PNG to JPG Converter
Turn heavy PNG images into compact JPG files right in your browser. Transparent areas are flattened onto white, and your photos never leave your device.
Your PNG files are converted in your browser and never uploaded.
Why convert PNG to JPG
PNG is a lossless format, which is wonderful for graphics but wasteful for photographs. Every pixel of detail in a sunset, a portrait or a document scan is stored exactly, so a single high-resolution photo saved as PNG can weigh five or ten megabytes. JPG was designed for exactly this kind of content: it throws away detail the eye barely notices and packs the rest tightly. The result is a file a fraction of the size that still looks great on screen — the format almost every camera, website and messaging app expects.
Switching from PNG to JPG is one of the quickest wins for page speed and upload limits. A blog hero image, a product photo or a scanned form that was a slow-loading PNG becomes a lean JPG that sends in an instant. This converter does the swap locally, so you keep the speed without handing a private photo to a stranger's server.
The transparency trade-off
The one thing JPG cannot do is transparency. PNG can store a see-through background — the checkerboard you see behind a logo in an editor — but JPG fills every pixel with a colour. When this tool converts a transparent PNG, it paints the image onto a white background first, so the transparent areas become solid white rather than turning black or breaking. For a photograph that is exactly what you want. For a logo or sticker that needs to sit on a coloured page, keep it as PNG, or export to WebP, which supports transparency and small files at the same time.
How to convert PNG to JPG
- Click the box above and select one or more PNG images, or drag them in.

- Press Convert to JPG and wait a moment.
- Compare the original and JPG sizes shown for each image.
- Click Download on each result to save it.
Choosing a quality level
For most photos, 80–90% quality is the sweet spot: the file shrinks dramatically while the picture stays crisp. Drop towards 60–70% when you need to meet a tight upload limit and can accept softer fine detail. Avoid pushing the slider very low on images with text or sharp lines, where JPG artefacts show up first. If you have a hard kilobyte target to hit, the image compressor will search for the best quality that fits automatically.

Frequently asked questions
What happens to transparency when I convert PNG to JPG?
JPG has no alpha channel, so any transparent areas of your PNG are flattened onto a solid white background during conversion. If you need to keep transparency, export to PNG or WebP instead of JPG.
Why convert a PNG to JPG at all?
PNG stores photographic detail inefficiently, so a phone snapshot or screenshot saved as PNG can be several megabytes. Re-encoding it as JPG often cuts the size by 70–90% with little visible difference, which is ideal for email, web pages and uploads.
When should I keep the PNG instead?
Keep PNG for logos, icons, line art, screenshots with text and anything that needs crisp edges or a transparent background. JPG compression adds soft halos around hard edges, so these graphics look better and often smaller as PNG.
Does converting PNG to JPG lose quality?
JPG is lossy, so some fine detail is discarded to save space. At 80–90% quality the loss is hard to notice on photographs. The slider above lets you trade file size against sharpness before you download.
Do my PNG files get uploaded?
No. The PNG is decoded, redrawn and re-encoded on your own device using the Canvas API, so the file never reaches a server. There is no upload progress bar because there is no upload.
Does it work on slow or metered connections?
Yes. The conversion reads and writes the image locally, so no data travels over your connection while it runs and a slow or capped link makes no difference. Only the lightweight page loads once, then it is cached.
Can I convert PNG to JPG offline?
Yes, once the page has loaded a first time. This site is installable as a Progressive Web App and keeps the converter cached, so you can drop a PNG and get a JPG back with no internet connection.
Is there a maximum PNG size I can convert?
No fixed maximum is set. The limit is whatever your device can hold in memory, so an ordinary screenshot or photo converts quickly while an enormous PNG may be slow or fail on a low-memory phone.
Can I convert several PNGs to JPG at once?
Yes. Select or drop multiple PNG files and each one is converted in turn, with its own download button. The same quality setting is applied to every image in the batch.
Image Tools converts PNG images entirely within your browser. Files are never uploaded. For format trade-offs in depth, read our guide to PNG, JPG and WebP.
