How to Convert JPG to PNG Online Free
Converting JPG to PNG is one of the most common image format changes, especially when you need transparency support or lossless quality. JPG files use lossy compression that discards some image data to reduce file size, while PNG preserves every pixel perfectly. Whether you need a transparent background for a logo, crisp text rendering for a screenshot, or simply want to stop further quality degradation from repeated edits, converting to PNG is the right move.

Understanding the fundamental differences between JPG and PNG helps you decide when conversion makes sense.
| Feature | JPG | PNG |
|---|---|---|
| Compression | Lossy - discards data to shrink size | Lossless - preserves all pixel data |
| Transparency | Not supported | Full alpha channel support |
| File Size | Smaller for photographs | Larger, especially for complex photos |
| Best For | Photos, gradients, large images | Logos, text, screenshots, graphics |
| Color Depth | 24-bit (16.7 million colors) | Up to 48-bit with alpha channel |
| Editing | Quality degrades with each save | No quality loss on repeated saves |
How to Convert JPG to PNG Online
- 1
Upload your JPG file
Drag and drop your JPG or JPEG file into the converter. You can also click the upload area to browse your files. Multiple files can be uploaded at once for batch conversion.
- 2
Verify the output format
Make sure PNG is selected as the target format. The converter will automatically detect your input file as JPG.
- 3
Start the conversion
Click the Convert button. The conversion happens entirely in your browser, so your files are never uploaded to any server. This process typically takes just a few seconds.
- 4
Download your PNG file
Once conversion is complete, click Download to save your new PNG file. The original JPG file remains unchanged on your device.
Recommended Conversion Settings
While JPG to PNG conversion is straightforward, these settings help you get the best results.
Use RGBA if you plan to add transparency later. RGB is sufficient if you just want lossless quality without transparency needs.
24-bit preserves the original JPG color range. 32-bit adds an alpha channel for transparency, increasing file size slightly.
PNG compression is always lossless, so maximum compression reduces file size without any quality penalty. It just takes slightly longer to process.
Common Issues When Converting JPG to PNG
Converted PNG file is much larger than the original JPG
This is expected behavior. PNG uses lossless compression, which produces larger files than JPG lossy compression, especially for photographs. Consider whether you truly need PNG, or if the JPG quality is acceptable for your use case.
Image looks identical after conversion
The visual appearance should be identical since PNG preserves all pixel data from the JPG. The benefit is that further edits and saves will not degrade quality. Note that converting to PNG cannot recover quality already lost during JPG compression.
Background is white instead of transparent
Converting JPG to PNG does not automatically make backgrounds transparent. JPG files have no transparency data. After conversion, you need to use an image editor to remove the background and create transparency.
File is too large for my website
Use PNG compression optimization tools to reduce file size without quality loss. Alternatively, consider WebP format which offers both lossless quality and smaller file sizes than PNG.
When You Should Convert JPG to PNG
Not every JPG file needs to be converted to PNG. Here are the scenarios where conversion provides real benefits.
- You need to add a transparent background to the image for use in designs or presentations
- The image contains text, line art, or sharp edges that benefit from lossless compression
- You plan to make multiple rounds of edits and want to avoid cumulative quality loss
- You are creating screenshots or UI mockups where pixel-perfect accuracy matters
- The image will be used as a logo or icon overlay on different backgrounds
- You need to preserve fine details in technical diagrams or charts
Frequently Asked Questions
Does converting JPG to PNG improve image quality?
No. Converting JPG to PNG preserves the current quality but cannot recover data lost during the original JPG compression. The benefit is that future edits and saves will not cause additional quality degradation.
Why is my PNG file so much bigger than the JPG?
PNG uses lossless compression, which keeps every single pixel intact. JPG achieves smaller sizes by discarding visual data. A typical photograph can be 3-5 times larger as PNG compared to a quality-80 JPG.
Can I make the background transparent after converting to PNG?
Yes, but the conversion itself does not create transparency. After converting to PNG, use an image editing tool or background remover to make specific areas transparent. The PNG format supports full alpha transparency.
Is JPG or PNG better for social media?
Most social media platforms accept both formats but will re-compress your image regardless. For photographs, JPG is typically fine. For images with text overlays, logos, or graphics, PNG preserves sharper edges before the platform recompresses.
Will converting JPG to PNG remove compression artifacts?
No. Compression artifacts like banding, mosquito noise, and blockiness are baked into the pixel data. Converting to PNG preserves these artifacts perfectly rather than making them worse, but it cannot remove them.
Can I convert JPG to PNG on my phone?
Yes. Our online converter works in any modern mobile browser. Simply open the converter page, upload your JPG file from your photo library, and download the converted PNG file directly to your device.
How long does JPG to PNG conversion take?
The conversion typically takes 1-3 seconds for standard-size images. Since the conversion runs entirely in your browser, speed depends on your device rather than internet connection. Very large images may take up to 10 seconds.
Converting JPG to PNG is essential when you need transparency support, lossless editing, or pixel-perfect image preservation. While PNG files are larger than their JPG counterparts, the tradeoff is worthwhile for logos, graphics, screenshots, and any image requiring repeated edits. Use our free online converter to switch formats instantly without losing any quality from your original file.
