PNG to JPG Converter: Shrink Big PNG Files with Convertavo
Your phone saves every screenshot as a PNG, and those files pile up fast. Convertavo's free PNG to JPG converter turns them into much smaller JPGs that look the same. In our example, a 596 KB screenshot came out at 162 KB. Add one file or a whole folder, and it usually takes 2 to 6 seconds.

What the PNG to JPG tool does
Much smaller files
Our example screenshot went from 596 KB to 162 KB, and looked the same.
You pick the background
See-through parts turn white, black, or any colour you type in.
A whole folder at once
Up to 100 files in one go on the biggest plan, all with the same settings.
Why is my PNG file so big?
A PNG holds on to every single pixel. That's fine for a logo, but it makes photos and busy screenshots heavy.
We saved one 1080 × 2340 phone screenshot both ways to show the gap. As a PNG it was 596 KB. The JPG copy, at quality 85, came to 162 KB. Side by side on the screen, we couldn't pick which was which.
JPG, which some apps call JPEG, saves space by leaving out tiny details your eye wouldn't catch anyway. And since phones save every screenshot as a PNG, converting a folder of them can clear quite a bit of room.
What happens to a transparent background?
JPG can't do see-through, so any transparent part of the PNG has to become a solid colour. Background for transparency decides which. White suits documents and most websites, and black suits dark designs. With Custom colour you type the colour of your own background, like #F5E6CC, and the image blends into it.
Why does my logo have a white box around it now?
We ran a test PNG with a see-through half through the converter. Left on the default, that half came out white. With #F5E6CC typed into Custom colour, the same half came out that beige instead. So for a logo on a coloured website, we'd put the site's own colour code in there, or just keep the logo as a PNG.
When should I keep a file as PNG?
Photos, and screenshots of photos, are the ones we convert to JPG. Logos, icons, diagrams and anything with a see-through background stay PNG. A screenshot of a web page or an app usually looks the same as a JPG at quality 85.
The reason is edges. JPG handles a photo well but struggles with a sharp line, so a logo turned into a JPG picks up faint, blurry halos around the letters. The picture below is zoomed in on a real conversion at quality 82.
Will the JPG look worse than the PNG?
Not at the right setting. For photos we'd use a quality between 85 and 92. At normal size you won't see a difference from the PNG, and the file still shrinks a lot.
Optimise for the web squeezes out a little more without touching the picture. It saves the JPG as a progressive file with better compression tables, so only the size changes.
If the image is wider than you need, type a number into Max width. A 400-pixel-wide test PNG came back 200 pixels wide when we set it to 200. Left on Original, the size doesn't change.
Can I convert lots of PNG files at once?
Yes. Add a whole folder of screenshots or exports, and they're converted together. How many go in at once depends on your account: 3 if you're not signed in, 10 with a free account, and up to 100 on the biggest plan.
Every file costs 1 credit, out of the 20 you get free each day. Strip metadata starts switched on, so whatever extra info was tucked inside the PNGs doesn't make it into the JPGs.
Is Convertavo's PNG converter free and safe?
Is it free?
Yes. You get 20 free credits every day, which is 20 files, with no email and no watermark on your JPGs. Files can be up to 25 MB, and Standard plans and above also get priority processing.
What happens to my files?
They go over a secure HTTPS connection and are deleted from our servers one hour after processing. We don't keep them, look at them or reuse them.
Can I use it on my phone?
Of course. It works in any modern browser on Android, iOS, Windows, macOS and Linux, so there's no app to install.

Convert to JPGCommon questions about converting PNG files
Things people often ask before converting.
How do I convert PNG to JPG?
It's the Convert to JPG button once the files are in. Before pressing it, we'd check two settings: the colour for any see-through parts, and the quality. The JPGs are ready a few seconds later.
Will the JPG lose quality?
A little detail goes, but at quality 85 to 92 we couldn't see it at normal size. Logos and sharp text are the exception and look better left as PNG.
What happens to the transparent background?
It gets filled in, because JPG has no way of storing see-through. In our test the empty half came out white on the default setting, and beige when we typed #F5E6CC.
Why is my JPG so much smaller than the PNG?
Mostly because PNG doesn't throw anything away. Our example screenshot was 596 KB as a PNG and 162 KB as a JPG.
Can I convert multiple PNG files at once?
Yes. Several files or a whole folder can go in together. One file is 1 credit, and the free daily allowance is 20.
Can I do this on my phone?
Yes. We built it to run in a phone browser. Screenshots can be picked straight from the gallery, and the JPGs download like any other file, with no app involved.
