Get pictures into the format a website, an app or a print shop asks for. Drop them below, compare the sizes, and convert them all on your device.
1
Drag JPG, PNG, WebP or GIF files onto the box above, or click Choose Files. Mixed formats are fine, and you can add many at once.
2
The assistant opens with your images and shows the formats they can become, each with the size it would give your files, and warns you when one would make them bigger. Tap the one you want.

Every image comes back in its new format with a download button. The files you dropped stay exactly as they were.
JPG is the safe choice for photos: nearly every device, app and website accepts it, and it keeps files small. PNG stores every pixel exactly and supports transparency, which suits logos, icons and screenshots of text. WebP usually makes the smallest file of the three for the same look, and current browsers and most modern apps open it.
Seeing the sizes first takes the guesswork out. A photo turned into a PNG often grows to several times its size; that is normal for the format but rarely what you want, so the options point it out before anything is converted. For JPG and WebP you can also ask for a quality from 1 to 100, or for a smaller longest side, in the same request.
GIFs are read as a still picture from their first frame, and iPhone HEIC photos open only in Safari, which decodes them itself. JPG cannot store transparency, so see-through areas turn white; PNG and WebP keep them. Each picture is converted in your browser, and the new file leaves out hidden details such as the place it was taken.
JPG for photos you want to share or upload, PNG for graphics with sharp edges or a transparent background, and WebP for the lightest files on a website. When in doubt, compare the sizes shown for your own images.
Only in Safari, which opens HEIC files itself. In other browsers, export the photo as JPG from your phone first, or set the iPhone camera to save its photos as JPG.
No. The converter writes JPG, PNG and WebP only. A GIF you drop is read as a still image, and the result is saved in one of those three formats.
No. It works in a modern web browser on a computer or a phone, with no account to create, nothing to install and no watermark on the result.
No. Every result is saved as a new file, and the file you dropped stays exactly as it was.
