PNG to JPG Converter
Convert PNG images to JPG in seconds. Upload a PNG, choose the output quality, and download a compressed JPG — usually a fraction of the original file size. Everything happens in your browser, so your image is never uploaded to a server.
How to Use
Click the upload area and select your PNG (or any image). Adjust the quality slider — 80–95% keeps the image looking sharp while cutting file size — then click Convert to JPG. You'll see the original and converted sizes plus how much you saved, and can download the JPG with one click.
Why This Tool Is Useful
PNG files are lossless and often very large, especially for photos. JPG uses lossy compression that shrinks photographic images dramatically with little visible difference — ideal for web pages, email attachments, and anywhere file size matters. Converting also strips the alpha channel, which is sometimes required by systems that don't accept transparency.
PNG vs JPG — What Changes
PNG is lossless and supports transparency, which makes it perfect for logos, screenshots, and graphics with flat colour — but file sizes balloon for photographs. JPG is lossy: it discards some detail to achieve much smaller files, and it has no transparency support.
Converting a photo from PNG to JPG typically cuts the file size by 60–90% with no visible loss at a sensible quality setting.
What Happens to Transparency
JPG has no alpha channel, so any transparent areas in your PNG have to become a solid colour. This converter fills transparency with white before encoding — the standard approach — so you won't get the black backgrounds some converters produce.
If you need to keep transparency, stay with PNG (or use WebP, which supports both compression and alpha).
Choosing the Right Quality
The quality slider controls the compression trade-off. Higher keeps more detail but produces a larger file. The table below is a good starting guide.
Why Convert in the Browser
Most online converters upload your image to their servers, which means your file — potentially a private screenshot or document — leaves your device. This tool uses the browser's Canvas API, so the conversion happens locally and nothing is transmitted, stored, or watermarked.
