How to use it
- PNG is already selected — tap “Select Images” and choose one or more JPG files.
- Each image is converted in a second, right on your device.
- Tap “Download” for one file, or “Download all as ZIP” for many.
When should you convert JPG to PNG?
Convert to PNG when an app or website specifically asks for it, or before editing an image several times — PNG doesn't lose quality each time it is saved. Note that converting won't make a JPG sharper, and PNG files are larger, so keep JPG for uploading photos to forms.
JPG vs PNG vs WebP — which should you use?
| Format | Best for | Transparency | File size |
|---|---|---|---|
| JPG | Photos, exam & job forms | No | Small |
| PNG | Logos, screenshots, text, signatures with transparency | Yes | Large |
| WebP | Websites and apps | Yes | Smallest |
Most government and bank portals accept only JPG/JPEG for photos and signatures. Need it under a size limit too? Use Compress Image to KB after converting.
