Pixformat is a free image converter that runs in your browser. Add JPG, PNG, WebP, GIF or BMP files, pick JPG or PNG (plus WebP and AVIF if your browser can create them), and download the results one by one or as a ZIP. Your images are not uploaded to a server.
Pixformat converts photos, screenshots, logos and other pictures on your device, so there is no upload to wait for.
Pick what you need and see the format to use. The converter above lets you set it before you click Convert.
| 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. 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.
PNG and WebP keep transparent areas. JPG can't store transparency, so Pixformat fills transparent areas with white.
Pixformat converts only the first frame, so the result is a still image.
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. Very large images can fail on devices with limited memory.
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. If you need one of those, use the original file or another tool.
Yes. There is no sign-up, Pixformat adds no watermark to your images, and the page loads no ad scripts.
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.
From JPG, PNG, WebP, GIF and BMP. To JPG and PNG, plus WebP and AVIF in browsers that can create them.
It depends on the output. PNG is lossless, so it adds no compression loss. JPG, WebP and AVIF are lossy: Pixformat saves them at a fixed quality of about 85%, 82% and 65%, and a lossy file can't get back detail it has already lost. Keep your originals.
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.
Only the first frame is converted, so you get a still image.
JPG doesn't support transparency, so Pixformat fills transparent areas with white when you choose JPG. Choose PNG or WebP to keep transparency.
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.
