individually or get all files as a ZIP.
PNG is lossless — it perfectly represents the original pixels. JPG is lossy — it discards some image data to achieve smaller file sizes. Converting PNG to JPG at quality 85–90 is nearly imperceptible for photographs. For graphics with sharp edges, solid colours, or text, JPG compression introduces visible artefacts. Use WebP instead for a better balance of quality and compression.
JPG does not support transparency. Any transparent pixels in your PNG are filled with a solid background colour before conversion. This tool lets you choose the background colour (default white). For images with transparency that need to stay transparent, use PNG to WebP or PNG to AVIF instead — both support transparency with better compression than PNG.
Convert to JPG when: the image is a photograph or complex real-world scene (JPG excels here), file size is more important than perfect quality, the image has no transparency, and you are targeting environments with limited WebP/AVIF support. Keep as PNG when: the image is a logo, icon, screenshot, or graphic with solid colours and sharp edges, or when transparency must be preserved.
Typical size reductions: photographs at quality 85 → 70–85% smaller than PNG. Illustrations and graphics at quality 85 → 30–60% smaller. The reduction depends heavily on image content. Photos compress very efficiently with JPG due to natural colour gradients. Graphics with large areas of solid colour compress better as PNG than JPG.
Quality 100: almost lossless, very large file — use only for print or archival. Quality 90: excellent quality, noticeably smaller than PNG — good for high-quality web images. Quality 85: recommended default — excellent for photographs with minimal artefacts. Quality 75: good for thumbnails and preview images. Quality 60: small files, visible artefacts on close inspection — acceptable for low-priority images. Below 60: significant quality loss, avoid for important images.
Yes — this tool processes up to 10 files at once. All files are converted with the same quality setting and background colour. Each file is downloaded separately with the same filename but .jpg extension. For bulk conversions of hundreds of files, command-line tools like ImageMagick (mogrify -format jpg -quality 85 *.png) are more efficient.
