Free JPG to PNG Converter
Convert JPEG images to PNG format instantly — no upload, no account, no limits.
JPG to PNG conversion switches from lossy to lossless compression. PNG preserves every pixel exactly, making it ideal for graphics, logos, screenshots and images with text where compression artefacts would be visible. PNG also supports full transparency, which JPG does not. Conversion runs entirely in your browser using the Canvas API — your image never leaves your device.

When Should You Use PNG Instead of JPG?
PNG (Portable Network Graphics) is a lossless format, meaning no image quality is lost during compression. It supports transparency (alpha channel), making it ideal for logos, icons, screenshots and any image where sharp edges and text need to remain crisp. JPG (JPEG) is a lossy format optimized for photographs — it produces smaller file sizes but degrades quality slightly with each save.
Convert JPG to PNG when you need to preserve maximum quality, add transparency, or use the image in graphic design software. Note that PNG files are typically larger than JPG — if file size matters more than quality, consider keeping the JPG format.
