JPG to PNG Converter - Free Online Tool
What is a JPG to PNG converter?
A JPG to PNG converter transforms JPEG images into PNG format. While JPG uses lossy compression that discards some image data, PNG is lossless and preserves every pixel exactly. This conversion is useful when you need to edit an image without further quality loss, add transparency, or work with formats that require PNG. The tool processes images entirely in your browser.
How to use the JPG to PNG converter
- Upload your JPG file: Drag and drop or click to select a JPEG image from your device. Files up to 10MB are supported.
- Preview the result: See your image displayed before downloading.
- Download your PNG: Click the download button to save the converted image instantly to your device.
Why use this JPG to PNG tool?
- Stop quality degradation: Once converted to PNG, further edits won't introduce additional compression artifacts.
- Add transparency later: PNG supports alpha channels, allowing you to add transparent backgrounds in image editors.
- Better for graphics: PNG handles sharp edges, text, and solid colors without the blurring that JPG introduces.
Use case 1: Prepare photos for heavy editing
Convert JPG photos to PNG before extensive editing in Photoshop or GIMP to prevent quality loss from repeated saves.
Use case 2: Create images with transparency
Start with a JPG photo, convert to PNG, then remove the background in an image editor to create a transparent cutout.
Use case 3: Screenshots and documentation
Convert JPG screenshots to PNG for documentation where crisp text and sharp edges matter.
JPG vs PNG comparison
- Compression: JPG uses lossy compression; PNG is lossless.
- File size: JPG files are smaller; PNG files are larger.
- Transparency: JPG doesn't support it; PNG does.
- Quality on re-save: JPG degrades each time; PNG stays unchanged.
- Best for: JPG excels at photos and web images; PNG is ideal for graphics, editing, and screenshots.
Common errors
Output file is much larger
PNG is lossless, so files are significantly larger than JPG—often 3–5x bigger. This is normal and expected.
Image still has artifacts
Converting JPG to PNG doesn't remove existing compression artifacts. The damage from JPG compression is permanent; PNG just prevents further degradation.
Can't add transparency directly
The converter outputs a PNG with a solid background. To add transparency, you'll need to use an image editor after conversion.
Tips and proven approaches
- Only convert to PNG if you need the lossless format; don't convert just to convert.
- For web use, PNG photos are inefficient. Consider keeping photos as JPG or converting to WebP.
- PNG excels for images with text, logos, screenshots, and graphics with sharp lines.
- If file size matters, use JPG to WebP for better compression.
