About this app

Shrink large photos before you send them, resize them to the exact dimensions you need, and convert between JPG, PNG and WebP — all processed on your phone.

COMPRESS
• Three one-tap presets: High Quality, Balanced, Small Size
• Or set the quality yourself, from 1 to 100
• Or name a target file size — 100 KB, 200 KB, 500 KB, 1 MB or your own number — and the app searches for the best quality that fits, shrinking dimensions only if it has to
• Never produces a file larger than the original

RESIZE
• By percentage: 25%, 50%, 75% or any value you type
• By exact pixels, with an aspect-ratio lock so nothing gets stretched
• By longest edge: 1080, 1920, 2560 px — perfect for uploads with a size limit
• Photos already smaller than your target are left untouched

CONVERT
• JPG, PNG and WebP, in any direction
• Transparency handled properly: PNG areas that are see-through become clean white in JPG instead of turning black
• Quality control for the lossy formats

BATCH
• Process many photos in one go, with live progress and a working cancel button
• One unreadable file never stops the rest of the batch

RESULTS YOU CAN CHECK
• Before and after file size, saved percentage, dimensions and output format for every image
• Results go straight to your gallery, ready to share
• History of everything you processed, with open, share and delete

BUILT FOR PRIVACY
• All processing happens on your device. Your photos are never uploaded anywhere.
• Uses the Android Photo Picker, so the app only sees the images you pick — it asks for no storage permission at all
• No account and no sign-in
• Works completely offline

Handles big photos too: 24 megapixel and larger images, correct portrait orientation from EXIF data, and dozens of images in a single batch.

The free version is supported by ads. A one-time purchase to remove them is coming.
