Convert PNG to JPG Online
Turn heavy PNG files into compact JPGs in your browser. Set a quality level, pick a background color for transparent areas, and batch convert with no upload and no watermark.
How to Convert PNG to JPG in Three Steps
Drop one PNG or a whole folder, set the JPG quality and background color, then download your files individually or together as a ZIP archive.
Step 1
Add Your PNG
Drag and drop one PNG or several files into the converter to begin.
Step 2
Set Quality
Choose a JPG quality level and the background color used where your PNG is transparent.
Step 3
Download JPG
Save each JPG separately, or grab the entire batch in one ZIP.
Why Convert PNG to JPG — Smaller Files Without Installing Any Software
PNG was designed to be lossless. Every pixel is stored exactly as it was written, which is precisely why screenshots, design exports and product renders grow so heavy. JPG takes the opposite approach: it uses lossy discrete cosine transform compression built around how human vision works, discarding detail the eye barely registers. For a photographic image that trade is overwhelmingly worth making, and the file typically shrinks by half or more. PNG offers no quality slider either, only compression levels that trade encoding time for a few percent of size, so there is no way to make a photographic PNG genuinely small while keeping it a PNG.
This converter performs that trade entirely inside your browser. Your PNG is decoded with the browser’s own imaging engine, painted onto a canvas, and re-encoded as a JPG at whatever quality you select between 10 and 100, with 92 as the sensible default. Because JPG has no alpha channel whatsoever, the tool reveals a background color picker the moment you select JPG output. Transparent and semi-transparent pixels are flattened onto that color before encoding, so you decide what sits behind your image rather than accepting a surprise white box.
The reasons people make this conversion are overwhelmingly practical. Web teams convert oversized PNG exports to JPG so pages load faster and Core Web Vitals stop complaining. Anyone who has hit an email attachment limit knows the feeling. Government portals, job application forms and insurance systems frequently whitelist JPG and reject PNG outright. Content management systems often prefer JPG for editorial photography, print shops ask for it, and social platforms recompress your upload anyway, so starting from a well-optimized JPG gives you a more predictable result. Teams working to a page weight budget usually find that moving photography off PNG is the single fastest saving available.
There are times when you should leave the PNG alone. If the image needs transparency, JPG cannot carry it and the conversion is destructive. If the artwork contains text, sharp lines, logos or flat areas of solid color, JPG compression leaves visible ringing artifacts around every hard edge, and the result looks cheap. If you plan to open and re-save the file repeatedly, each JPG save discards a little more data permanently. Keep the original PNG in those cases and convert only the copy you need to ship.
Everything runs locally on your own device, so there is no upload queue, no ten megabyte ceiling imposed by somebody else’s server, and no account standing between you and the download. Load several files at once and collect the results in a single ZIP. Nothing is watermarked, nothing is capped, and no personal information is collected along the way.
Quality Control
Set JPG quality from 10 to 100 and watch the file size drop as you go.
Background Color
Pick any background color to fill transparent areas before the JPG is encoded.
True Batch Mode
Convert dozens of PNGs in one run and download everything as a single ZIP.
Nothing Uploaded
Files are decoded and encoded locally, so they never touch a remote server.
Keep Dimensions
Pixel dimensions stay identical unless you set an optional maximum width.
No Watermark
Output JPGs are clean, with no logo, badge, or branding added.
FAQ
Frequently Asked Questions
PNG uses lossless compression and stores every pixel exactly, which makes files large. JPG uses lossy compression designed for photographs and typically reduces file size by half or more, making images faster to load on the web, easier to email, and acceptable to systems that reject PNG uploads.
JPG has no alpha channel, so transparency cannot be stored. Before encoding, your image is flattened onto a solid background color that you choose with the built-in picker. The default is white, but you can select any color you prefer.
Some loss is unavoidable because JPG compression is lossy. At quality settings between 85 and 95 the difference is imperceptible for most photographic content. Lower settings produce visibly smaller files but introduce blocking and ringing. Always keep your original PNG so you can re-export later if needed.
Not perfectly. Once JPG compression discards data, that data is gone. Converting the JPG back to PNG produces a lossless file, but it is a lossless copy of an already degraded image, so it will simply be larger without being sharper. Treat the conversion as one-way and archive the original.
Avoid JPG when your image needs transparency, when it contains text, logos, line art or flat colors where artifacts show around edges, and when you plan to re-edit and re-save repeatedly. In all three cases PNG is the better choice despite the larger size.
Yes. Drop several PNG files into the converter at once and every one is processed in the same run. You can download each result individually or grab the whole set together as a single ZIP archive, which is handy when preparing a batch of product photos or screenshots.
No. Decoding, canvas painting and JPG encoding all happen inside your browser using the Canvas API. You can verify this yourself: open developer tools, switch to the Network tab, and convert a file. No image data leaves the page, and nothing is stored once you close the tab.
Open this page in any modern mobile or desktop browser – Safari, Chrome, or Edge all work. Tap Select Images, choose your PNG from the photo library or file picker, and download the JPG. No app install, no desktop software, and the files never leave your device.
For photographs, 85 to 92 gives an excellent balance of size and quality, and 92 is the default here. Push toward 95 only when the image will be viewed at full resolution. For flat-color graphics, stay with PNG, since JPG artifacts show most on hard edges.
No. A 1920 by 1080 PNG becomes a 1920 by 1080 JPG with the pixel grid untouched. There is an optional maximum width field if you want to downscale, which helps when you are also trying to hit a strict file size target for an upload form.
