About the PNG to JPG Converter

The ByteTools PNG to JPG Converter turns any PNG image into a much smaller JPG file. Pick the JPEG quality with a slider and watch the estimated file size update live, so you can balance sharpness against size before you download. Typical photos shrink by 60–90% compared with the original PNG.

Because JPG does not support transparency, you choose a matte color — white by default — and any see-through areas of the PNG are filled with it during conversion. That makes the tool ideal for preparing logos, screenshots and graphics for email, websites, forms and documents that demand JPG.

Everything runs 100% locally in your browser using the canvas API. Your image is never uploaded to a server, so private screenshots and design files stay on your device.

Frequently asked questions

Why is a JPG so much smaller than the same PNG?

PNG is a lossless format, so it stores every pixel exactly and photos become huge. JPG uses lossy compression tuned for photographic detail, which usually shrinks a photo to a tenth of the PNG size with little visible difference at quality 80–90.

What happens to transparency when converting PNG to JPG?

JPG has no alpha channel, so transparent pixels must be filled with a solid color. This tool lets you choose that matte color before converting — white is the safest default for documents, but you can match your page background instead.

What JPEG quality setting should I use?

Quality 80–90 is the sweet spot for most photos: files get dramatically smaller while artifacts stay invisible at normal viewing sizes. Drop to 60–70 for web thumbnails, and use 95 only when a pixel-peeping client demands it.

Does converting PNG to JPG lose quality?

Yes, slightly — JPEG is lossy, so fine detail such as sharp text edges can pick up faint artifacts. For photos the loss is rarely visible, but for screenshots with small text keep the quality above 85 or stay with PNG.

Is it safe to convert confidential images here?

Yes. The conversion happens entirely in your browser with JavaScript and the canvas API. The file is never uploaded, so sensitive screenshots, IDs and design mockups never leave your computer.
