To convert PNG to JPG online, open our free Image Converter, drop your PNG, choose JPG as the output, and click Convert. Your file downloads in seconds, entirely in your browser — nothing is uploaded to any server.
Key Takeaways
- JPG's lossy compression makes photographic images much smaller than PNG's lossless approach — essential for email, upload forms, and web performance.
- Quality 85 is the recommended setting: dramatically smaller file, invisible quality loss for photos.
- JPG has no transparency support — a transparent PNG background turns white.
- Keep logos, icons, and diagrams as PNG; convert photographic images to JPG.
- All processing runs in your browser tab. Your files never leave your device.
Why Convert PNG to JPG?
Both formats display images, but they're built for very different jobs.
| Reason | Why JPG Wins |
|---|---|
| File size | JPG's lossy compression makes photographic files much smaller than PNG's lossless approach — actual savings depend on image complexity. |
| Email & forms | Most upload limits are 2 MB or 5 MB. JPG fits; PNG often doesn't. |
| Photo compatibility | Stock-photo sites, passport portals, job applications, and most CMSs expect JPG. |
| Faster web pages | Smaller images load faster, which improves Core Web Vitals and SEO. |
| WhatsApp & SMS | Both auto-compress — but JPG starts smaller, so quality holds up better after re-compression. |
JPEG is supported by every major browser and accepted by virtually every upload form, CMS, and content platform in use today. Upload a JPG almost anywhere and it works without negotiation.
Bottom line: PNG is built for graphics with sharp edges and transparency. JPG is built for photos with smooth gradients. Match the format to the content.

How to Convert PNG to JPG Online (3 Steps)
You don't need Photoshop, GIMP, or a desktop app. Our converter runs entirely in your browser — your file never leaves your device.
- Open the converter. Go to the Image Converter. No sign-up, no extension required.
- Drop your PNG. Drag and drop one or many PNG files, or click to browse. The tool auto-detects the input format.
- Pick JPG and download. Choose JPG as the output, set quality (85 is the recommended default), and click Convert. Your JPG downloads straight to your device.
The whole process takes under 10 seconds for a typical phone photo.
Privacy note: Conversion runs using JavaScript inside your browser tab. We never receive your file — there's nothing to store, log, or analyze on our end. See our privacy policy for the full picture.
Choosing the Right JPG Quality Setting
JPG uses lossy compression — it discards color detail your eye won't notice to shrink the file. Quality runs from 0 to 100, and higher isn't always better.
| Quality | When to Use | Approx. output size (4 MP photo PNG, estimated) |
|---|---|---|
| 95–100 | Print, archives, high-end portfolios | 1.5–2.5 MB |
| 85–90 | Recommended default for web and sharing | 350–700 KB |
| 75–80 | Email, social media, fast-loading galleries | 200–400 KB |
| 60–70 | Thumbnails, low-bandwidth previews | 100–200 KB |
| Below 60 | Avoid — visible blocky artifacts appear | — |
Estimates; actual output size depends on image complexity and content. Run your file through the converter to see the exact result.
Rule of thumb: Start at 85. If the file is still too large, drop to 75 before going lower. You almost never need 100 — the file grows substantially larger at quality 100 with almost no visible benefit. Google's own Lighthouse audit re-encodes images at quality 85 when estimating how much weight a page could save (Chrome Lighthouse docs), so 85 is a well-established, production-grade target.
If your converted JPG still exceeds an upload limit, run it through our Image Compressor for further size reduction without visible quality loss.
Watch Out: PNG Transparency Becomes White
JPG does not support transparency. When you convert a PNG with a transparent background, the converter fills those pixels with solid white (or whatever background color you choose).
