Frequently asked questions
Which formats can I convert?
The ones your browser can open: JPG, PNG, WebP, GIF, BMP and, in recent browsers, AVIF. SVG vector images cannot be converted. iPhone HEIC photos only open in Safari. For an animated GIF, the first frame is converted.
Which format should I choose?
JPG for photos: it is small and opens anywhere. PNG for screenshots, logos and images with transparency: it loses no quality, but is larger. WebP is smaller than both and keeps transparency.
What happens to transparency when converting to JPG?
JPG does not support transparency, so transparent areas become white. PNG and WebP keep it.
Is any quality lost?
Not to PNG: it stores the image losslessly. To JPG and WebP it is saved at a high quality of 92%, and the difference cannot be seen. Converting a JPG to PNG does not bring back quality it has already lost.
Are my images uploaded to a server?
No. They are converted in your browser: this tool does not send or store them. The converted image does not keep the original’s metadata, such as the location.
JPG, PNG or WebP: which to choose
All three formats store the same thing, an image, but by different rules. JPG compresses by discarding detail, which works very well for photographs. PNG keeps every pixel exact and supports transparency, at the cost of larger files. WebP is more recent and combines both with smaller files.
| Format | Compression | Transparency | Best for |
|---|---|---|---|
| JPG | Lossy | No | Photographs: small files that open in any program |
| PNG | Lossless | Yes | Screenshots, logos, graphics with text |
| WebP | Lossy or lossless | Yes | Images for web pages: the smallest at the same quality |
The most common conversions
From PNG to JPG, to cut the size of a photo or a screenshot that does not need transparency: the file usually ends up several times smaller. Transparent areas become white.
From WebP to JPG or PNG, when you download an image from a website and the program you want to use it in will not open it. From JPG to PNG, when a platform requires that format or you are going to keep editing the image and do not want it to lose more quality every time you save.
From JPG or PNG to WebP, to publish images on a web page at the smallest possible size. Every current browser displays it.
What a conversion cannot do
Converting does not improve an image. Turning a JPG into a PNG does not bring back the detail the JPG already discarded: it only stops it losing more. Nor does transparency appear where there was none: a JPG with a white background still has a white background as a PNG.
The conversion is done in your browser, without uploading the images to any server, and the new file does not keep the original’s metadata, such as the date or the location of the photo.
