Why convert JPEG to PNG?
JPEG compression is lossy — each time a JPEG is saved, quality degrades slightly. Converting to PNG preserves the current state of your image in a lossless format, preventing further quality loss. PNG also supports transparency, making it ideal for logos, graphics, and images that need to be overlaid on different backgrounds.
- Lossless Quality: PNG preserves every pixel exactly as decoded from the JPEG.
- Editing Friendly: PNG is the preferred format for image editing workflows to avoid re-compression artifacts.
- Universal Compatibility: PNG is supported by every major operating system, browser, and design tool.
How to convert JPEG to PNG
- Select or drop JPEG/JPG files onto the workspace above.
- Since PNG is a lossless format, quality settings are automatically optimized.
- Press "Convert All" to decode and re-encode locally using Web Workers.
- Download the resulting PNG files individually or as a single ZIP archive.
Frequently Asked Questions
Will the file size increase?
Yes. JPEG uses lossy compression that creates smaller files. PNG uses lossless compression, so the resulting file will typically be 3-5x larger. This is expected and reflects the higher quality retention.
Can I recover quality lost by JPEG compression?
No. Converting to PNG preserves the current state of the image but cannot restore quality already lost during JPEG encoding. The conversion prevents further quality degradation from future saves.
Are my images uploaded to a server?
No. Vintix processes all conversions locally inside your browser using Web Workers and WebAssembly. Your files never leave your device.
