Frequently Asked Questions
JPG files are much smaller than PNG for photos, making them better for web use, email attachments, and storage.

No. All conversion happens in your browser. Your files never leave your device.
JPG uses lossy compression, so there will be a small quality reduction. We use 92% quality by default, which is visually indistinguishable for most images.
What is PNG to JPG?
PNG to JPG conversion is the standard approach when you need to dramatically reduce image file size for web publishing, social media uploads, or email attachments. PNG files, especially screenshots and graphics, are often 3–10× larger than their JPG equivalents because PNG uses lossless compression. Converting to JPG applies smart lossy compression that removes imperceptible visual data while keeping the image looking great at 80%+ quality settings. This is a fundamental workflow for bloggers, marketers, and web developers who need to keep page load times fast. One important note: transparent areas in your PNG will be filled with a white background in the JPG output, since the JPEG format does not support alpha channel transparency. Our converter processes everything using the Canvas API in your browser — no images are transmitted to any server.

Frequently Asked Questions
How much smaller will the JPG be compared to the original PNG?
For photographic content, JPG at 80% quality is typically 3–7× smaller than PNG. For screenshots and graphics with flat colors, the reduction may be less dramatic.
What happens to transparent parts of my PNG?
Transparent areas are filled with a solid white background in the JPG output. If you need to preserve transparency, keep the file as PNG or convert to WebP instead.
Will the JPG look noticeably worse?
At 80%+ quality settings, the difference is imperceptible to most viewers for photographic content. Lower settings may introduce visible compression artifacts around high-contrast edges.
Can I control the compression level?
Yes. Use the quality slider to choose between smaller file size (lower quality) and better visual fidelity (higher quality).
Is my PNG image sent to a server for conversion?
No. The conversion runs entirely in your browser using the HTML5 Canvas API. Your image is processed in browser memory on your device and downloaded directly — no server is involved.
