About This JPG to PNG Converter
This free JPG to PNG converter transforms your JPEG images into lossless PNG files directly in your browser. No files are uploaded to any server — the HTML5 Canvas API processes the image on your device, keeping your photos completely private.
PNG (Portable Network Graphics) uses lossless compression, which means every pixel is stored exactly as it appears. Unlike JPG, PNG does not introduce compression artifacts. Converting from JPG to PNG preserves the exact pixels in the source file without adding any further quality loss.
The converted PNG file will typically be larger than the original JPG because PNG must store all pixel data without discarding any information. This is the expected trade-off when switching from a lossy to a lossless format.

Frequently Asked Questions
Will converting JPG to PNG improve image quality?
No — PNG is a lossless format but it cannot recover detail that was lost when the original JPG was compressed. The PNG output preserves the exact pixels in the JPG without adding further quality loss, but it will not be sharper or cleaner than the source file.
Does JPG to PNG conversion support transparency?
JPG files do not contain transparency information, so the resulting PNG will have no transparent areas. If you need a PNG with a transparent background you would need to remove the background manually in an image editor after conversion.
Why does the PNG file become larger than the original JPG?
PNG uses lossless compression while JPG discards some image data to achieve smaller file sizes. A PNG must store every pixel exactly, so it is always larger than the equivalent JPG. This size increase is normal and expected when converting to a lossless format.
Is the conversion itself lossless?
Yes. The JPG-to-PNG conversion itself introduces no additional quality loss. The PNG output is a lossless representation of the exact pixels in your JPG. No new compression artifacts are introduced.
Can I convert a JPG to PNG without losing quality?
You can prevent any further loss — converting to PNG adds no new compression artifacts. However, quality loss that occurred when the JPG was originally saved (such as blurring and colour artifacts) cannot be undone by converting to PNG.
Are my images uploaded to a server?
No. This tool uses the HTML5 Canvas API entirely inside your browser. Your images never leave your device and are never sent to any server. The conversion happens locally and privately with no internet connection needed after the page loads.
What JPG files does this tool support?
This tool supports standard JPG and JPEG files, including photos from digital cameras, smartphones, and web images. Files with the .jpg or .jpeg extension are accepted. The maximum file size is limited only by your browser and device memory, typically several hundred megabytes.
