Convert images from JPG, PNG, WebP, BMP or GIF
One page for the common format pairs. Drop in a WebP from a website, a BMP from an old program or a GIF from a chat — and get back something that opens anywhere.
This changes the format — JPG, PNG, WebP, GIF and BMP. The pixel dimensions and the picture itself stay as they are. To change the size in kilobytes instead, use the Image Compressor; to change the width and height, use the Image Resizer.
How it works
Add your image
JPG, PNG, WebP, GIF and BMP all drop straight in.
Choose what you need
JPG for photos and forms, PNG for screenshots and transparency, WebP for the web.
Convert
Press the button and the file is rewritten in the browser.
One image at a time, as many as you like. Nothing queues and there's no daily cap.
The picture never leaves your device
Compressing or converting a photo usually means sending it to somebody else's computer and getting a new one back. Here the work happens in the page you are already looking at: your browser opens the file, the tool rewrites it, and the browser hands you the result.
- Opened from your disk by your browser — not sent anywhere first.
- Held in the tab while the tool works, then dropped.
- Saved to your device by your browser, not by a link to a server.
- Closing the tab clears the working copy completely.
- No account, so nothing is ever attached to an identity.
- No tracking of what you worked on or what was inside the file.
There is no queue and no waiting room. The picture is worked on in front of you and released the moment the tab closes. You can read more about how the conversion runs on your own device, or check our guide to verifying it in DevTools.
What people use it for
Opening a WebP you can't view
Older apps, email clients and content systems still refuse the newer format; JPG and PNG open everywhere.
Keeping a screenshot sharp
PNG keeps crisp edges on text and interface; JPG smears them.
Making images smaller for a website
WebP is typically 25–35% smaller than JPG at the same visual quality.
Getting an image past a submission form
Most portals accept only JPG or PNG, often under a fixed file size.

When something goes wrong
Damaged files, and formats outside the list above, stop with a plain message rather than a spinner that never finishes. If a picture opens in your gallery it will normally open here.
The format is not supported. Convert it to PNG or JPG first, or try one of the other image tools.
Why not an upload site
An upload-based tool is a form that posts your picture to someone else's machine. Take that step out and a lot of small annoyances disappear with it.

Questions
Which formats can I convert between?
JPG, PNG, WebP, GIF and BMP. Pick any one as the source and any other as the output.
What's the difference between WebP and JPG?
Both are for photos. WebP gives you the same picture in a noticeably smaller file and, unlike JPG, it can do transparency.
Which format gives the smallest file?
WebP, usually — around 25–35% smaller than JPG at the same visual quality. PNG is the opposite: it keeps every pixel, so it is often the largest of the three.
Will converting to JPG lose transparency?
Yes. JPG has no transparency, so any see-through areas are filled in, usually with white. Use PNG or WebP if you need to keep them.
Does converting reduce quality?
Going into JPG does, slightly. Going into PNG doesn't — it keeps every pixel. Repeatedly converting the same image between lossy formats will degrade it, so always work from the original.
Can I convert more than one image at a time?
One at a time. The tool takes a single image and hands back a single file. There's no queue and no daily cap, so you can run through as many as you need, one after another.
