BUILT FOR PEOPLE
WHO DON'T TRUST
THE CLOUD.
SQUEZR IS A BROWSER-NATIVE PRIVACY TOOLSET. ONE PERSON. ONE CONSTRAINT: YOUR FILES NEVER LEAVE YOUR DEVICE.
The frustration
Every image compressor, every metadata editor, every "free online converter" on the internet asks you to do the same thing: upload your file to their server. You hand over your photos, your documents, your files, to infrastructure you've never seen, run by companies whose privacy policies you've never read, just to get a smaller JPEG back.
And the trust is implicit. You don't get to audit what happens to your file after it lands on their server. You don't know if it's retained, analysed, or indexed. You just hope it isn't.
Squezr was built to eliminate that trust requirement entirely. The tools are genuinely useful. But the constraint that drives every decision is simple: no file ever leaves your browser.
Who built this
Squezr is a solo project. One person, one codebase.
The person behind it is a cybersecurity enthusiast. That background is not incidental: it is the entire reason this tool exists. When you study how data leaks, how metadata exposes people, and how "secure" third-party services get breached, you stop casually uploading files to random servers. You also start building alternatives.
Squezr is that alternative. Every design decision, from the client-side architecture to the 3-device session cap, comes from the same place: knowing what can go wrong when you trust too easily.
How it works
Every algorithm in Squezr (compression, hashing, metadata stripping) runs entirely inside your browser tab using modern Web APIs: the Canvas API, Web Workers, and the FileReader API. There are no server round-trips for file processing. Nothing is buffered or cached on our end.
When you drop a file, it loads into browser memory. When you close the tab, it's gone. We never see it.
- No uploads: files are processed in-browser via Web APIs, not sent to a server.
- No retention: we have no file storage. There is nothing to breach, subpoena, or accidentally leak.
- Verifiable: open your browser DevTools, go to the Network tab, then run a tool. You'll see zero file-upload requests.
- Accounts are optional: free tools require no sign-in. Pro accounts store only your email and subscription status. Nothing about the files you process.
The tools
Five tools, all client-side:
- CompressorCompress JPEG, PNG, and WebP images to a target file size. Batch-ready for Pro users.
- Hash-MorphAppend four random bytes to any file's tail to produce a new SHA-256 fingerprint, without altering visible content.
- PureHashStrip EXIF, IPTC, and XMP metadata from images and compare SHA-256, SHA-1, and MD5 hashes before and after.
- EchoDetectDetect structural similarity between two files using CTPH fuzzy hashing, even if they've been slightly modified.
- Metadata StripperRemove embedded metadata from JPEG, PNG, WebP, and MP3 files in bulk. No upload required.
What's next
Squezr is an active, independent project. The roadmap is guided by one rule: every new tool must run entirely in the browser, with no file leaving the device.
We're expanding to more file types, refining batch workflows, and improving the Pro experience. Nothing is promised on a fixed timeline. The project is very much alive.
If you have a tool you'd find useful or a bug to report, send an email. It goes directly to the person who wrote the code.
