Frequently Asked Questions

Common questions about JPG to PNG and client-side processing.

Does converting JPG to PNG improve image quality?

Converting JPG to PNG wraps the image data in a lossless format to prevent any further compression degradation during subsequent edits or saves. However, existing JPEG compression artifacts from the original file cannot be removed.

Why is the resulting PNG file size larger than the original JPG?

JPG uses lossy compression with aggressive quantization, while PNG uses lossless deflate compression. A larger file size is normal and expected when saving photographic pixels into PNG.

Can I convert multiple JPG images at once?

Yes. You can select multiple JPG or JPEG files simultaneously. FILEMORPH processes them locally in batch mode.

Are my photos uploaded to any server?

No. The conversion runs entirely within your browser using client-side Canvas APIs. Your photos never leave your device.
