Why convert PNG to JPG?
PNG is the right format for screenshots, app exports, and any image with text or sharp edges — but PNG files are typically 3–10× larger than the JPG equivalent. When you ship product photos to an e-commerce listing, attach screenshots to a Jira ticket, or load images into a CMS, that bulk turns into slow uploads and storage bills.
JPG (JPEG) trades lossless compression for far smaller files using DCT compression. At quality 85 the difference is invisible to the eye on natural images, while a 4 MB screenshot routinely drops to 300–500 KB. JPG is also the universally supported format — every browser, email client, photo viewer and old phone reads it without a plugin.
File Converter Pro runs the PNG → JPG conversion entirely on your Windows PC. No file is uploaded to a server, no log is written to a cloud bucket, no watermark is added, and there's no daily task limit. The same engine handles a single 30 MB poster export and a folder of 5,000 thumbnails.
How to convert PNG to JPG on Windows
- Install File Converter Pro. Open the Microsoft Store, search for File Converter Pro, and install. The free trial unlocks the full PNG → JPG converter so you can test before paying €6.49 once.
- Drag your PNG files into the app. Drop one file, a multi-select, or an entire folder. Files of any size are accepted — the queue handles 4K screenshots, exported design boards and album covers in the same run.
- Pick JPG as the output format. Choose JPG in the output panel. Set the quality slider (70–95% works for nearly every workflow), and pick a background color to replace PNG transparency (white is the default).
- Click Convert. Files are processed locally on your CPU. Output JPGs are saved next to the originals or to a folder you specify. A 100-file batch typically finishes in under 30 seconds on a 2020 laptop.
Batch conversion for big folders
Photographers, designers and marketers usually deal with PNG folders, not single files. File Converter Pro is built around the queue: drop a directory, and every PNG inside (including subfolders, if you opt in) is added in one shot.
- Process thousands of PNGs in a single run with no per-task cap.
- Preserve the original folder structure on output, or flatten it.
- Skip files that already exist at the destination, or overwrite — your call.
- Pause and resume the queue without losing the already-finished conversions.
Quality settings that actually matter
The biggest mistake people make with PNG → JPG is leaving the quality at 100% — which kills the size benefit — or dropping it to 50% and getting visible artifacts. A few rules of thumb:
- Quality 90–95: print, archive, e-commerce hero images. Visually indistinguishable from the source.
- Quality 80–85: web product images, social posts, blog thumbnails. The sweet spot.
- Quality 70–75: messaging apps, chat attachments, low-bandwidth galleries.
- Below 70: only when bandwidth is the absolute hard limit.
File Converter Pro also lets you set chroma subsampling (4:4:4 keeps reds sharp on text-heavy screenshots) and progressive JPG (better for slow connections). These knobs cover most professional workflows that web tools hide entirely.
Common issues and fixes
- Transparent areas turn black. JPG does not support transparency. Set the background color in the output panel — white is most common, but pick the brand color if you're exporting for a deck.
- Text on screenshots looks blurry. Increase quality to 92 or higher and switch chroma subsampling to 4:4:4. JPG was designed for photos, so very crisp text needs the extra precision.
- Output is bigger than the PNG. Tiny icons or pure-color graphics can compress better as PNG. The app warns you when JPG is larger and offers to skip those files.

FAQ
Can I convert PNG to JPG offline on Windows?
Yes. File Converter Pro converts PNG to JPG fully offline on Windows 10 and 11. Files never leave your computer — no upload, no cloud, no telemetry on file contents.
How does PNG to JPG conversion handle transparency?
JPG does not support transparency. File Converter Pro flattens transparent pixels onto a background color you choose (white by default). The result is a fully opaque JPG that opens in any viewer.
How small will my JPG files be compared to the original PNG?
For typical screenshots and photos, JPG output at quality 85 is 60–90% smaller than the source PNG. A 4 MB PNG screenshot usually drops to 300–500 KB without visible quality loss.
Is there a limit on how many PNGs I can convert at once?
No. The free trial and the €6.49 one-time license both support unlimited batch conversion. Drop a folder with thousands of PNGs and File Converter Pro queues them all.
