PNG to JPG converter: free, fast and secure
Need to change an image from PNG to JPG? This tool does it instantly and for free, without uploading your pictures anywhere. JPG is accepted by every app, website and upload form, and it keeps photos small enough for WhatsApp, email and online applications. It also shrinks the file a lot, because JPG uses lossy compression that PNG does not.
Unlike most converters, ConvertKaro never uploads your images. The conversion happens on your own device, so it is quicker, there are no file limits, and your photos stay private.
How to convert PNG to JPG in 3 steps
- Add your PNG files. Tap “Select files” or drag and drop one or more .png images into the box above. You can also paste a screenshot with Ctrl+V.
- Adjust the options. Set the quality slider. Lower quality means a smaller JPG file.
- Download your JPG. Conversion starts instantly. Download each JPG file, or all of them at once as a ZIP.

PNG vs JPG: what is the difference?
Before converting, it helps to know how the two formats compare.

| Type | Raster, lossless | Raster, lossy |
| Compression | Lossless | Lossy |
| Transparency | Yes | No |

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.
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.
When should you convert PNG to JPG?
- Uploading photos to job, exam and government portals
- Sending pictures on WhatsApp and email
- Printing at a local photo shop
- Posting on Instagram, Facebook and marketplaces
Tips for the best JPG results
- For online forms with a size limit, use our Resize Image to 50KB or 20KB tool after converting.
- If your image has a transparent background, pick a background colour that matches where the image will be used.
- You can convert many PNG files at once. They are processed one after another and can be downloaded together as a ZIP.
- Keep your original PNG files until you have checked the converted JPG images.
How PNG to JPG keeps your photos and images private
When you add a file to PNG to JPG, 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 PNG to JPG reduce quality?
JPG uses lossy compression, so a tiny amount of detail is removed. With the quality slider at 90% (our default) the difference is practically invisible, and you can raise it to 100% if you need maximum quality.
Does JPG keep transparency from PNG?
JPG does not support transparency, so transparent areas are filled with a background colour. White is the default, and you can pick any colour before converting.
Can I convert multiple PNG files to JPG at once?
Yes. Select or drop as many PNG images as you like. Each one is converted separately, and you can download them all together as a ZIP file.
Is PNG to JPG 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 PNG to JPG online?
Yes. Your files are processed inside your own browser and are never uploaded to our servers, so nobody else can see them.

Yes, the tool is built mobile-first. Open this page on your phone, add your files and download the result directly.

There is no fixed limit set by us because files are not uploaded. Very large files depend on your device’s memory; most phones handle files of 100 MB or more without problems.

No. There is no watermark, no login and no email required. Your downloaded file is exactly your result.
