PNG to JPG converter
PNG excels at graphics with transparency, but photographic PNGs are often huge. Converting to JPEG dramatically shrinks file size by using lossy compression — transparency is flattened against a background color. All processing stays in your browser.
How to convert PNG to JPG
1. Upload your PNG file.
2. Pick a background color if the image has transparency.
3. Set JPEG quality (80% is a sensible default).
4. Download the JPG result.
Conversion examples
Screenshot for documentation
A full-screen PNG screenshot may be several megabytes. JPG at 85% is usually fine for wiki pages and support tickets.
Photo exported as PNG by mistake
Camera apps sometimes save PNG. Convert to JPG for sharing in messaging apps with size caps.
Email newsletter image
Marketing teams often require JPG under 200 KB — convert and compress after checking text legibility.
When to convert PNG to JPG
• When file size matters and you do not need transparency.
• When uploading to platforms that prefer or require JPEG.
• When sharing photos quickly without cloud storage.
When to keep PNG
• When you need an alpha channel (logos on varied backgrounds).
• When the image has sharp text or UI elements that JPEG may blur.
• When lossless archival is required.
Transparency and backgrounds
Before converting logos with partial transparency, pick a background that matches where the JPG will appear. White is standard; dark sites may need #1a1a1a or similar to avoid light fringes.
Artifacts on flat colors
JPEG assumes photographic content. Solid red UI buttons may show speckles at low quality. PNG or WebP lossless modes suit flat design assets better.
Size vs quality trade-off
Measure the result: if JPG at 75% looks identical to 90% on your target display, use the smaller file. Side-by-side zoom on critical areas before publishing.
Frequently asked questions
What happens to transparency?
Transparent pixels are composited onto the background color you choose — usually white.
What quality should I pick?
80–85% works for most photos. Raise to 90% if you see banding in gradients.
Will text stay sharp?
JPEG can halo around high-contrast edges. For text-heavy screenshots, keep PNG or try higher quality.
Can I convert back without loss?
No — JPG compression is lossy. Keep the original PNG if you might need it.
Is data sent to a server?
No — conversion uses local canvas encoding.
Is WebP a better choice?
Often yes for the web — try PNG to WebP if browsers you target support it.
