Sqizzi
Scan your library
File sizes, resolution, duration, frame rate and HDR are indexed with metadata only. Originals are never copied or downloaded just to be measured.

Keep the memories.
Drop the megabytes.
Sqizzi compresses the photos and videos already on your phone — resizing, re-encoding and trimming bitrate until a file is a fraction of its size. At the quality-first settings, the difference is one you'd have to hunt for. No account, no uploads, no tracking, and it works in airplane mode.

How it works
Three steps, zero uploads
Sqizzi behaves like a storage analyzer and a compressor in one. It reads what is on your phone, shows you where the space goes, and writes smaller copies right next to the originals.
Pick a profile
Maximum Quality, Social or Small — each with a live estimate of the result. Every advanced parameter stays adjustable if you want to experiment.
Compare, keep or replace
Original and compressed side by side, with the real bytes saved. Keep both copies, or replace the original after the system asks you to confirm.
Compression profiles
Three presets, from invisible to aggressive
Start with a preset, then fine-tune format, quality, resolution, codec, frame rate and bitrate if you want to.
Maximum Quality
Smaller file, visually identical
Preserves dimensions, frame rate and metadata. Only reduces bitrate when it is safe to do so.
- Photos: quality 92, original resolution
- Videos: original resolution and frame rate
- HDR kept when the pipeline can preserve it
Social
Made for sharing
Caps very large videos at 1080p and optimises bitrate for messaging and social apps. Normal photos keep their resolution.
- Photos: quality 85, original resolution
- Videos: 1080p cap for very large sources
- HEVC/H.265 when the device supports it
Small
Aggressive, for experimentation
Resizes large photos to 1080p, lowers encoder quality and reduces video resolution and frame rate.
- Photos: 1080p resize, quality 65
- Videos: 1080p and a 30 fps cap
- Clearly labelled as aggressive in the app
What's inside
A storage analyzer and a compressor in one
Built with native iOS and Android encoders, so a 4K video never has to pass through JavaScript — or a server.
See where the space went
A dashboard of your library: totals, largest files and estimated savings before anything is compressed.
Originals are never modified
Compression always writes a new file. An original is deleted only through the explicit Replace action, after the system confirmation prompt.
Capture dates and metadata survive
Copies keep the original capture date, EXIF, camera info and — when you allow it — location metadata, so they sit next to the original in your gallery.
Built for real videos
4K and high-frame-rate sources, H.264 and HEVC re-encoding, HDR preserved when the pipeline can — and clearly reported when it can't.
Measurable results
Actual bytes saved, dimensions, bitrate and codec — plus PSNR for photos. Estimates turn into exact numbers after a real run.
No network needed
There is no upload step, because there is no upload. Sqizzi works with no connection at all.

Ask + confirm
Keep / Replace
Your originals are safe by default
By default Sqizzi only creates copies. When you want the space back, Replace deletes an original only after the compressed copy is safely saved — and only after the system asks you to confirm.
- Nothing is ever deleted automatically.
- Cancel the system prompt and the batch stops; saved copies stay.
- The results screen reports exactly how many bytes were reclaimed.
- Replacement is permanent once confirmed — keep backups you care about.
A look at the app
From "what's eating my storage?" to "done"
Browse largest-first, compress with a profile, then compare the numbers and the pixels.
Privacy
It collects nothing. That's not a promise — it's the architecture.
There is no account system, no analytics, no advertising and no server that receives your files. Everything happens inside the app, on your device.
- No sign-in, no profile, no device identifiers.
- No analytics, crash-reporting or tracking SDKs.
- Photos, videos and metadata never leave your phone.
- The only time we see anything from you is if you email support.

Questions
Good to know
Does Sqizzi upload my photos or videos anywhere?
No. Sqizzi contains no networking code and never sends your files, metadata or usage information anywhere. All scanning, compression and comparison happen on your device, which is why the app works fully offline.
Are my originals changed or deleted?
No. Compression always creates a new copy with the original capture date, so it appears next to the original in your gallery. An original is only deleted when you explicitly choose Replace — and even then, only after the compressed copy is saved and the system asks you to confirm. Never automatically.
How much smaller will my files get?
It depends on the source. Files that were never optimised can shrink by half or more without visible change, especially 4K videos and high-quality photos. Sqizzi estimates the result before you run it, then reports the exact bytes saved after. It never guarantees a specific saving.
Which formats are supported?
Photos: JPEG, HEIC/HEIF and PNG are re-encoded; WebP can be read. Videos: MOV and MP4 with H.264 or HEVC encoding. Live Photos, slow-motion videos and animated GIFs are detected and reported as not supported yet rather than being converted incorrectly. Whenever HDR, resolution, frame rate or metadata cannot be preserved, Sqizzi tells you.
What happens with photos stored in iCloud?
If a photo lives only in iCloud, iOS may need to download it before it can be compressed. That download is handled by Apple's Photos system under your iCloud settings — Sqizzi has no access to your Apple account and never uploads anything itself.
Is it really free?
Yes. Sqizzi is free, with no ads and no account. There is no paid tier that unlocks your data, because your data never leaves your device.
