BATCH COMPRESSION

Compress multiple photos or videos in one workflow instead of processing each file separately.

COMPARE AND SHARE

See the original and output file sizes before saving. Share compressed files directly with other apps using Android's share features.

LOCAL-FIRST PROCESSING

Core file processing is designed to run locally on your device, without requiring cloud upload for the main compression workflow.

SizeDown is built for everyday tasks such as reducing a photo before uploading it, shrinking a video for messaging, or preparing a PDF for a file-size limit.
