Convert JPG to PNGNo software required · Works in any browser
Lossless Output
PNG uses lossless compression. Once converted, your image won't degrade no matter how many times it's saved.
Web-Ready Format
PNG is supported everywhere — browsers, design tools, CMS platforms, and social media. Universal compatibility.
Instant Processing
Conversion takes milliseconds per image. No server queues, no waiting. Process hundreds of files in seconds.
Fully Private
Images are converted locally using your browser's canvas API. No files leave your device at any point.
How It Works
Add JPG Images
Drag and drop your JPG or JPEG files. Add as many images as you need — there's no file limit.
Convert to PNG
Each image is decoded and re-encoded as PNG in your browser. The process preserves every pixel of detail.
Download PNG Files
Save images individually or download all converted files together as a ZIP archive.
Common Use Cases
Preventing Further Quality Loss
Every time a JPG is re-saved, it loses quality. Converting to PNG freezes the current quality level — future edits and saves won't degrade it further.
Design & Editing Workflows
Design tools like Figma, Canva, and Photoshop work better with PNG for layer composition. Convert source images to PNG before importing into design projects.
Screenshots & Technical Images
PNG is the standard for screenshots, UI mockups, and diagrams because it preserves sharp edges and text without JPG's compression artifacts.
Print-Ready Files
Some print services prefer PNG over JPG for its lossless quality. Convert photos to PNG when preparing files for high-quality prints or merchandise.

Frequently Asked Questions
Why convert JPG to PNG?
JPG is lossy — every save degrades quality. Converting to PNG stops this degradation. PNG also supports transparency, has no compression artifacts, and preserves sharp edges in text and graphics. It's the better format for editing, design work, and archiving.
Will converting JPG to PNG improve image quality?
No. Converting to PNG preserves the current quality but can't recover detail already lost to JPG compression. What it does is prevent any further quality loss in future edits and saves. Think of it as locking in what you have.
Will the PNG file be larger than the original JPG?
Usually yes. PNG's lossless compression produces larger files than JPG's lossy compression, typically 3-5x larger for photos. This is the trade-off for perfect quality. If file size matters more, stick with JPG.
Can I add transparency to my converted PNG?
The conversion itself doesn't add transparency — your JPG pixels are preserved as-is with a solid background. To add transparency, you'd need to use an image editor or our Remove Background AI tool after converting to PNG.
Is batch conversion supported?
Yes. Add as many JPG files as you want and they'll all be converted to PNG simultaneously. Download them individually or as a single ZIP file. There's no file count limit.
