Compresser is a fast, private way to shrink files on your iPhone & iPad. Reclaim storage, share smaller files – all 100% on your device. Your files are processed on your device.
Why Compresser?
Your privacy matters. Compresser processes everything locally. This means:
• No Cloud Uploads: Files stay on device.
• No Accounts, No Sign-Up.
• No account and no cloud upload — files are processed on your device.
• Fast Results: Results in seconds.
• Quality Preservation: Reduce size, maintain quality.
What You Can Compress:
• Photos: JPEG, PNG, HEIC, WebP – adjust quality, resize, convert.
• Videos: MP4, MOV, AVI – dramatically reduce size.
• PDFs: Optimize structure, strip metadata.
• Audio Files: MP3, WAV, AAC, FLAC – smaller files, great sound.

Privacy First:
Compresser is built on privacy. Your files are processed locally, never uploaded. We do not upload your files for compression. The free version uses Unity Ads, and the app uses crash and performance diagnostics as described in the privacy policy. Ad personalization follows your consent choices.
