Compresser is the fastest, most private way to shrink files on your phone — photos, videos, PDFs and audio, all processed 100% on-device. Nothing ever leaves your phone.
What it does

JPEG, PNG, HEIC and WebP — adjust quality, resize and convert between formats, one photo or a whole batch.
Videos
MP4, MOV and AVI — dramatically reduce file size while preserving watchable quality.
PDFs
Optimize document structure and strip metadata to make PDFs email-friendly.
Audio
MP3, WAV, AAC and FLAC — smaller files that still sound right.
Private by design
No cloud uploads, no accounts, no sign-up, no tracking. Everything runs locally, results in seconds.
