Convert JPG to PNG
Free, private, and instant — your files never leave your device.
JPEG uses lossy compression that permanently discards some image detail to achieve smaller files — a trade-off invisible in many photos, but visible as artifacts around sharp edges and text. PNG stores every pixel exactly using lossless compression, making it the better choice for screenshots, logos, and any workflow that involves further editing. Converting JPG to PNG stops additional quality loss from accumulating when you re-save the file. The output will be significantly larger than the original JPEG — that is expected, because PNG stores far more data per pixel.
JPEG
Joint Photographic Experts Group
- Lossy compression
- No transparency
- Best for: photographs, social media images, email attachments
PNG
Portable Network Graphics
- Lossless compression
- Supports transparency
- Best for: screenshots, logos, graphics with transparency, diagrams
How to Use
- 1
Drop your JPG file — the output format is already set to PNG.
- 2
No quality slider appears: PNG is always lossless, so there is nothing to configure.
- 3
Click "Convert to PNG" — conversion runs in your browser.
- 4
Download the PNG. Expect the file to be considerably larger than the original JPEG.
Frequently Asked Questions
Will converting JPG to PNG restore the original quality?
No. The detail discarded by JPEG compression is permanent and cannot be recovered. Converting to PNG preserves the image exactly as it currently is, without any further quality loss — but it cannot reconstruct what the JPEG algorithm removed when the file was first saved.
Why is the PNG file much larger than the JPG?
PNG stores every pixel losslessly, which requires significantly more data for photographic images. JPEG achieves its small size by discarding fine detail your eye barely notices. When you convert back to PNG, all that detail is stored again — but with the JPEG artifacts now locked in.
When should I convert JPG to PNG?
Three common reasons: (1) you plan to edit the image repeatedly and want to avoid JPEG artifacts accumulating with each re-save, (2) you need to overlay the image on a non-white background and want to add transparency in an editor, or (3) a tool or platform only accepts PNG.
Can I add a transparent background to the JPG during conversion?
Not with this converter — it changes the format without altering the image content. To remove a background or add transparency, open the PNG in an image editor such as Photoshop, GIMP, or Canva after converting.
