Convert PNG to JPG
Free, private, and instant — your files never leave your device.
PNG uses lossless compression that preserves every pixel — great for screenshots and graphics, but the files can be 5–10× larger than an equivalent JPEG for photographic content. JPEG applies lossy compression that discards imperceptible detail to achieve dramatically smaller file sizes. Converting PNG to JPG is the right move when you need to share a photo-heavy image and file size matters more than pixel-perfect fidelity. One caveat: JPEG does not support transparency, so any transparent areas in your PNG will become white.
PNG
Portable Network Graphics
- Lossless compression
- Supports transparency
- Best for: screenshots, logos, graphics with transparency, diagrams
JPEG
Joint Photographic Experts Group
- Lossy compression
- No transparency
- Best for: photographs, social media images, email attachments
How to Use
- 1
Drop your PNG file or click to browse — the output format is already set to JPEG.
- 2
Adjust the quality slider. 85–90% is typically indistinguishable from the original in most photos; lower values create smaller files but may introduce softness around edges.
- 3
Click "Convert to JPEG" — conversion runs entirely in your browser.
- 4
Download the JPG. Transparent areas in the original PNG will appear white in the output.
Frequently Asked Questions
Does converting PNG to JPG remove transparency?
Yes. JPEG does not support an alpha channel. Any transparent or semi-transparent pixels in the source PNG are composited onto white in the JPG output. If your image has a transparent background you want to preserve, use PNG-to-WebP instead.
Will converting PNG to JPG reduce image quality?
At quality settings of 85% or above, the difference is barely noticeable to the eye in photographs. Quality loss becomes more visible at low settings or in images with sharp edges, text, or flat-color areas — those compress poorly in JPEG.
Why is the JPG file so much smaller than the PNG?
JPEG uses a lossy DCT algorithm that discards fine spatial detail the eye barely perceives — detail that PNG stores without compromise. A PNG of a photograph stores every pixel losslessly, which is why PNG photos are far larger.
Can I convert back to PNG if I change my mind?
Yes — use the JPG-to-PNG converter. The PNG will be lossless going forward, but any quality lost during the PNG→JPG step is permanent. Converting back to PNG produces a larger file without recovering the discarded detail.
