Why Convert JPG to PNG?

JPG images use "lossy" compression, which means some visual data is discarded to create smaller file sizes. While this is great for sharing photos, it creates blurry artifacts around text and sharp edges.

By converting your images to **PNG**, you stop the cycle of quality loss. This is essential for:

  • Logos and icons that require sharp edges
  • Screenshots and diagrams with readable text
  • Archiving original work for future editing
  • Preparing images for background removal

Frequently Asked Questions

Q: Is the JPG to PNG converter free?

A: Yes. Plainscan provides professional JPG to PNG conversion for free. Simply log in to access our secure cloud processing and batch conversion features.

Q: Does converting JPG to PNG improve quality?

A: It won't restore data lost during the original JPG save, but it prevents any further quality degradation, ensuring your image remains perfect for all future edits.

Frequently Asked Questions

What is the difference between JPG and PNG?

JPG is best for high-resolution photography and uses lossy compression to keep file sizes small. PNG is a lossless format that supports transparency and is better for graphics, logos, and images containing text.

Why convert JPG to PNG?

You should convert to PNG when you need to preserve pixel-perfect quality or add transparency. JPGs often suffer from artifacts around sharp edges and text, which PNG avoids entirely.

Is the JPG to PNG converter free?

Yes. Plainscan offers a professional-grade free tier for image conversion. Simply log in to your secure account to access our high-speed UK-based server facility.

Can I make a JPG transparent by converting it to PNG?

Conversion alone won't make a background transparent. However, once converted to PNG, you can use our "Remove Background" tool to create a clean alpha channel for your asset.

Is it safe to upload my photos to Plainscan?

Yes. We use enterprise-grade SSL for all transfers. Your images are processed on secure UK servers and are automatically and permanently deleted within 24 hours of your session.

How many JPGs can I convert at once?

Our tool supports robust batch processing. You can upload multiple files simultaneously and our servers will process them efficiently for instant high-quality PNG output.

Does converting JPG to PNG increase file size?

Yes, typically. Since PNG is a lossless format, it stores more data than a compressed JPG. This increase is normal for maintaining higher visual fidelity and edge sharpness.

Is PNG better for web SEO than JPG?

PNG is better for "on-page" SEO involving infographics and graphics with text. However, for large photos, we recommend converting to WebP to improve page load speeds and Core Web Vitals.

Which PNG format do you support (PNG-8 or PNG-24)?

Our converter defaults to high-fidelity PNG-24, ensuring full support for over 16 million colors and a complete 8-bit alpha channel for smooth transparency transitions.

Why is a login required for conversion?

Security is our priority. Requiring a login ensures that your proprietary image assets are processed in a private, encrypted environment accessible only to you.
