How do I change a PNG to a JPG?

Drop the file onto the tool at the top of this page. The JPG appears within a second, ready for the Download button. You can also click Choose files or press ⌘V / Ctrl+V to paste from the clipboard. No software to install, no account to create.

Can I change multiple PNG files to JPG at the same time?

Yes — add up to 50 files in one batch. Each file is changed to JPG the moment it enters the list, and Download all saves every result one after another. Adjusting the quality slider re-processes every file at the new setting.

Does changing a PNG to JPG reduce quality?

JPG uses lossy compression, so some data is technically lost, but at the default quality of 90 the difference is invisible on photos and screenshots. Push the slider to 100 for the closest match, or lower it when file size matters more than fine detail.

Why does the transparent area in my PNG turn a solid colour?

JPG has no transparency support, so every see-through pixel must become a solid colour. Most tools default to black, which puts dark boxes behind logos and icons. This tool paints white by default and lets you change that to black, grey or any custom colour you choose.

Is it safe to change PNG to JPG online?

With this tool, yes — nothing is uploaded. Your browser decodes the PNG and re-encodes it as JPG on your device. No server ever sees your files. Closing the tab releases everything from memory.

Is there a file size limit?

No fixed cap. The conversion runs locally, so the only limit is what your browser can hold in memory. If a file is too large for full-size encoding, the tool steps down to 32, 16.7, 8 or 4 megapixels and shows the size it used.

Can I change PNG to JPG on my phone?

Yes. The tool runs in any modern browser — Safari on iPhone, Chrome on Android, or any desktop browser. No app needed, same 50-file batch limit everywhere.

What is the difference between changing and converting?

Nothing — changing a PNG to JPG and converting a PNG to JPG mean the same thing. The browser decodes your PNG pixels, fills transparent areas with a background colour, and re-encodes the result as a JPG at the quality level you set.

JPG has no transparency, so see-through pixels get this colour.

How to change PNG to JPG

Three steps, a few seconds per file — no software, no account.

Add the PNG files you want to change
Drag one or more PNGs onto the drop zone, click Choose files, or paste a screenshot with ⌘V / Ctrl+V. You can add up to 50 files in one go.
Set quality and background colour
Move the quality slider between 50 and 100 (default 90). Choose white, black, grey or a custom colour for transparent areas — JPG cannot store transparency, so a fill colour replaces it.
Save your new JPG files
Click Download for a single file, Download all for the full batch, or Copy to put the image on your clipboard. Every file keeps its original name with a .jpg extension.

Why change from PNG to JPG?

PNG stores every pixel losslessly and supports full transparency, which is why screenshots and graphics look crisp but produce large files. JPG uses lossy compression tuned for photographs and visual content: it drops detail the eye barely notices and produces files that are a fraction of the size.

The most common reason to change from PNG to JPG is file size. Upload forms, email attachments, website images and social-media posts all have size limits or load faster with smaller files. A 5 MB PNG screenshot often becomes a 200–400 KB JPG at quality 90 with no visible difference.

When you change the format here, the browser decodes the PNG into raw pixels, paints the background colour you chose behind any transparent areas (JPG has no alpha channel), and re-encodes at the quality level you set. The result is a new file — the original PNG is never modified.

Your files stay on your device

The entire process runs inside your browser tab. No file, filename or pixel is sent to any server — which is why the first result appears instantly instead of after an upload. Once the page has loaded you can disconnect from the internet and keep going.

Closing the tab releases every copy held in memory. There is nothing to delete and no account to deactivate.
