What is JPG?
JPG (also written JPEG) is the most widely used photo format in the world. Created in 1992, it uses lossy compression that throws away detail the eye barely notices, which keeps photos small. Every phone, camera, browser, printer and upload form understands JPG, which is why government portals and job sites usually ask for it. The trade-off is that JPG has no transparency, and saving the same file again and again slowly lowers its quality.
What is PNG?
PNG is a lossless image format, so it keeps every pixel exactly as it is. It supports full transparency, which makes it the standard choice for logos, icons, screenshots and graphics with sharp text. Because nothing is thrown away, photos saved as PNG are usually much larger than the same photo as JPG or WEBP. PNG works in every browser, design tool and operating system.
When should you convert JPG to PNG?
- Logos and graphics with a transparent background
- Screenshots and images with text
- Images you plan to edit again in Photoshop, Canva or Figma
- Stickers and design assets
Tips for the best PNG results
- PNG files from photos are larger than the JPG. If you only need a smaller file, choose JPG or WEBP instead.
- You can convert many JPG files at once. They are processed one after another and can be downloaded together as a ZIP.
- Keep your original JPG files until you have checked the converted PNG images.
How JPG to PNG keeps your photos and images private
When you add a file to JPG to PNG, it is opened with your browser’s own engine, processed in memory and offered back to you as a download. ConvertKaro never receives a copy. This is why the tool is fast even on 4G, why there is no daily limit, and why it is safe for confidential photos and images like ID proofs, bank documents, contracts and family photos.

Frequently asked questions
Will converting JPG to PNG reduce quality?
PNG stores the image lossless, so no extra quality is lost during conversion. Any detail already removed by the original JPG compression cannot be restored, and the PNG file may be larger than the original.
Does PNG keep transparency from JPG?
JPG images do not have transparent areas, so there is nothing to lose. PNG can hold transparency if you edit the image later.
Can I convert multiple JPG files to PNG at once?
Yes. Select or drop as many JPG images as you like. Each one is converted separately, and you can download them all together as a ZIP file.
Is JPG to PNG really free?
Yes, completely free. You can use it as many times as you want, and every option on the page is included at no cost.
Is it safe to use JPG to PNG online?
