Pick the format you want, add the images, and download them converted. It reads JPG, PNG, WebP, GIF, BMP and AVIF, and writes JPG, PNG or WebP. The default is JPG, because that is the format almost every program, phone and upload form accepts.
The usual reason people land here is a picture saved from a website that turns out to be a .webp file, which an older photo editor, a print shop or a council or employer upload form then refuses. Converting it to JPG fixes that in a few seconds. The reverse comes up too: a logo that needs a transparent background has to be PNG, and a site that loads slowly benefits from WebP.
Up to 30 images can go through at once, 100 MB each. A single file downloads with the same name and the new extension, so banner.webp becomes banner.jpg; a batch comes back as one ZIP.
How to convert Image
- Choose the format to convert to. JPG for photos and maximum compatibility, PNG for graphics and transparency, WebP for use on a website.
- Add your images. JPG, PNG, WebP, GIF, BMP or AVIF, up to 30 files and 100 MB each.
- Convert and download. One image saves with its original name and the new extension; several arrive together in a ZIP.
Which format to pick
JPG is for photographs. It uses lossy compression that suits the smooth gradients of skin, sky and landscape, and it opens everywhere, from Windows Photos to a ten-year-old printer kiosk. Its weakness is sharp edges: text and line art pick up faint smudges around them, and it cannot store transparency at all.
PNG is for screenshots, logos, diagrams and anything with text in it. It is lossless, so every pixel stays exactly as it was, and it keeps transparent backgrounds. The trade-off is size. A phone photo saved as PNG can easily be three or four times larger than the same photo as a JPG, with no visible benefit.
WebP is the web format. It keeps transparency like PNG and compresses photos well, typically coming out 25 to 35 percent smaller than a JPG of similar quality, which is why so many sites now serve it. Use it for images going onto your own website; use JPG for anything you are emailing, printing or uploading to someone else’s system, since support outside browsers is still patchy.
What changes in the converted file
JPG has no transparency, so when a PNG or WebP with a see-through background is converted to JPG, the transparent areas are filled with white. Many converters fill them with black, which ruins logos; white is what you want for a document or a product listing. If you need the transparency kept, convert to PNG or WebP instead.
JPG and WebP output is saved at quality 92, high enough that the conversion is not visible at normal viewing size. PNG output is lossless. The pixel dimensions do not change: a 3000 × 2000 image comes out 3000 × 2000. If you also need it smaller, use Resize Image, and if the file size is the problem rather than the format, Compress Image is the better tool.
Camera and location data, including GPS coordinates, is not carried over to the new file, while the orientation is preserved so photos stay the right way up. Images larger than 16 megapixels are scaled down to 16 megapixels during conversion, because that is the most a browser, iPhones especially, can reliably process in one piece.
GIF, AVIF, HEIC and other edge cases
Animated GIFs are converted using their first frame only, so the result is a still image. That is useful for grabbing a thumbnail, but it will not turn an animation into an animated WebP. AVIF, a newer format some sites and phones produce, can be read as long as your browser is reasonably up to date. BMP files, often from old scanners or Windows Paint, convert normally and usually shrink dramatically as JPG or PNG.
HEIC, the format iPhones use for photos, cannot be read by most browsers, so it cannot be converted here. In practice it rarely needs to be: iPhones normally hand over a JPG when you share, email or upload a photo. If you want JPG on the phone itself, the camera format setting called “Most Compatible” saves new photos as JPG from the start.
Saving to WebP needs browser support too. Older versions of Safari can read WebP but cannot write it; if yours cannot, the tool tells you instead of producing a broken file, and choosing JPG or PNG still works. Updating Safari, or using a current Chrome, Edge or Firefox, removes the limitation.
Questions people actually ask
How do I convert a WebP image to JPG?
Leave “Convert to” on JPG, add the WebP file and download the result. It keeps the same name with a .jpg extension and the same pixel dimensions. If the WebP had a transparent background, those areas become white, because JPG cannot store transparency. You can convert up to 30 WebP files in one batch.
Why won't a picture I saved from a website open?
It is very likely a WebP file, even if the name looks ordinary. Browsers display WebP without trouble, but some older photo editors, office software and upload forms do not accept it. Converting it to JPG gives you a file that opens in practically anything and is accepted by nearly every upload form.
Does converting PNG to JPG lose quality?
Slightly, because JPG is lossy, but at quality 92 the difference is not visible on photographs. It is more noticeable on screenshots and text, where JPG leaves faint artefacts around sharp edges, so keep those as PNG. Transparent parts of a PNG turn white in the JPG version.
How do I convert a JPG to PNG with a transparent background?
Converting to PNG keeps transparency that already exists, but a JPG never had any, so its background stays solid after conversion. To actually make the background transparent, use the Remove Background tool on the image instead of a format conversion.
Can I convert iPhone HEIC photos to JPG here?
Not directly, because most browsers cannot open HEIC files. iPhones usually convert photos to JPG automatically when you share or upload them, and setting the camera format to “Most Compatible” makes the phone save new photos as JPG in the first place, which avoids the problem altogether.
