JPG to PNG Converter

About This Tool

The JPG to PNG Converter converts JPEG images to the PNG (Portable Network Graphics) format entirely in your browser using the Canvas API. PNG is a lossless format — it stores every pixel exactly, making it ideal for images that need to be edited further, screenshots, logos, and graphics with flat colors or transparency.

Note that converting from JPG to PNG does not recover any quality lost during the original JPG compression — the existing artifacts are preserved in lossless form. The PNG file will typically be larger than the JPG because it stores uncompressed pixel data.

How to Use

1. Drop a JPG or JPEG image onto the upload area or click to browse.
2. The tool automatically converts the image to PNG.
3. Review the dimension and file size information.
4. Click Download PNG to save the result.

Use Cases

Graphic designers convert JPG photos to PNG before opening them in editing software that works better with lossless formats. Developers need PNG for web graphics that require a transparent background (which can be added after conversion). Content creators convert JPG screenshots to PNG to avoid re-compression artifacts when uploading to platforms that re-compress images.

FAQ

• Will the PNG be higher quality than the JPG? — No. Converting JPG to PNG does not improve quality. Existing JPG compression artifacts are preserved in the PNG. The PNG will simply not add any new compression artifacts on future saves.
• Why is the PNG larger than the JPG? — PNG is lossless and stores full pixel data, so PNG files are generally larger than equivalent JPG files.
• Does this tool support transparency? — The conversion preserves any existing transparency in the source image. JPG has no alpha channel, so JPG sources will not have transparency in the output PNG.
