What is JPG to PNG Converter?
A JPG to PNG converter changes the file format of an image from the lossy JPEG compression format to the lossless PNG format. While JPG is excellent for photographs where small compression artefacts are acceptable in exchange for smaller file sizes, PNG is preferred when you need pixel-perfect quality, transparent backgrounds, or images that will be edited and re-saved multiple times.
PNG uses lossless compression, which means every pixel in the output is identical to the input — there is no quality degradation during the conversion itself. This makes PNG the right choice for logos, screenshots, icons, illustrations, and any image that contains text or sharp edges where JPEG artefacts would be noticeable.
This tool performs the conversion entirely in your browser using the HTML5 Canvas API. No files are uploaded to a server, your images remain completely private, and there are no file size limits imposed by network transfer. Simply upload one or more JPG files, and download the converted PNGs ready to use.
How to Use JPG to PNG Converter
- Upload your JPG file
Click the upload area or drag and drop one or more JPG or JPEG images from your device.

Key Benefits
PNG compression is lossless, so the converted image retains every pixel of detail from the original.
Images are processed in your browser using Canvas API — no server upload, no data retention.
Convert multiple JPG files at once without waiting — all processing runs in parallel in the browser.
The PNG output supports an alpha channel, making it easy to add transparency in a subsequent editing step.
Frequently Asked Questions
Almost always yes. PNG uses lossless compression, so files are typically 2–5× larger than the equivalent JPG. This is the trade-off for having no quality loss.
No. Converting to PNG stops further quality loss but cannot recover detail that was discarded when the original JPG was created. The output is a lossless copy of the current JPG state.
JPG does not store transparency, so the white or coloured background from the JPG is preserved in the PNG. To make a background transparent you would need a separate background removal tool.
There is no hard server-side limit because conversion runs in your browser. Very large files (above 20 MB) may take a few seconds depending on your device's processing speed.
