PNG to JPG Converter Online Free
PNG files are sharp and support transparency, which makes them great for screenshots, logos and graphics — but they are often much larger than they need to be. This free PNG to JPG converter turns your PNG images into smaller JPG files right in your browser, with no upload, no sign-up and no watermark. JPG is the best choice for photos and screenshots you want to share by email, upload to a website, or attach to a form, because most sites and apps accept JPG everywhere. You choose the quality, from 0.5 to 1.0, and pick a white or black background for any transparent areas, since JPG cannot store transparency. The converted image keeps the exact same width and height in pixels — only the file format and the file size change.
PNG files only. The image is converted on your device and never uploaded.

Privacy: your images never leave your browser. Conversion runs entirely on your device.
How to Use
- Add your PNG file. Click the drop zone and choose a PNG image, or drag it straight from your computer into the box. The file name, size and dimensions appear in the list below.
- Set the quality. The slider defaults to 0.92, which keeps photos looking sharp while cutting the size. Drag it toward 0.5 for a much smaller file, or up to 1.0 for the highest quality.
- Choose a background colour. JPG has no transparency, so any see-through areas become the colour you pick. White suits most photos and documents; black suits dark graphics and logos.
- Click Convert to JPG and download. The tool draws your image onto a canvas, fills the background, and saves it as a JPG. Check the original and converted sizes, preview the result, then click Download JPG to save it.
Worked Example
Suppose you have a screenshot saved as a PNG that is 1200 pixels wide and 800 pixels tall, and the file is about 900 KB — too large to attach to an email with a 500 KB limit. Add the PNG, leave the quality at 0.92, choose a white background, and click Convert to JPG. The expected result is a JPG that is still exactly 1200 by 800 pixels, but only about 180 KB — roughly 80 percent smaller than the original PNG. The picture looks the same on screen, because a screenshot at quality 0.92 keeps its text and colours sharp, and it now fits easily under the email attachment limit. If the result is still too large, lower the quality to 0.8 and convert again; if you need the sharpest possible result, raise it to 1.0 and accept a larger file.
Why Convert PNG to JPG?
PNG stores every pixel without losing any detail, which is perfect for editing but wasteful for sharing. A photo saved as PNG can be three to five times larger than the same photo saved as JPG, because JPG compression removes fine detail the eye barely notices. That size difference matters: large PNGs are slow to upload, count against email attachment limits, and make web pages load slowly, which also hurts search rankings. JPG is accepted by almost every website, app, printer and form on the internet, so converting first avoids the "file type not supported" or "file too large" error later. Converting in your browser keeps the original private, too — nothing is uploaded, so screenshots containing passwords, messages or personal details never leave your device.
Tips for the Best JPG Result
Start at the default quality of 0.92 and only lower it if the file is still too big; below about 0.7 you may start to see blockiness in smooth areas such as skies. Pick the background colour before converting: white is the safe default for screenshots and documents, while black works better for a logo drawn in light colours on a transparent background. Keep your original PNG until you have checked the JPG, because JPG compression throws away detail and cannot be undone — you can always convert again at higher quality, but you cannot recover detail from a low-quality JPG. For photos and screenshots, JPG is the right choice; for a logo you still need to edit later, keep the PNG as your master copy.
Frequently Asked Questions
Is the PNG to JPG converter really free?
Yes. Converting PNG to JPG on this page is completely free, with no account, no sign-up and no watermark. You can convert as many images as you like, and the converted JPG belongs to you.
Are my PNG files uploaded to a server?
No. Your images never leave your browser. The conversion runs entirely on your device using the canvas built into your browser, so your pictures are never uploaded, stored or seen by anyone else.
Will converting to JPG reduce the quality?
Slightly, at most settings. JPG is a lossy format, so a tiny amount of fine detail is removed to shrink the file. At the default quality of 0.92 the difference is almost impossible to see on screen. Lower settings, such as 0.5, save more space but can show visible blockiness.
What happens to transparency in my PNG?
Transparent areas become the background colour you choose — white by default, or black if you select it. JPG has no transparency, so the see-through parts of your image are filled in. If you need to keep transparency, convert to PNG or WebP instead.
Which is smaller, JPG or PNG?
For photos and screenshots, JPG is almost always smaller — often 70 to 90 percent smaller than the same image as a PNG. PNG is only smaller for very simple graphics with large flat areas of one colour, and PNG is the better choice when you need transparency or pixel-perfect sharpness.
