What does this tool do?
This free JPG-to-PNG converter turns JPG images into lossless PNG files instantly in your browser. PNG preserves every pixel with zero further quality loss, making it ideal when a form or app strictly requires .png, or before repeated editing that would degrade a JPG.
How does the jpg to png converter work?
The JPG is decoded to raw pixels on a Canvas and re-encoded with PNG's lossless DEFLATE compression. Note this preserves current quality — it cannot restore detail the original JPG compression already discarded — but guarantees no additional loss ever.
Frequently Asked Questions
Does converting JPG to PNG improve image quality?
No — quality lost to JPG compression is gone permanently; conversion just stops any further loss. The PNG will look pixel-identical to the source JPG while being 2–5× larger. Convert when you need the format, not to "upgrade" quality.
When should I actually use PNG over JPG?
Use PNG for graphics with sharp edges (logos, screenshots with text, diagrams), anything needing transparency, and master copies you'll edit repeatedly. Use JPG (or WebP) for photographs where its perceptual compression is far more efficient.
Is the JPG to PNG converter really free?
Yes — 100% free with no hidden charges, trial limits, or premium tiers for core features. No account or email needed. The site is supported by non-intrusive display ads, which keeps every tool free for everyone.
Are my files private when using the JPG to PNG converter?
Completely. The JPG to PNG converter processes everything locally in your browser — your files are never uploaded to any server. When you close the tab, everything is gone. This makes it safe for confidential documents, client work, and personal photos.
Does the JPG to PNG converter work on mobile phones?
Yes. It's built mobile-first and works on any modern phone browser — iPhone (Safari) and Android (Chrome) included. You can pick files straight from your camera roll and download results directly to your device.
Do I need to install any software to use the JPG to PNG converter?
No. The JPG to PNG converter runs entirely in your web browser — no downloads, extensions, or signup. Open the page, use the tool, download your result. It works on Windows, macOS, Linux, ChromeOS, iOS, and Android.
