Compressly vs ShelfCheck Pro

That 4K video you just shot is eating your storage, and it's too big to text, post, or back up. Compressly shrinks it in seconds — right on your iPhone — so you keep the moment, lose the gigabytes, and never wait through a spinning wheel or a crash again. THE FASTEST COMPRESSOR ON IPHONE Compressly uses your iPhone's built-in hardware video encoder instead of slow software conversion. A clip that takes other apps minutes is done in seconds, and it won't choke or crash on long 4K recordings. Fast and stable, every time. PICK YOUR QUALITY IN ONE TAP Three simple presets cover everything: Low for the smallest possible file, Medium for everyday sharing, and High when you want to keep a video looking great. No confusing bitrate sliders or codec menus — just choose and go. SMART AI RECOMMENDATIONS Tell Compressly what the video is for and it picks the right settings for you — trimmed down for WhatsApp and iMessage, sized right for Instagram and social, or kept high-quality for archiving. The perfect balance of size and quality without the guesswork. COMPRESS IN BATCHES Select up to 20 videos and compress them all in one run. Compressly works through them one by one, shows live progress, and gives you a single summary of everything you saved — perfect for clearing out a full camera roll. SEE EXACTLY HOW MUCH YOU SAVE Every result shows your Before and After size and the percentage you reclaimed, front and center. A running lifetime total tracks every gigabyte you've freed, so clearing space finally feels rewarding instead of tedious. 100% ON-DEVICE, ALWAYS PRIVATE All compression happens on your iPhone using Apple's own frameworks. Your videos never leave your device, there's no account to create, no ads, and no tracking. Compressed files are saved into a dedicated Compressly album so your originals stay untouched and nothing gets mixed up. WHY COMPRESSLY • Hardware-accelerated compression — fast and crash-free • Low / Medium / High presets, no technical settings to learn • Smart AI recommendations for WhatsApp, social, and archiving • Batch compress up to 20 videos at once • Before/After savings and a lifetime space-saved tracker • Saves to a separate Compressly album — originals stay safe • 100% on-device — nothing is uploaded • No account, no ads, no tracking For everyone whose iPhone storage is always full — shrink your biggest videos in seconds, share them anywhere, and stop paying for storage you didn't need.
