JPG, JPEG and WebP
The conversion runs in your browser, your images are not uploaded.
Save JPG photos as lossless PNG, one by one or many at once. Phone photos are rotated the right way up, WebP works too. Free, no sign-up and no upload.
Drag your JPG files into the field or click “Choose images”. Several images at once are possible, WebP works too.
Every image is saved as lossless PNG right away. The list shows a preview, image size and file size before and after.
Download each image on its own or all together via “All as ZIP”.
Some programs, templates and upload fields demand PNG. Also, a JPG loses a bit of quality every time it is saved again. If you edit an image several times, for collages or presentations, you are better off continuing with a PNG copy.
The PNG file holds every pixel exactly as it comes out of the JPG. Nothing more is lost, but nothing comes back either. Traces of JPG compression stay visible, the conversion does not sharpen or denoise anything.
Photos have countless fine colour gradations that PNG has to store without loss. The file often ends up several times the size of the JPG. That is impractical for email or web pages and just right for further editing.
Want a PNG to get smaller, or a portal only takes JPG? There is PNG to JPG for that. You can combine several photos into one document with JPG to PDF.
No. PNG is lossless, so the conversion adds no further loss. But whatever JPG compression has already changed, such as slight blockiness or smears along edges, stays. The PNG file shows exactly what is in the JPG.
PNG compresses without loss and therefore saves far less space on photos than JPG. A photo as PNG is often several times the size of the JPG. That is normal and not an error. If you only need a small file, stay with the JPG.
No. A JPG has no transparency, so the PNG has no see-through areas either. The background stays as it is in the photo. Cutting it out is a separate step.
When a program, a form or a print shop explicitly asks for PNG. And when you want to edit and save an image several times: every new save as JPG costs a little quality again, as PNG it does not.
Yes. Many phones store the rotation only as a note in the metadata. The tool applies that note first, so the PNG looks the way you see the photo in your gallery. The other metadata such as capture date, camera or location is not carried over.
No. The conversion runs entirely in your browser, the images never leave your device. You can convert as many images as you like, WebP too, as long as your browser can read it.
