About this tool
PNG to JPG Converter
PNG is the format of choice for screenshots, logos, and anything that needs crisp edges or transparency — but that precision makes it a heavyweight. Photographs and detailed images saved as PNG balloon to many times the size of the equivalent JPG, and plenty of upload forms, email clients, and storage limits punish you for it. This converter re-encodes your PNG as a compact JPG entirely on your own device, so you get a smaller, universally accepted file without handing your image to a website.
Why convert PNG to JPG?
- Much smaller files — for photographs, JPG can be a fraction of the PNG size with no visible difference, making uploads and email attachments painless.
- Beats upload limits — when a form complains your image is too big, dropping from PNG to JPG is often the quickest fix.
- Still opens everywhere — JPG is as universal as PNG, so nothing about compatibility is lost in the trade.
The transparency caveat
PNG can store transparent pixels; JPG cannot. When this tool meets a transparent region it fills it with white before encoding, because a flat white background is what documents, slideshows, and photo apps expect. That decision is permanent in the resulting JPG, so if transparency matters for your image — say, a logo meant to sit on a coloured page — keep it as a PNG instead.
Why it’s private
Everything happens in your browser. When you pick a file, the browser’s own image pipeline decodes the PNG and re-encodes it as a JPG on your machine. Nothing is uploaded, nothing is stored, and nothing is logged. That makes it safe for screenshots of private dashboards, scanned paperwork, or any image you’d rather not send to a server.
Tips for the best result
- Quality slider: 80% is the sweet spot for photos. Push toward 100% to edit or print, or lower it to shrink the file for the web.
- Keep logos and text as PNG: JPG softens sharp edges, so line art and screenshots usually look better left alone.
- Large images are fine: because the work runs locally, the only real limit is your device’s memory, not an upload cap.
