How to use the free image converter
- Add your images. Drag them into the box or choose files. Pixformat accepts JPG, PNG, WebP, GIF and BMP.
- Pick the output format. Choose JPG or PNG. WebP and AVIF also appear if your browser can create them.
- Click Convert, then download each file or all of them as a ZIP.
Pixformat converts photos, screenshots, logos and other pictures in your browser, on your device. Your images are not uploaded to a server.
Which output format should you choose?
| Format | Compression | Keeps transparency | Good for |
|---|
| JPG | Lossy, fixed quality (about 85%) | No: transparent areas become white | Photos, and forms or apps that ask for JPG |
| PNG | Lossless | Yes | Screenshots, logos, graphics and editing |
| WebP | Lossy, fixed quality (about 82%); offered only if your browser can create WebP | Yes | Images for websites, where WebP is supported |
| AVIF | Lossy, fixed quality (about 65%); offered only if your browser can create AVIF | Yes | Images for websites, where AVIF is supported |
A PNG doesn't add compression loss, but it can't bring back detail that a lossy format such as JPG or WebP already removed. Expect PNG files to be larger. Smaller image files can help pages load faster. Google's tests found lossy WebP files 25–34% smaller than comparable JPEGs, and AVIF files can be smaller than JPEG at similar quality, depending on the image. Your results will vary.
What happens to transparency, animation and file size
- Transparency. PNG and WebP keep transparent areas. JPG can't store transparency, so Pixformat fills transparent areas with white.
- Animated GIFs. Pixformat converts only the first frame, so the result is a still image.
- File size. Each converted file shows how much smaller or larger it became. Moving a photo to PNG usually makes the file larger, and moving a PNG photo to JPG or WebP usually makes it smaller.
- Large images. Very large images can fail on devices with limited memory.
What Pixformat can't convert yet
Pixformat doesn't read HEIC, AVIF, TIFF, ICO, PDF or video files, so it skips them when you add them. It also can't resize images or let you choose the compression quality.
Frequently asked questions
Is Pixformat free?
Yes. There is no sign-up, Pixformat adds no watermark to your images, and the page loads no ad scripts.
Are my images uploaded to a server?
No. Pixformat converts your images in your browser, on your device, and never uploads them. The site does load Google Analytics to measure visits, but it doesn't receive your image files.
Which formats can I convert from and to?
From JPG, PNG, WebP, GIF and BMP. To JPG and PNG, plus WebP and AVIF in browsers that can create them.
Can I convert several images at once?
Yes. Add as many files as you like, convert them together and download them one by one or as a ZIP. Very large batches depend on your device's memory.
What happens to animated GIFs?
Only the first frame is converted, so you get a still image.
Why did my transparent PNG get a white background?
JPG doesn't support transparency, so Pixformat fills transparent areas with white when you choose JPG. Choose PNG or WebP to keep transparency.
Is there a file size limit?
Pixformat sets no file size limit, and nothing is uploaded. Very large images can still fail, depending on your browser and the memory of your device. If a file doesn't convert, try a smaller image.
