How do I convert a JPG to PNG with this tool?

Drag and drop your JPG onto the page (or click to browse) and it is decoded locally in your browser. Then click Export — PNG is already pre-selected as the output format — and download the lossless PNG. It's completely free, runs entirely in your browser with no upload, and your original file stays untouched.

Does converting JPG to PNG improve quality?

No. PNG stores the decoded pixels losslessly, so no further quality is lost — but detail already discarded by JPEG compression cannot be recovered.

Why is my PNG larger than the original JPG?

PNG is lossless and photographic content compresses poorly without loss, so a PNG of a photo is often 5–10× larger than the JPEG. That is expected.

When should I use PNG instead of JPG?

When a workflow requires PNG input, when you plan repeated lossless edits, or for graphics with sharp edges, text, or transparency.

Are images uploaded to a server?

No. The conversion runs entirely in your browser using the Canvas API; your images never leave your device.

Is converting JPG to PNG free?

Yes — converting JPG images to lossless PNG is completely free, forever. No account, no sign-up, and no limit on how many files you convert. The Canvas API decodes the JPG and re-encodes it as PNG entirely in your browser; your images are never sent to any server. The site is ad-supported.

Does it work offline?

Yes. After the page loads, the conversion needs no server connection.

What formats are supported?

Input: JPEG, PNG, WebP, and AVIF (any of these can be loaded). Output: JPEG, PNG, or WebP — AVIF output is not supported by browsers.

Is there a file size limit?

No artificial limit. The practical limit is your device’s available memory (typically tens of MB or more). Very large images may take longer to convert.
