This JPG to PNG converter re-saves a JPG as a lossless PNG without uploading anything. Drop the file, press one button, download the PNG — the conversion happens in your browser.
There are no quality settings because none are needed: PNG is lossless, so the pixels from your JPG are stored exactly as decoded. What changes is the container — and with it, compatibility with tools that demand PNG.

When a PNG Copy of a JPG Is the Right Move
Converting JPG to PNG does not improve the image — the compression artifacts baked into the JPG stay. What it does is change the rules going forward. Many uploaders insist on PNG: design tools, logo submissions, some government and job portals, and every context where further editing is expected. A PNG copy also survives future edits better, because re-saving a PNG never degrades it, while every re-save of a JPG re-compresses it.
The honest expectation on file size: the PNG will usually be larger than the JPG, often several times larger for photographs. That is not a bug — PNG stores every pixel losslessly, and photographs are exactly what JPG was invented to compress. For screenshots, flat graphics, text and logos, the difference is much smaller, and PNG is frequently the better long-term format for them anyway.
The conversion itself is a decode-and-encode that runs on your device. The browser decodes the JPG into raw pixels, re-encodes those pixels as PNG, and hands you the file — no server sees the image at any point, and there is no upload or download round-trip for the source file, which makes the whole thing faster than most online converters even before you count the privacy benefit.
If your actual goal is a smaller file rather than a different format, the better route is JPG to WebP — WebP keeps the size advantage of JPG and usually beats it.
Frequently Asked Questions
No — the compression already baked into the JPG stays. PNG preserves whatever it receives without adding new loss, which is exactly why it is the right format for further editing.
PNG stores every pixel losslessly and photos compress poorly in it. For photos this is normal. For screenshots and flat graphics the size difference is small.
No — JPG has no transparency to preserve, so the PNG is fully opaque with a white background already baked in.
No. The decode and re-encode happen in your browser. You can disconnect from the internet after the page loads.
One at a time here, but as often as you like — there is no daily limit and no signup.
Yes. Safari on iPhone and Chrome on Android both handle it; the download saves through the normal share or Downloads flow.
