PNG to JPG Converter

Turn PNG images into smaller JPG files — free, in your browser, no uploads.

Processed locally – files never leave your device

Drop PNG images here or click to browse

PNG files only · up to 50 MB each · add several at once · or paste with Ctrl+V

JPG has no transparency, so see-through areas are filled with the background colour above. Quality and colour apply when files convert — changing them re-converts files already added.

    Next: try JPG to WebP Converter — Convert JPG images to WebP format, single or batch, without uploading.

    PNG files are big. They store every pixel exactly, which suits screenshots and graphics — but a single PNG photo can be several megabytes, too heavy to email or upload. This free PNG to JPG converter shrinks your images in seconds, right in your browser, without uploading them anywhere.

    Drop in one PNG or a whole batch, pick a quality level, and download JPGs typically 50–80% smaller. If your PNG has a transparent background, choose a fill colour first — JPG cannot store transparency. For even smaller files, try the Image Compressor or the JPG to WebP Converter.

    How to use

    1. Drop PNG files onto the box above, click it to browse, or paste an image with Ctrl+V. You can add several files at once.
    2. Set the JPG quality — 92% is a good balance — and pick a background colour for transparent areas.
    3. Wait a moment while each file converts. Before and after sizes are shown for every file, with the percentage saved.
    4. Download files one by one, or grab them all at once with Download all (ZIP). Use Start over to convert a new batch.

    Why use Toolsvine

    Most converters upload your images to a server, where they sit in someone else's storage. Toolsvine converts locally, so screenshots, client work and personal photos never leave your device. It is free, needs no account, and works offline once the page has loaded.

    PNG vs JPG: what's the difference?

    PNG is lossless: it keeps every pixel exactly, and it supports transparency — the right choice for screenshots, logos and diagrams. The price is file size: a PNG photo is often three to ten times larger than the same image as a JPG.

    JPG is lossy: it throws away detail the eye barely notices, especially in smooth areas like skies and skin. At quality 90 or above, most people cannot tell a JPG from the original PNG. JPG cannot store transparency at all, so this tool fills see-through pixels with your chosen background colour — white by default.

    What happens to transparency?

    If your PNG has a transparent background, the JPG shows that area in the background colour you picked. White suits most uses, but match the page colour if the image will sit on a coloured web page.

    How much smaller will my JPG be?

    A PNG photograph usually shrinks by 60–90% at quality 92. A screenshot with flat colours shrinks less, around 30–50%, and text can look slightly soft at low quality — keep quality above 85 for screenshots. Very small images sometimes barely shrink at all; this tool shows the real before-and-after size for every file.

    Frequently asked questions

    Will converting PNG to JPG reduce quality?

    Slightly — JPG is lossy, so a tiny amount of detail is discarded. At quality 90–95 the difference is invisible on screen for most photos. Below 75, visible blockiness appears, especially in smooth gradients.

    What happens to my PNG's transparent background?

    JPG cannot store transparency, so see-through areas are filled with the background colour you choose — white by default. Match a coloured background so edges blend. If transparency must be kept, keep the PNG.

    Can I convert several PNGs at once?

    Yes. Drop in as many PNGs as you like and they convert one after another, each with its own before-and-after size. When they are all done, Download all (ZIP) saves every JPG in a single zip file.

    Is there a file size limit?

    Files up to 50 MB each are accepted. Very large PNGs take longer and use more memory. If a file is rejected, try a smaller one or resize it first with the <a href="/image-resizer/">Image Resizer</a>.

    Why is my JPG bigger than the original PNG?

    It happens with very small or simple images — a tiny icon or a mostly-white diagram. PNG compresses flat colours extremely well, while JPG adds overhead. If a JPG comes out bigger, just keep the original PNG.
