Bulk Image Compressor MB to KB

Running out of phone storage? Camera photos eat megabytes, and uploads fail the moment a file passes the size limit.

Bulk Image Compressor shrinks photos from MB to KB in seconds, right on your device. Pick an exact target size — 100 KB, 500 KB, 1 MB — and the app tunes quality automatically to land at or below it. It handles single photos and whole batches alike, so holiday albums and work documents shrink just as fast. No accounts, no uploads, no waiting on servers.

Key Features:

- Batch Resize and bulk compression: shrink up to 10 photos at once with a single tap. Every file is processed individually with its own quality tuning, then you can save or share all the results together.

- Precision KB targeting: type the exact size you need, from 20 KB up to 5 MB, and the app estimates the quality that lands at or below it. Made for upload forms, email attachments, and messaging apps with strict size limits.

- 100% Offline Compressor: every byte is processed on your phone, so shrinking works with zero connection and your pictures never leave the device. No accounts, no servers, no waiting.

- Quality-first output: smart quality estimation keeps photos sharp while cutting size. JPG, PNG, and WebP are supported, with before-and-after file sizes shown side by side so you always see what changed.

- Built-in Photo Resizer: set width and height in pixels with the aspect ratio locked, or crop, rotate, and flip before you export. Your originals stay untouched, and every export is saved as a new file.