This catches people out when they convert:
- Logos with no background → end up on a white square
- Stickers and product cutouts → get a white halo around the edges
- Screenshots with rounded corners → lose the curve, gain white triangles in each corner
If you need to keep the transparent background, don't convert to JPG. Your options:
| Situation | Recommended action |
|---|---|
| Need transparency + small file | Convert to WebP (supports alpha and compresses well) |
| Need transparency for logos / icons | Keep as PNG |
| Unwanted background to remove first | Use the Background Remover → then decide |
| Want a specific colored background | Add it before converting to JPG |
WebP is gaining ground — JPEG accounted for around 40% of all web images in 2022 (HTTP Archive Web Almanac, 2022) and had slipped to about 32% by 2024 (HTTP Archive Web Almanac, 2024) as modern formats gained share. But for broad compatibility and simple photo sharing, JPG remains the path of least resistance.
Common Mistakes to Avoid
1. Re-saving JPGs Multiple Times
Every JPG save is lossy. Don't convert PNG → JPG → JPG → JPG. Each pass adds artifacts. Always go from your original PNG to a single JPG export.
2. Using Quality 100 by Default
Quality 100 produces a JPG that's barely smaller than the PNG and visually identical to quality 92. Drop to 85 and you'll get a dramatically smaller file with zero perceptible difference.
3. Converting Logos and Icons
Logos with sharp edges, text, and flat color look fuzzy and blocky as JPG. Keep these as PNG (or SVG). JPG is built for photos, not graphics.
4. Forgetting to Resize First
A 6,000 × 4,000 px phone photo converted to JPG is still huge — even at quality 75. Resize before you convert. A 1,920-px-wide image is plenty for blogs, email, and most uploads. Use our free Image Resizer to scale down before exporting.
5. Using Converters That Upload Your Files
Many free PNG-to-JPG tools upload your file to their server, log it, and may use the data to train models or build ad profiles. Check the privacy policy before uploading personal photos. Better: use a client-side converter like ours — your file never leaves your browser.
Batch PNG to JPG: Converting Many Files at Once
Have a folder of PNG screenshots that all need to be JPG? Open the Image Converter and drop multiple files at once. The tool processes them in parallel and lets you download each converted JPG individually.
Tips for batch conversions:
- Use one quality setting (85 is a safe default) so file sizes stay consistent.
- Resize the batch first if they're all going to the same destination (e.g., a website gallery). Use the Image Resizer before converting.
- Sort by use case — photos go to JPG; logos and icons stay as PNG.
For very large libraries (hundreds of files), see our Bulk Image Compression Guide for workflows that pair conversion with compression.
When to Keep PNG Instead of Converting
Convert to JPG for: photos, screenshots of real-world scenes, complex artwork, anything you'll print or share at full size.
Keep as PNG for:
- Logos and brand assets with crisp edges and flat color
- Icons, UI screenshots, and product mockups
- Diagrams, charts, and infographics with text
- Anything that needs a transparent background
- Pixel art or images with very few distinct colors
When in doubt, look at the image. If it's photographic (smooth gradients, real light), JPG wins. If it has sharp edges and flat color regions, PNG wins.
Frequently Asked Questions
What's the difference between JPG and JPEG?
Nothing. JPG and JPEG are the same format — just different file extensions. Older Windows systems limited extensions to 3 characters, so JPEG became JPG. Either extension works; they open identically in every app.
Why is my converted JPG still too big?
The image is probably too large in dimensions. A 4,000-pixel-wide photo at quality 85 can still be 1–2 MB. Resize it first with our Image Resizer, then re-convert. You can also run the result through our Image Compressor for extra size savings without visible quality loss.
Does the PNG to JPG converter work on mobile?
Yes. The Image Converter runs entirely in your browser — no app installation needed. It works on iOS Safari, Chrome for Android, and all modern mobile browsers.
What happens to EXIF data when I convert PNG to JPG?
PNG files typically carry minimal metadata. The converted JPG will inherit any EXIF data present in the source file. If you want to strip location, device, and timestamp data from the output, run it through our free EXIF Viewer & Remover before sharing.
Can I choose a background color other than white when converting a transparent PNG?
Our converter currently fills transparent areas with white by default. To use a different background color, open the PNG in our Background Remover, select a color fill for the transparent area, then download and convert the result to JPG.
