Kilopix: Photo Compressor

Shrink megabytes down to kilobytes, switch any photo to JPG, PNG, WEBP or GIF, and clear out the space your gallery is quietly eating — all in one app, all on your device.

Kilopix has been rebuilt from the ground up: a new Material You interface, a faster batch engine, and fourteen tools that work on a whole selection at once instead of one photo at a time.

COMPRESS PHOTOS
Drag a single slider and watch the size estimate update live before you export. Preview the exact quality you are about to save, side by side with the original. Turn a 6 MB camera shot into a 300 KB upload without the picture falling apart.

CONVERT IMAGE FORMATS
JPG to PNG, PNG to JPG, WEBP, GIF — pick one output format and the entire batch follows. HEIC, BMP and other camera formats open fine and convert straight out.

RESIZE & CROP
Set exact pixel dimensions or scale by percentage, with the aspect ratio locked if you want it. Crop, straighten and rotate before you export.

EVERY TOOL INSIDE
• Compress — megabytes to kilobytes, quality kept
• Convert — the whole batch into one format
• Resize — exact pixels, or scale by percentage
• Crop & rotate — straighten and trim
• Watermark — a text stamp on every photo
• Remove background — cuts out the subject on-device
• Bulk rename — patterns and counters
• Compare — two photos side by side
• Duplicates & large — find what is wasting space
• Auto-clean — shrink new photos automatically
• Metadata — read EXIF, strip GPS before sharing
• Cloud sources — pull from Drive, Dropbox or Photos
• Share sheet — send images straight in from other apps
• Widget & tile — one tap from your home screen

BUILT FOR BATCHES
Select as many photos as you like. Every tool runs across the full selection with one progress screen, and exports land straight in your gallery. No per-photo tapping, no queue limits.

WORKS OFFLINE, KEEPS YOUR PHOTOS YOURS
Compression, conversion, resizing and background removal all happen on your phone. Your images are never uploaded to a server, and there is no account to create. The metadata tool even lets you strip GPS coordinates out of a photo before you send it to anyone.

FREE TO USE
Every tool is free, with no watermarks added to your exports and no cap on how many photos you process. The app is supported by ads.

Requires Android 7.0 or newer.
