How to Convert JPG to PNG in 3 Steps
1. Select or drag and drop up to 10 JPG or JPEG files directly into the converter area.
2. Set optional maximum width or maximum height parameters if you want to scale down your images during processing.
3. Wait a moment for your browser to generate the new files, then download your PNGs individually or grab everything at once in a ZIP archive.
Instant In-Browser Conversion with Total Privacy
Traditional converters send your personal photographs, receipts, or confidential documents across the internet to a third-party server. FileFlip handles the entire conversion locally inside your browser using the HTML5 canvas engine. Your images are never uploaded, stored, or reviewed by anyone.
Because zero bytes leave your device, conversions complete virtually instantly without network upload delays. Furthermore, the tool caches directly to your device: once loaded, you can disconnect your Wi-Fi or turn on airplane mode and convert files entirely offline.
Understanding JPG vs. PNG
JPG relies on lossy compression, discarding fine detail and subtle color gradients to keep file sizes compact. Every time a JPG is modified and re-saved, it suffers generational loss, accumulating fuzzy compression artifacts around sharp lines.
PNG is a lossless format. While converting a JPG to PNG cannot restore detail already lost to JPEG compression, PNG prevents any further degradation. It preserves exact pixel data, making it ideal for images that require ongoing edits, sharp typography, or future transparency adjustments. Because PNG does not discard data, the resulting file is frequently larger than the original JPG.
When You Should Switch from JPG to PNG
Preparing assets for graphic design: If you plan to import a photo into editing software to add text, vectors, or masks, converting to PNG ensures successive saves will not introduce blocky artifacts.
Prepping for background removal: JPG files do not support alpha transparency. Switching to PNG provides the necessary canvas container before you mask out an object or isolate a product shot.
Preserving screenshots and logos: When photos contain crisp interface elements or high-contrast graphics, keeping them in PNG preserves line clarity across web and digital presentations.
