Convert PNG to JPG free
Turn PNG images into JPG — usually a much smaller file — right in your browser. Drop a batch, set the quality, and download. ToolCrix converts locally, so nothing is uploaded and there's no cap on how many images you process.
How to do it
- Add your PNG images above.
- JPG is preset as the output; set the quality (80% is the sweet spot for photos).
- Download each image or the whole batch as a ZIP.
Why PNG photos are so big
PNG is a lossless format: it stores every pixel exactly, which is ideal for screenshots and graphics but wasteful for photographs. A camera photo saved as PNG can be 5–10× larger than the same image as JPG, because JPG's lossy compression discards detail the eye can't distinguish. Converting a photographic PNG to JPG at 80% quality typically cuts the size by 70% or more with no visible difference — exactly what you want for websites, email attachments and form uploads with size limits. The batch converter applies one quality setting to every image, so a folder of phone-camera PNGs becomes web-ready JPGs in a single pass.
Transparency: the one thing you lose
JPG has no alpha channel. If your PNG has a transparent background — a logo, an icon, a cut-out product shot — those transparent areas will be flattened onto a solid background in the JPG. That's fine when the image sits on a matching background anyway, but if you need the transparency to survive, don't convert to JPG: use WebP instead, which supports transparency and compresses smaller (see the WebP converter).
When NOT to convert
Keep PNG for screenshots with small text, line art, charts and flat-color graphics — JPG's compression smears sharp edges into visible “ringing” artifacts around text, and for flat graphics PNG is often smaller than JPG anyway. Also avoid converting an image you plan to keep editing: each JPG re-save loses a little more detail, so archive the PNG master and export JPG copies for sharing. In short: photos travel as JPG, graphics and works-in-progress stay PNG.
Frequently asked questions
What happens to a transparent background? JPG can't store transparency, so ToolCrix flattens transparent PNG areas onto a solid background — if you need transparency kept, convert to WebP instead.
What quality setting should I use? 80% is the ToolCrix default sweet spot — visually identical to the original photo at a fraction of the size; drop to 60–70% only when hitting strict upload limits.
Can I convert many PNGs at once? Yes — ToolCrix converts whole batches in your browser and bundles the results into a single ZIP download.
Why did my screenshot look worse as JPG? JPG compression blurs sharp edges, so text-heavy screenshots show artifacts — ToolCrix's advice is to leave screenshots and line art as PNG, where they're both sharper and often smaller.
Are my images uploaded during conversion? No — the ToolCrix converter runs entirely in your browser, so private photos never leave your device.
