Convert JPG to PNG
Convert JPG and JPEG images to PNG locally in your browser. Create PNG files for compatibility while keeping dimensions and visual orientation unchanged.
What this JPG to PNG converter does
NexKit JPG to PNG converts JPG and JPEG images into PNG files directly in your browser. It is a focused format-pair page, so the input is restricted to JPEG and the output is fixed to PNG.
This route is for compatibility with PNG-only forms, editors, and workflows. It changes the file container and encoding, but it does not restore image details already lost through JPEG compression.
How to convert JPG to PNG
Upload one or more JPG or JPEG files, then run conversion. Successful PNG files can be downloaded individually or together as a ZIP.
If a selected file is not a real JPEG, the page rejects it instead of trusting the filename extension. PNG, WebP, GIF, SVG, HEIC, AVIF, and renamed files are not accepted here.
PNG output and image quality
PNG output is useful for compatibility, but it can be much larger than the original JPG. Converting to PNG does not remove JPEG compression artifacts or recover lost detail.
JPG images do not contain an alpha channel, so PNG output remains visually opaque. This converter does not create a transparent background.
Privacy and local processing
JPG files are decoded and converted locally in your browser. NexKit does not upload selected images to a server or send file contents to a cloud image service.
Canvas re-encoding usually does not preserve original EXIF, GPS, ICC, or other metadata. EXIF orientation is handled through the browser decode path used by the image tooling.
Frequently Asked Questions
Are my JPG files uploaded?
No. JPG to PNG conversion runs locally in your browser. The selected JPG files are not uploaded to NexKit servers by this tool.
Does converting JPG to PNG improve image quality?
No. JPG to PNG changes the output format for compatibility, but it does not restore lost detail or remove compression artifacts from the original JPEG.
Why is the PNG file larger than the JPG?
PNG uses a different encoding approach and can be much larger than JPEG, especially for photos. This route is for PNG compatibility rather than compression.
Will the PNG have a transparent background?
No. JPG images do not include transparency, so this converter keeps the visual image opaque unless the original browser-decoded source already has alpha.
