Why Convert PNG to JPG? File Size, Speed & Compatibility
PNG is the go-to format for lossless quality — logos, screenshots, graphics, and images that need pixel-perfect accuracy. But for photographs and images where lossless quality isn't required, PNG files are often dramatically larger than necessary. A photograph saved as PNG can be 5–10× larger than the same photo saved as JPG at 90% quality, with no visible difference to the eye.
Converting PNG photos to JPG reduces file sizes by up to 80%, making images faster to email, upload, and load on websites. If you have a collection of PNG photos — screenshots converted to PNG, images exported from design tools, or photos you received as PNG — this tool converts them all to smaller, more shareable JPG files in seconds.
The Transparency Problem — and How We Solve It
JPG has no support for transparency. PNG does. This is the most important technical difference between the two formats, and it's why PNG to JPG conversion requires an extra step that most simple converters get wrong.
When you convert a PNG with a transparent background to JPG, the transparent area has to become something — typically a solid colour. Most tools default to black, which destroys logos and icons with dark text. This tool gives you a background colour picker — choose white (most common), black, light grey, or any custom colour. Your transparent backgrounds are filled correctly before conversion, giving you a clean JPG every time.
PNG vs JPG — When to Use Each
| Format | File size | Quality | Transparency | Best for |
|---|---|---|---|---|
| PNG | Large | Lossless (perfect) | Yes | Logos, graphics, screenshots, editing |
| JPG | Small | Very good (lossy) | No | Photos, social media, web, email |
Keep as PNG when transparency matters, when you'll edit the image further, or when it's a graphic with sharp edges (logo, icon, illustration). Convert to JPG when it's a photograph, when file size matters for sharing or web publishing, or when the image doesn't need transparency.
Understanding the Quality Slider
JPG uses lossy compression — a quality setting controls the trade-off between file size and image quality:
- 90% (recommended) — visually lossless in virtually all cases. Ideal for photos you'll share, print, or publish online. Roughly 3–5× smaller than PNG at this quality.
- 80–85% — further size reduction with minor quality loss in very detailed areas. Good for website thumbnails and social media images.
- 70–75% — significant compression, visible artefacts in complex areas. Suitable only for small preview images or heavy bandwidth constraints.
- 100% — maximum quality, but still lossy. File size approaches PNG without the lossless guarantee. Rarely worth choosing over 90%.
How to Convert PNG to JPG on Windows
Windows has basic built-in PNG to JPG conversion (via Paint or Photos app), but neither gives you quality control or batch support. This browser-based tool does both:
- Open this page in Chrome, Edge, or Firefox on your Windows PC
- Set your JPG quality and background colour
- Click "Browse / Select Files" and choose your PNG images
- Download your JPG files — open in any Windows app instantly
How to Reduce PNG File Size for Websites
If you're uploading PNG screenshots or images to a WordPress site, blog, or e-commerce store, converting to JPG can dramatically improve your page speed scores. PNG photos on websites are one of the most common causes of slow Largest Contentful Paint (LCP) scores — a Core Web Vitals metric that Google uses as a ranking factor.
- Convert PNG photos to JPG at 85% quality before uploading to WordPress
- For even smaller files, convert to WebP using our WebP converter — WebP is 25–35% smaller than JPG
- Only keep PNG format for logos, icons, and graphics that need transparency

Frequently Asked Questions
How do I convert PNG to JPG for free?
Drop your PNG files into this tool or click Browse to select them. Set your quality level and background colour for transparent PNGs, then the conversion runs instantly in your browser at no cost. No signup, no software, no file size limit.
What happens to PNG transparency when converting to JPG?
JPG does not support transparency, so transparent areas must be filled with a solid colour before converting. This tool lets you choose: white (default), black, light grey, or any custom colour. Select the background that matches your use case before uploading. If your PNGs don't have transparency, this setting has no effect.
Will converting PNG to JPG reduce quality?
JPG is a lossy format, so there is a minor quality trade-off. At 90% quality (our default), the difference is invisible to the naked eye for photographs. For graphics, logos, and screenshots with sharp edges, you may notice slight compression artefacts at very high zoom — keep these as PNG if lossless quality is required.
Are my PNG files uploaded to a server?
No. Conversion uses your browser's built-in Canvas API — a native browser feature. Your files never leave your device and are never sent to any server. This is a technical design choice, not just a policy.
Why convert PNG to JPG?
PNG files are often much larger than JPG at the same visual quality. Converting photos from PNG to JPG can reduce file size by 50–80%, making images faster to share by email, upload to websites, and load on web pages. If the image doesn't need transparency and isn't a graphic with sharp edges, JPG is almost always the better choice for size.
Can I convert multiple PNG files to JPG at once?
Yes. Drop as many PNG files as you want at once. Each is converted individually in your browser. Download one by one or use "Download All" to get every JPG at once. No file count or size limits.
What is the difference between PNG and JPG?
PNG uses lossless compression — perfect quality but larger files. Best for logos, graphics, and screenshots where sharp edges matter. JPG uses lossy compression — smaller files with minor quality reduction. Best for photographs you'll share or publish online. PNG supports transparency, JPG does not.
Does this PNG to JPG converter work on iPhone and Android?
Yes. Works on Safari (iPhone/iPad), Chrome (Android), and all desktop browsers on Windows and Mac. No app or software download required on any device.
