You can change an image format on Android without downloading any app — just open Chrome, go to the free WildandFree Image Converter, pick your image, select the output format, and download. The whole process takes under 15 seconds and works on any Android phone.
Most image converter apps in the Play Store collect your photos, display ads, and require permissions they don't need. The browser method skips all of that — your images never leave your device, and there's no account to create.
How to Change Image Format on Android in Chrome
Follow these steps on any Android phone or tablet:
- Open Chrome on your Android phone (or any browser you prefer)
- Go to wildandfreetools.com/image-tools/image-converter/
- Tap "click to select" in the drop zone — your file picker will open
- Browse to your image in Photos, Downloads, or Files
- Choose your output format: JPG, PNG, or WebP
- Adjust quality if needed, then tap "Convert & Download"
The converted file downloads to your phone's Downloads folder. You can access it in the Files app, Google Files, or whatever file manager you use.
On Samsung phones: Samsung's built-in file picker may not show Photos initially — tap "Browse" or switch to "Downloads" to find your photos folder.
What Formats Can You Convert on Android?
The browser converter supports JPG, PNG, and WebP in any combination:
- JPG to PNG — useful when you need transparency or a lossless copy of a photo
- PNG to JPG — reduces file size for photos significantly (PNG photos are 3–5x larger than JPG)
- JPG to WebP — creates a smaller file for sharing online or uploading to websites
- PNG to WebP — modern format with transparency support and better compression than PNG
- WebP to JPG or PNG — useful when an app won't accept WebP files
Need to convert HEIC photos from an iPhone? Android doesn't save HEIC natively, but if you received HEIC files, there are dedicated HEIC converters built for that format.

Most image converter apps in the Play Store have problems that the browser approach avoids:
- Unnecessary permissions: Many request access to your entire photo library, contacts, or location — permissions a converter has no legitimate use for.
- Ads and paywalls: Free tier converters often watermark output or limit how many conversions you can do per day.
- Cloud upload: Some apps upload your image to their servers before converting — a privacy concern for personal or work photos.
- Storage: Every installed app takes up space. Browser tools require zero storage.
The browser converter avoids every one of these issues. The tradeoff is that it requires an internet connection to load the page (though once loaded, it works offline).
Does This Work on Samsung Galaxy, Pixel, and Other Android Phones?
Yes. The converter runs in Chrome or any modern Android browser. It has been tested on:
- Samsung Galaxy S and A series (Chrome and Samsung Internet)
- Google Pixel phones (Chrome)
- OnePlus and Motorola devices
- Android tablets (Chrome and Firefox)
Any Android device running Android 8 or later with a modern browser will work. The conversion processes using your device's browser engine — no server involved.
For compressing images after conversion (reducing file size further), see the free image compressor which also runs in Chrome on Android.
