Why Convert JPEG to PNG?

JPEG is great for photos, but it has two significant limitations: no transparency support and lossy compression. Every time you edit and save a JPEG, you lose a bit more quality. PNG solves both problems.

Converting your JPEG files to PNG makes sense when you need transparent backgrounds, plan to edit the image multiple times, or have graphics with text and sharp edges. In our testing, images with logos, screenshots, or diagrams look noticeably cleaner as PNG files.

How to Convert JPEG to PNG

  1. Upload your JPEG file - Drag and drop or click to select your image
  2. Confirm PNG as output - PNG is selected as your target format
  3. Download your PNG - Your converted file is ready instantly

The entire process takes seconds. No software installation, no account creation, no watermarks.

JPEG vs PNG: Understanding the Difference

Both formats have their place, and knowing when to use each saves you time and produces better results.

JPEG Characteristics

  • Lossy compression - Smaller files, but quality degrades with each save
  • No transparency - Every pixel must have a color
  • Best for photographs - Complex color gradients compress well
  • Smaller file sizes - Typically 5-10x smaller than PNG

PNG Characteristics

  • Lossless compression - No quality loss, no matter how many times you save
  • Full transparency support - Alpha channel allows partial and full transparency
  • Best for graphics - Sharp edges, text, and solid colors stay crisp
  • Larger file sizes - The trade-off for lossless quality

In our testing, a typical 2MB JPEG becomes an 8-12MB PNG. That's normal and expected with lossless compression.

When to Convert JPEG to PNG

Adding Transparent Backgrounds

Planning to remove the background in Photoshop, GIMP, or Canva? Convert to PNG first. JPEG cannot store transparency data, so even after removing the background, you'd have to save as PNG anyway. Start with PNG and skip the extra step.

Multiple Editing Sessions

If you're going to edit an image multiple times over days or weeks, convert to PNG before you start. Each time you save a JPEG, compression artifacts accumulate. PNG preserves your work exactly as you left it. In our testing, images edited and saved 5+ times as JPEG showed visible degradation, while PNG remained identical to the original.

Screenshots and Interface Elements

Screenshots with text, buttons, and sharp UI elements look significantly better as PNG. JPEG compression creates fuzzy halos around text and hard edges. If you're documenting software or creating tutorials, PNG is the right choice.

Logos and Graphics

Converting logos from JPEG to PNG prevents the blurry artifacts around edges that JPEG creates. If someone gave you a logo as JPEG and you need it on different backgrounds, convert to PNG, then remove the background properly.

When NOT to Convert

Honest advice: sometimes staying with JPEG makes more sense.

  • Simple photo sharing - If you're just sending photos to friends or posting online, JPEG works fine
  • Storage concerns - PNG files are much larger; don't convert your entire photo library
  • Already compressed photos - Converting JPEG to PNG won't restore quality lost during initial JPEG compression
  • Web performance - JPEG loads faster on websites due to smaller file size

Converting JPEG to PNG preserves current quality going forward but cannot undo existing compression artifacts. Think of it as stopping further degradation, not reversing damage.

Technical Details

Our converter processes your JPEG and outputs a PNG-24 file with full color depth (16.7 million colors). The conversion preserves every pixel exactly as it appears in your JPEG source.

PNG uses DEFLATE compression, which is lossless. Your file will be larger, but mathematically identical in visual quality to the input. No color banding, no additional artifacts, no quality reduction.

For those working with transparency, note that converting alone doesn't make your image transparent. You get a PNG with the same solid background as your original JPEG. To add transparency, you'll need to remove the background in image editing software after conversion.

Batch Conversion

Need to convert multiple JPEG files at once? Upload your entire batch and convert them all to PNG simultaneously. In our testing, batch processing 50 images took under a minute. All processing happens in your browser, so your images never leave your device.

Related Conversions

Depending on your needs, other formats might work better:

  • JPEG to WebP - Modern format with good compression and transparency support, smaller than PNG
  • JPEG to GIF - Limited to 256 colors, but supports simple transparency and animation
  • PNG to JPG - Going the other direction when you need smaller file sizes

For most transparency and editing workflows, PNG remains the standard choice due to universal compatibility across all software.

Works on All Devices

Our JPEG to PNG converter runs entirely in your browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • iPhone, iPad, Android tablets and phones

No plugins, no downloads, no waiting for server processing. Your files convert locally for maximum speed and privacy.

Pro Tip

If you're preparing images for a design project with multiple editing rounds, convert all your JPEGs to PNG at the start. This prevents quality degradation throughout your workflow. When you're done editing, you can always export final versions as JPEG for smaller file sizes.

Common Mistake

Thinking that converting JPEG to PNG will restore lost quality or automatically add transparency. It won't do either. PNG simply prevents further degradation and enables transparency - you still need to actually remove backgrounds in editing software.

Best For

Images headed for editing workflows, graphics with text or logos, screenshots, or any image where you need to add transparent areas. Also ideal for archiving important images you may need to edit later.

Not Recommended

Don't batch-convert your entire photo library to PNG. You'll use 5-10x more storage with no practical benefit for photos you're just keeping. Only convert when you actually need PNG's specific features.

Frequently Asked Questions

No. Converting changes the format but keeps the same image content. Your PNG will have the same solid background as the original JPEG. To add transparency, you need to remove the background in image editing software like Photoshop or GIMP after converting.

Converting to PNG preserves current quality and prevents future degradation. However, it cannot restore quality already lost during JPEG compression. Any existing artifacts in your JPEG will remain in the PNG.

PNG uses lossless compression, which preserves every pixel exactly. JPEG uses lossy compression that discards data to achieve smaller sizes. A typical JPEG might be 5-10 times smaller than an equivalent PNG. The larger file size is the trade-off for lossless quality.

Yes, they are identical formats. The only difference is the file extension length (.jpeg vs .jpg). Both work exactly the same way and can be converted to PNG using this tool.

No. For regular photos you're just storing or sharing, JPEG is fine and saves significant storage space. Convert to PNG only when you need transparency, plan multiple editing sessions, or have images with text and sharp graphics.

Yes, you can always convert PNG to JPEG. However, that conversion will apply JPEG compression and reduce file size at the cost of some quality. The lossless quality you preserved in PNG would be lost when converting back.

Our converter outputs PNG-24 format with 24-bit color depth, supporting over 16 million colors. All colors from your original JPEG are preserved exactly without any color reduction or banding.

Your images are processed entirely in your browser. They never leave your device or get uploaded to any server. This makes conversion fast, private, and secure.

Yes. Upload multiple files and convert them all to PNG in one batch. Each file is processed individually and available for download as separate PNG files.

Since processing happens in your browser, there's no server-imposed limit. Your only constraint is your device's available memory. Most modern devices handle images up to 50MB without issues.

Both support transparency. PNG has universal compatibility across all software and browsers. WebP produces smaller files but isn't supported by all image editors. For web use, WebP is more efficient. For editing workflows, PNG is safer.

JPEG compression creates visible artifacts around sharp edges and text, which screenshots have plenty of. PNG preserves these hard edges perfectly. That's why screenshots should always be saved as PNG, not JPEG.
