A PNG screenshot or photo can be five or ten times larger than it needs to be. Converting it to JPG squeezes that same picture down to a fraction of the size, which makes it easy to slip under an email attachment limit, upload faster on a slow connection, or store a whole folder of images without eating your disk. The PNG to JPG Converter does exactly that, for free, with no account and no watermark.
The important part: the conversion runs entirely in your browser — your files never leave your device. There is no upload to a cloud server and nothing to delete afterward, because your image is decoded and re-saved right on your own machine using the browser canvas. That means it also works offline once the page has loaded, and it is safe for private screenshots you would rather not hand to a random website.
How to convert PNG to JPG
The whole process takes about ten seconds and there is nothing to install. Here is the full flow:
- Open the tool. Go to the PNG to JPG Converter. It loads as a normal web page — no download, no plugin.
- Add your PNG. Drag the file onto the drop zone, or tap to pick it from your files or camera roll. You can add several PNGs at once.
- Let it convert in your browser. The tool draws your PNG onto a canvas and re-encodes it as a JPG right there on your device. Nothing is uploaded, so even a big screenshot finishes almost instantly.
- Download the JPG. Save the smaller file back to your device. Do a quick before-and-after size check — a photo-heavy PNG often drops by 70% or more.
Because the work happens locally, you can start it, flip your phone to airplane mode, and it will still finish. That is the opposite of most "online converters," which need a live connection because they ship your file off to a server first.

Convert PNG to JPG →PNG vs JPG: why the file size gap is so big
PNG and JPG are both everywhere, but they are built for different jobs. PNG is lossless — it keeps every single pixel exactly as it was, which is fantastic for sharp text, logos and transparent graphics, and terrible for keeping file size down on a photograph. JPG is lossy — it throws away visual detail your eye barely registers, and that compression is tuned specifically for photographs, so a photo saved as JPG can be a tiny fraction of the same photo saved as PNG.
| Trait | PNG | JPG |
|---|---|---|
| File size for photos | Large — often several MB | Small — frequently 5–10× smaller |
| Transparency | Yes — full alpha channel | No — flattens to a solid background |
| Compression type | Lossless (keeps every pixel) | Lossy (drops unnoticed detail) |
| Best for | Logos, icons, text, screenshots, cutouts | Photos, email attachments, fast uploads |
The one real tradeoff to know about: JPG cannot store transparency. If your PNG has a see-through background — a logo or a product cutout — converting to JPG will flatten those transparent areas onto a solid color, usually white. For a normal photo or a full-frame screenshot that does not matter at all. But if you specifically need to keep that transparent background, go the other direction and use the JPG to PNG route, or keep the file as a PNG. And if you started from a modern web image, our WebP to JPG guide covers the same shrink-it-down move for .webp files.
There is also a light quality tradeoff. JPG is lossy, so on flat graphics with hard edges you might spot faint fuzz around text. On photographs and most screenshots at a high quality setting, it is invisible. The rule of thumb: photos and photo-like images convert beautifully to JPG; crisp logos and line art are happier staying PNG.
Works on Windows, Mac, iPhone, and Android
The PNG to JPG Converter is just a web page, so it runs anywhere a modern browser does. That means Chrome, Safari, Edge and Firefox on Windows, Mac, iPhone and Android — same tool, same steps, nothing to install from an app store.
- On a laptop or desktop: drag the PNG straight from your desktop or a folder onto the drop zone.
- On a phone or tablet: tap the drop zone, pick a screenshot from your photos, and download the JPG right back to your camera roll or Files app.
There is no separate "mobile version" that is missing features. Because the conversion is done by your browser's own canvas engine, a mid-range phone handles it just as well as a workstation, and a batch of images is limited only by your device's memory — not by an upload cap someone set on a server.
Your files stay private — here's why that matters
Most free "online" converters follow the same pattern: you pick a file, it gets uploaded to their server, converted there, and handed back as a download. Even when a site promises to delete your files later, you have already sent a copy off your device to a machine you do not control. For a meme, who cares. For a screenshot of a bank statement, a medical form, a passport photo or a tax document, that is a real problem.
EZ PDF Editor works the other way around. The canvas that redraws and re-encodes your image lives inside your browser, so the conversion runs entirely in your browser — your files never leave your device. Nothing is transmitted, nothing is stored on our end, and there is nothing to "delete from the server" because it was never there. A few practical consequences:
- It works on airplane mode. Once the page has loaded, you can go fully offline and still convert.
- It is safe for sensitive images — IDs, medical paperwork, financial screenshots — because they stay on your machine.
- There is no account, no email and no watermark, so nothing about you gets collected in exchange for a conversion.
The same local approach powers our sibling tools. If you eventually need those images inside a document, the PNG to PDF tool assembles them into a single PDF the same private way. And when you need the transparency back, converting JPG to PNG runs locally too.
The short version
PNG is the format you want for pixel-perfect logos, text and transparent cutouts, but it makes photos and screenshots needlessly heavy. When file size matters — an email limit, a slow upload, a crowded drive — convert those images to JPG and watch them shrink dramatically, keeping in mind that any transparent background will fill in with white. Do it in a few seconds, for free, with everything handled right on your device. Open the PNG to JPG Converter and give it a big screenshot to see the difference.
