Why Convert JPG Images to PNG?

JPG images use lossy compression, which degrades quality every time an image is saved. PNG files use lossless compression, preserving exact colors and sharp details. Because PNG preserves uncompressed pixel detail, converted PNG file sizes are typically larger than compressed JPG originals.

Frequently Asked Questions

Everything you need to know about converting JPG to PNG locally.

How does browser-based JPG to PNG conversion work?

The converter uses your web browser built-in Canvas API to read your JPG image data and encode it as a high-quality PNG image. The entire process runs directly inside your device memory (RAM), requiring zero server interaction.

Are my uploaded images kept completely private?

Yes, 100%. Your files never leave your device and are never uploaded to any cloud server, database, or external service. Once you close or refresh the tab, your temporary image memory is completely cleared.

Can I convert multiple JPG photos at the same time?

Yes. You can select or drag multiple JPG and JPEG photos at once. Each file is converted in parallel, and you can download them individually or as a single combined ZIP archive.

Will converting JPG to PNG increase my file size?

Yes, this is normal. JPG uses lossy compression while PNG uses lossless compression to preserve full pixel quality. Because PNG preserves uncompressed detail, converted PNG files are typically larger than the original JPG.
