Online PNG to JPG Converter with Quality Control and Batch Processing
Converting PNG images to JPG is one of the most common image tasks on the web. PNG files preserve every pixel with lossless compression, which makes them excellent for screenshots, logos, and graphics with transparency. However, that lossless quality comes with larger file sizes. JPG uses lossy compression that discards visual information the human eye barely notices, resulting in dramatically smaller files. Take full control with a quality slider ranging from 10% to 100%, allowing you to strike the perfect balance between file size and visual clarity for every image.
How to Convert Your PNG Files
Getting started takes seconds. Click the Upload PNG button or drag your files directly onto the workspace. Your images are processed locally through the HTML5 Canvas API, which draws each PNG onto a custom background and exports it at your preferred quality level. Results show up instantly in the sidebar with a clear file size comparison, while the interactive preview panel lets you inspect the final output with full zoom control.
Adjust Quality to Match Your Needs
Starting at a default of 92%, the quality slider provides a professional balance of visual fidelity and meaningful storage savings for most photos. For web thumbnails and social media images, dropping to 80% or lower can cut file sizes by 60-80% with barely noticeable quality loss. For print-quality images or detailed artwork, push the slider to 95-100% to keep as much detail as possible.
Handle Transparency, Compare Results, and Process Batches
One of the trickiest parts of converting PNG to JPG is handling transparency. Since JPG has no alpha channel, transparent pixels need a solid color behind them. While the output defaults to a white background, you can easily select any custom color through the settings panel to replace transparent areas. Logos and icons with transparent backgrounds look clean against your chosen color, and you can preview the result before downloading.
Side-by-Side Visual Comparison
Use Compare mode to view the original and converted images simultaneously, then drag the slider to spot quality differences in real time. Accurate file sizes are displayed on both sides so you can immediately see the storage savings. This visual verification ensures your settings are perfect before you commit to a download.
Batch Processing for Multiple Files
Select multiple PNG files from the file picker or drag a group of images onto the workspace. Each file appears in the sidebar with a thumbnail, file name, dimensions, and size comparison. Click any file to preview it in the main panel, or use Download All to save every converted image at once. Changing the quality slider and clicking Re-convert applies your new settings to all files in the batch.
Your Images Stay Private in Your Browser
Every conversion runs locally using JavaScript and the HTML5 Canvas API. No images are uploaded, no data is sent to any server, and no account or registration is needed. The browser draws your file, replaces transparency with your chosen background, and exports a JPG blob that remains securely in your local memory until you decide to save it or close the tab. Use this tool confidently with sensitive photos, proprietary graphics, or client work.
