How to convert PNG to JPG
Add your PNG files
Drag them onto the box, choose them with the button, or paste a screenshot straight from the clipboard. Add as many as you like.
Choose quality and background
JPG quality 90 suits photos; for screenshots with small text, 95 keeps the letters crisp. Transparent areas get the colour you pick – white by default.
Download
Save each JPG on its own, or all of them at once as a ZIP file.
Screenshots often show more than you think
A screenshot can contain an open chat, an email address, a bank balance or a customer's name. Uploading it to an online converter hands all of that to someone else's server. KeepPixels converts it inside your browser instead – nothing is sent anywhere, and once the page has loaded it even works offline.
PNG and JPG in a nutshell
PNG (Portable Network Graphics) stores every pixel exactly, without loss, and supports transparency. That makes it ideal for screenshots, logos, diagrams and anything you plan to edit again. The price is size: a photo saved as PNG is often five to ten times larger than the same photo as JPG.
PNG vs JPG at a glance
| PNG | JPG | |
|---|---|---|
| Compression | Lossless | Lossy, adjustable |
| Transparency | Yes | No |
| Size of a photo | Large | Small |
| Best for | Screenshots, logos, graphics, editing | Photos, uploads, email |
When converting to JPG makes sense
- An upload form or portal only accepts JPG, or has a size limit. For a fixed limit, use compress to an exact size.
- You want to send many screenshots or photos by email or chat.
- A phone or an app saved photos as PNG and they take up too much space.
When to keep PNG
- Logos, icons and images that need a transparent background.
- Graphics with large flat areas or thin lines, where JPG can leave a faint blur around the edges.
- Files you will keep editing: every JPG save loses a little more detail.
If a PNG is simply too big, compress it as PNG instead: reducing the colours often makes screenshots much smaller while they look almost the same, and transparency is kept.

Frequently asked questions
Can I convert PNG to JPG without losing quality?
Not entirely, because JPG always compresses with some loss. For photos saved as PNG you won't see a difference at quality 90. Screenshots with sharp text and flat colours are more demanding, so use 95 – or keep them as PNG and shrink them with the image compressor, which makes PNGs smaller without converting them.
What happens to transparent areas?
JPG can't store transparency, so transparent pixels are filled with a solid colour. White is the default. You can switch to black or pick any other colour, for example to match the page where the image will appear.
How much smaller will the file be?
That depends on the picture. A photo saved as PNG often shrinks to a fifth of its size or less. A screenshot of a mostly white window shrinks less, and a simple graphic with only a few colours can even stay smaller as PNG.
Are my images uploaded?
No. Your images are read and converted by your own browser and never sent to a server. You can check this in your browser's developer tools (Network tab) – no image data goes out.
What about animated PNGs (APNG)?
The JPG contains the first frame. JPG has no way to store animation.
Does it work on a phone?
Yes, in Safari, Chrome and other current browsers. Choose the screenshots from your photo library and save the JPGs back to it or to your files.
Is it really free, with no limits?
Yes. There's no sign-up, no daily cap and no maximum number of files. The only limit is your device's memory.
