Is this JPG to PNG converter really free?

Yes. There is no account, no daily limit, no watermark and no paid tier. Convert as many JPG files as you like.

Do my JPG files get uploaded anywhere?

No. The conversion runs entirely in your browser with the Canvas API and WebAssembly codecs. Nothing about your file is sent to us, so there is nothing for us to keep.

Will converting JPG to PNG reduce quality?

PNG is lossless, so the pixels that survive the decode are written exactly as they are. Nothing further is discarded during the conversion.

Can I convert several JPG files at once?

Yes. Drop the whole batch in, convert them together, then download them individually or as one ZIP file.

Does it work on my phone?

Yes — the tool works in any modern mobile or desktop browser. Very large files can strain a phone's memory, so the per-file limit is 50 MB.

PNG is lossless and supports transparency, which makes it the right container when you are about to edit a JPG repeatedly or need to cut a background out without compounding compression damage.

How to convert JPG to PNG

Drag your JPG files onto the box above, or click Choose files to browse. Multiple files at once are fine.
PNG is already selected as the output. Adjust quality (not applicable — this target is lossless) or turn on resizing if you need a specific pixel width.
Press Convert, then download each result or take the whole batch as a ZIP.

About the JPG format

The universal photographic format. Small files, lossy compression, no transparency — supported by every device and every piece of software ever made.

About the PNG format

Lossless compression with full alpha transparency. The right choice for logos, screenshots, diagrams and any graphic with sharp edges or flat colour.

Why convert in the browser?

Most online converters upload your file, process it on a rented server and promise to delete it later. That promise is unverifiable, and it puts your photographs, scans and screenshots on somebody else’s hardware. This tool takes the other approach: the conversion code is downloaded to you and runs locally, so the file stays on your device from start to finish. You can confirm it yourself — open your browser’s developer tools, watch the Network tab, and convert a file.
