Image Compressor for Android — Free, Fast & Private

Most image compressor apps on the Google Play Store want access to your entire photo gallery, show ads on every screen, and push you toward a paid subscription. Some upload your photos to remote servers for processing. You should not have to deal with any of that just to make a photo smaller.

MiniPx works in any Android browser — Chrome, Firefox, Samsung Internet, Opera, Brave — without installing anything. Open the URL, pick your photos, compress, download. Your images never leave your phone. No permissions requested, no ads, no account needed.

Why use a browser tool instead of an app?

Android compressor apps like Photo Compress 2.0, Image Size, and Lit Photo ask for storage permissions that give them access to your entire gallery. Even if the app itself is trustworthy, that permission surface is unnecessarily broad. A browser-based tool like MiniPx only accesses the specific files you select — nothing else on your device.

There is also no storage overhead. Apps take up space, need updates, and accumulate cache. MiniPx is just a webpage. Close the tab and it is gone. If you want the app-like experience, you can install MiniPx as a PWA — add it to your home screen from Chrome and it launches like a native app, but with zero storage footprint.

What can you do on Android?

Everything the desktop version offers. Compress JPEG, PNG, WebP, and AVIF images. Convert between formats. Resize to specific dimensions. Compress to a target file size (100KB, 50KB, 20KB — useful for government form uploads). Batch process multiple images at once. Strip EXIF metadata for privacy.

Works offline too

Once MiniPx loads in your browser, it works without an internet connection. You can compress images on a flight, on the metro, wherever. The entire compression engine runs locally in your browser.

Compare with popular Android apps

Photo Compress 2.0 is ad-supported and limited to JPEG/PNG. Image Size requires a subscription for batch processing. Lit Photo uploads images to servers. MiniPx is free, unlimited, private, supports 7+ formats, and runs in any browser without installation. For most people, that is the better deal.
