How to convert JPG to PNG (3 steps)

- Click Convert to PNG. The tool re-encodes your image using lossless PNG compression, preserving every pixel exactly.
- Download your PNG. The output has a .png extension. Download individually or all as a ZIP. Use in design software, upload portals requiring PNG, or overlay on any background with transparency intact.
JPG vs PNG — which format is right for you?
| Feature | JPG | PNG |
|---|---|---|
| Compression | Lossy | Lossless |
| Transparency | Not supported | Fully supported (alpha channel) |
| File size | Smaller (lossy) | Larger (lossless) |
| Best for | Photographs, realistic images | Logos, graphics, screenshots, text |
| Quality loss per save | Yes — re-encoding degrades quality | No — lossless re-saves |
When to use PNG instead of JPG
- Logos and brand assets — PNG preserves sharp edges and supports transparency, so logos work on any background colour.
- Screenshots and diagrams — PNG keeps text crisp where JPG introduces blurring artefacts around letters.
- Images with flat colours — PNG compresses solid-colour areas more efficiently than JPG.
- Source files for editing — saving intermediate editing steps as PNG avoids accumulating JPG compression degradation.
- Portals requiring PNG format — some government and academic portals specify PNG only for uploaded documents.
FAQ
Why convert JPG to PNG?
PNG is lossless and supports transparent backgrounds. Use PNG when you need to overlay an image on any background colour, use it in design software without quality loss, or preserve crisp edges on logos and text.
Does converting JPG to PNG improve quality?
No — JPG artefacts already present in the source image remain in the PNG. The benefit is that no further quality is lost during PNG encoding. Converting freezes current quality rather than restoring it.
Will the PNG be larger than the original JPG?
Usually yes. PNG is lossless and stores more data. A 200 KB JPG photo might become 600 KB to 1 MB as PNG. For file-size efficiency on photos, keep JPG or use WebP instead.
Does PNG support transparent backgrounds?
Yes — PNG fully supports alpha channel transparency including semi-transparent pixels. JPG does not support transparency at all. For logos or cutouts needing a transparent background, PNG is the correct format.
Can I batch convert multiple JPGs to PNG?
Yes — drop multiple JPG files at once. Each converts separately and you can download them individually or all together as a ZIP file using the "Download all as ZIP" button. Conversion runs entirely in your browser.
