What is JPG to PNG Conversion?
When you convert JPG to PNG, you transform a lossy-compressed image into a lossless format. JPG (JPEG) uses DCT-based compression that discards some image data to achieve smaller file sizes. PNG, on the other hand, uses DEFLATE compression that preserves every single pixel exactly as it is.
This means that a JPG to PNG converter gives you an image file that will never lose additional quality when saved again. While the original quality lost during JPG compression cannot be recovered, converting to PNG ensures no further degradation occurs during future edits or saves.
Our free JPG to PNG tool processes everything directly in your browser using the Canvas API, so your images are never uploaded to any server. This makes it the most private and fastest way to convert JPG to PNG online.
How to Convert JPG to PNG Online
Upload Your JPG
Drag and drop your JPG or JPEG files, or click to browse. You can upload up to 20 files at once.
Auto-Convert
Your images are automatically converted to PNG format. No quality settings needed — PNG is always lossless.
Download PNG Files
Download individual files or all converted images as a ZIP archive.
When You Need JPG to PNG Conversion
Logo & Branding
Logos need transparent backgrounds. Convert to PNG to place your logo on any background color or image without white boxes.
Image Editing Workflows
If you plan to edit an image multiple times, work in PNG to avoid compounding JPG compression artifacts with each save.
Web Graphics & Screenshots
PNG excels at sharp edges, text, and flat colors. Screenshots, UI mockups, and infographics look crisper in PNG format.
Print Design
For print materials requiring maximum fidelity, PNG preserves every detail. Use PNG for source files before final output.
JPG vs PNG: Technical Comparison
| Feature | JPG (JPEG) | PNG |
|---|---|---|
| Compression | Lossy (DCT-based) | Lossless (DEFLATE) |
| Transparency | Not supported | Full alpha channel |
| Color Depth | 24-bit (16.7M colors) | 24-bit or 32-bit (with alpha) |
| Best For | Photos, gradients | Graphics, logos, screenshots |
| File Size | Smaller | Larger (2-5x typically) |
| Repeated Editing | Quality degrades each save | Quality always preserved |
| Animation | Not supported | APNG (limited support) |
| Browser Support | Universal | Universal |
| Metadata | EXIF data (camera info) | Text chunks |
File Size: What to Expect After Conversion
Converting from JPG to PNG will almost always result in a larger file. This is the trade-off for lossless quality. Here is a typical comparison for a 1920×1080 photo:
- JPG at 80% quality: ~120 KB
- JPG at 100% quality: ~450 KB
- PNG (full color): ~850 KB
- PNG-8 (256 colors): ~180 KB
The size increase is worth it when you need lossless editing, transparency, or pixel-perfect reproduction. For web photos where file size matters most, consider keeping JPG format or using our JPEG compressor.
Tips for Best Results
- Use JPG to PNG for graphics, logos, and screenshots — not large photos
- If you need transparency later, convert to PNG now to preserve your options
- For web photos where loading speed matters, consider keeping the JPG format
- Use batch conversion to process multiple files efficiently
- The original JPG quality is preserved — but quality already lost in JPG encoding cannot be recovered
- After converting, you can use our PNG compressor to optimize the file size
