Sometimes JPG is the wrong format for the job: design tools, presentations and image editors often work better with PNG, a lossless format that keeps edges crisp and supports transparency. This converter goes beyond a plain format swap — you can set the output resolution, switch background transparency on or off, and choose the compression level, then compare the original and converted previews side by side before downloading.
Everything runs in your browser, so your images stay on your device — nothing is uploaded to a server. Designers use it to prepare graphics for editing and web work, and anyone can use it when a platform or document simply asks for a PNG. Free, with no sign-up and no watermark.
PNG is lossless and supports transparency, so it suits graphics, logos and images you plan to edit further, and some platforms require PNG uploads.
The PNG keeps every pixel of your JPG exactly — PNG itself adds no further quality loss when you save or edit it again.
Output resolution sets the image size, background transparency can be switched on or off, and compression level (None, Medium or High) trades file size against saving speed.
Yes — conversion happens in your browser with no uploads, no sign-up and no cost.
