How to convert PNG to JPG
- Drag your PNG files into the box, or choose Browse files.
- Set the quality. Higher numbers keep more detail but make larger files.
- Choose a background colour if your PNG has transparent areas.
- Select Convert images and download your JPG files.
Why convert PNG to JPG
PNG files from screenshots and design tools can be very large. Converting a photo-like PNG to JPG often reduces its size a great deal, which helps pages load faster and makes files easier to email or upload to sites with size limits.
Choosing the right JPG quality
- 90 to 100%: very close to the original, larger files.
- 75 to 85%: a good balance for websites and sharing.
- Below 60%: small files, but visible blockiness can appear.
Private and free
The conversion happens in your browser. Your images are not uploaded to ImgNexa, and there is no account or watermark.
When to keep the PNG
How much a PNG shrinks depends on the image. A photograph may shrink a lot. A flat graphic with large solid areas and sharp text can look worse as a JPG and may not get much smaller, because PNG already stores flat colour efficiently.
- Keep PNG for logos, icons, diagrams and screenshots full of text.
- Keep PNG when you need transparency or plan to edit the image again.
- Choose JPG for photographs that only need to be viewed, shared or uploaded.
Transparency and backgrounds
JPG cannot store transparency, so any transparent area in your PNG has to become a solid colour. ImgNexa fills those areas with the background colour you choose, white by default. Pick a colour that matches the page or design where the image will be used. If you need to keep transparency, stay with PNG, or use WebP.
Getting the best result
- Start with the highest quality PNG you have. Compression cannot add detail back later.
- Use 80 to 90% quality for photos you will show large, and 65 to 80% for small web images.
- Avoid converting the same JPG again and again. Each save loses a little more detail.
- Check text and thin lines at full size, since they show compression artifacts first.
Which quality setting should you pick?
The quality slider trades file size against detail. Around 90 keeps photos looking almost identical to the original while still cutting the size noticeably. Between 75 and 85 is a good range for pictures that will be shown on web pages, where smaller files load faster. Below 60, blocky patches and fuzzy edges start to appear, especially around text.
Screenshots with a lot of small text do not compress as well as photographs, so keep the quality high for those or leave them as PNG. If you are converting a picture that has transparent areas, choose the background colour first, because JPG cannot store transparency and the empty areas have to be filled with something.
Frequently asked questions
What happens to transparent areas?
JPG cannot store transparency, so transparent areas are filled with the background colour you pick. White is the default.
Will I lose quality?
JPG is a lossy format, so some detail is discarded. At high quality settings the difference is usually hard to see.
Which quality setting should I use?
Around 80 to 90% works well for most photos. Lower it if you need a smaller file.
Is image metadata kept?
No. The image is redrawn in your browser, so camera and location metadata is not carried into the new file.
Are my images uploaded to a server?
No. Everything runs in your browser and your files stay on your device.
Will my PNG get smaller?
Photo-like PNG files often get much smaller as JPG. Simple graphics may not, because PNG already compresses flat colours well.
Can I convert several PNG files at once?
Yes. Add up to 20 PNG files, convert them together and download them one by one or as a single ZIP.
Which background colour should I choose?
White suits most pictures and documents. Pick a dark colour if the image will be shown on a dark page, so that soft edges do not show a pale halo.
