About This PNG to JPG Converter
This free PNG to JPG converter changes your PNG images into JPEG files instantly in your browser. No files are uploaded — the conversion uses the HTML5 Canvas API locally on your device, keeping your images completely private.
JPEG uses lossy compression, which means some image data is discarded to achieve smaller file sizes. You control the quality with the slider — higher quality preserves more detail but produces a larger file. At 85% quality, most images are visually indistinguishable from the original while being significantly smaller than the PNG.
PNG supports transparent backgrounds; JPG does not. This tool automatically fills any transparent areas with white before converting. If you need a different background colour, edit the image in a graphics application first.
How to Convert PNG to JPG
Step 1 — Click "Choose PNG" or drag your PNG file onto the upload area above.
Step 2 — Adjust the quality slider. 85% is recommended for most images.
Step 3 — Click "Convert to JPG". Transparent areas are filled white automatically.
Step 4 — Download the JPG and click "Convert Another" if you need to process more files.
When to Use JPG Instead of PNG
- Photographs and realistic images where transparency is not needed
- Web images where file size directly affects page load speed
- Email attachments where file size limits apply
- Social media uploads that will be re-compressed anyway

Frequently Asked Questions
Will converting PNG to JPG lose quality?
Yes — JPG uses lossy compression so some image detail is discarded. The amount of quality loss depends on the quality setting. At 85% quality most images look virtually identical to the original. Lower quality settings produce smaller files with more visible compression artifacts such as blurring around edges.
What happens to transparent pixels when converting PNG to JPG?
JPG does not support transparency. This tool fills all transparent areas with a white background before conversion. This is the standard approach and ensures the resulting JPG displays correctly in all browsers and applications.
What quality setting should I use?
For most images, 80–85% quality gives an excellent balance between file size and visual quality. Use 90–95% for professional or print images where quality is critical. Use 60–75% for thumbnails or web images where a smaller file size is the priority.
Why is my JPG file smaller than the original PNG?
JPG uses lossy compression that discards some image data to achieve smaller file sizes. PNG stores every pixel exactly and is always larger for photographic content. For a typical photograph, the JPG output can be 5–10 times smaller than the equivalent PNG.
Can I convert a PNG with transparency to JPG?
Yes. This tool handles transparent PNG files by filling the transparent areas with white before converting to JPG. If you need a different background colour — such as black or a brand colour — you would need to edit the image in a graphics application first.
Is PNG to JPG conversion reversible?
Not perfectly. Once a PNG is converted to JPG the compression artifacts are permanent. Converting the resulting JPG back to PNG gives you a lossless file, but the compression artifacts from the JPG step remain — it will not restore the original PNG quality.
Are my images sent to a server?
No. All conversion happens locally in your browser using the HTML5 Canvas API. Your PNG files never leave your device and are never uploaded to any server. The tool works entirely client-side and needs no internet connection after the page loads.
