How to Convert PNG to JPG Online (Free, No Watermark)
You exported a screenshot or saved a photo and it came out as a PNG that's 5 megabytes. Converting it to JPG can take that to a couple hundred kilobytes with no visible difference — if it's the right kind of image. Here's when to convert, when not to, and how to do it privately in your browser.
Convert PNG to JPG in your browser
- Open the FreeCompressor image tool.
- Drop your PNG in.
- Set the output format to JPG.
- Pick a quality (80–90 is the sweet spot for photos) and Download.
No upload, no account, no watermark — the conversion runs locally with the canvas API, so your image stays on your device.
Why PNG photos are so big
PNG is a lossless format: it stores every pixel exactly. That's perfect for screenshots, logos and graphics with sharp edges and flat color. But photographs are full of subtle, continuous tonal variation — millions of slightly different colors — which is the worst case for PNG. The result is a file many times larger than it needs to be.
JPG was designed for exactly this: it's lossy, discarding detail your eye can't perceive, and it excels at photographs. A photo saved as PNG is routinely 5–10× larger than the same photo as a quality-85 JPG that looks identical.
When you should convert PNG → JPG
- Photographs and camera images saved or exported as PNG.
- Complex, colorful images with gradients and no sharp text.
- Anywhere you need a smaller file and the image has no transparency.
When you should NOT convert
- Transparency matters. JPG has no alpha channel; transparent areas get flattened onto a solid background (white, by default). Keep PNG, or convert to WebP, which stays small and preserves transparency.
- Screenshots, logos, UI, diagrams, text. JPG adds fuzzy “ringing” halos around sharp edges. PNG (or lossless WebP) keeps them crisp and is often smaller for these images anyway.
- You'll edit repeatedly. Every JPG save loses a little more; keep a lossless master and export JPGs from it.
What happens to transparency, exactly
When a transparent PNG becomes a JPG, every see-through pixel is composited onto a background color. If your logo had a transparent backdrop, it'll gain a white rectangle. If that's not what you want, the fix is simple: choose WebP instead of JPG. You get JPG-like file sizes with the transparency intact. Our PNG vs JPG vs WebP guide breaks down the trade-offs.
Quality settings: what to pick
- 90 — visually lossless; use when the photo is important.
- 80 — the classic default; great size-to-quality balance for the web.
- 60–70 — noticeably smaller, fine for thumbnails and previews.
Or skip the guessing entirely: use target-size mode to hit an exact KB limit and let the tool choose the quality.
