PNG to JPG Converter: Free, No Sign-up, Files Never Leave Your Device
Convert PNG to JPG for free, right in your browser. There is no sign-up or login, no watermark, and no upload: your files never leave your device. It is the quick way to turn screenshots and graphics into smaller files that every site, form and app accepts.
PNG stores every pixel exactly, which makes files large. JPG uses lossy compression, so a photo or screenshot usually shrinks a lot, at the cost of some fine detail. The conversion runs natively in your browser with no engine to download.

About the formats
PNG vs JPG
PNG is lossless and keeps a full alpha channel, so it suits screenshots, logos and graphics with sharp edges and flat colour. JPG is lossy and has no transparency, which suits photographs.
Going from PNG to JPG is a one-way trade: the detail JPG discards cannot be recovered by converting back.
Privacy: how it works
- Your PNG files stay on your device. The page reads each file with the browser's file API, converts it with code running in the tab, and hands the result back as a download. No upload happens, so there is no copy of your file on our servers to protect, delete or leak.
- There is nothing to sign up for and no login. The converter does not ask for an email address, and it does not need to know who you are to do its job.
- You can check the claim yourself: open your browser developer tools, watch the Network tab while a file converts, and you will see no request that carries your file.
- The JPG is drawn from your PNG on a canvas inside the tab, so the only copy of the result is the one you download.
Tips
- Expect a white background where your PNG was transparent. If you need another colour, place the image on it first.
- Text and thin lines can show faint fringes in JPG. Keep the PNG for sharp interface screenshots.
- Convert photos saved as PNG: they gain the most from JPG.
- Keep your original PNG files, since JPG cannot restore what it drops.
- Do not convert a JPG again and again, because each lossy save adds artefacts.
- Use JPG when a form or old app rejects PNG.
Frequently asked questions
Is it really free?
Yes. There is no price, no trial, no credit card and no watermark added to your results. Ulkaa Tool does the conversion with your own device, so there is no server bill to pass on to you.
Are my files uploaded?
No. Your PNG files are read and converted inside your browser and are never sent to Ulkaa or to anyone else. The result is created on your device and you save it from there.
Do I need an account?
No. There is no sign-up and no login. Open the page, add your files and convert. An Ulkaa account is not needed for anything on this tool.
Is there a file size limit?
No limit is set by us. The real limit is your device: the conversion uses your own memory and processor, so very large files can be slow, and a very big batch may need to be split into smaller runs.
