One window for the files that clog up inboxes and upload forms. Anything else you drop in is copied along untouched, so folders come out complete.

.svg .svgz02 / Features
No accounts, no upload limits, no watermarks. Just a small, fast tool that does one job properly.
Drop hundreds of files at once. Crunchy works through them in parallel on every core you have.
Drop a folder and Crunchy walks it recursively, rebuilding the same folder structure in the output.
Get lighter copies side by side, or everything packed into a single ZIP ready to email.
Light keeps quality pristine, Balanced is the sweet spot, Maximum squeezes out every last byte.
Remove EXIF, GPS location, authors and editing history. Photos are rotated upright first.
Crunchy only writes new copies and never overwrites anything, not even its own earlier output.
Checks a tiny manifest and updates itself in one click. No store, no account, no nagging.
Files never leave your PC. No uploads, no telemetry. It works just as well on a plane.
03 / How it works
Drag files or whole folders onto the window, or click to browse.
Pick a level, separate files or one ZIP, and where to save.
Hit Compress and watch the savings add up, file by file.
Private by design
Everything runs locally. Crunchy has no servers to upload to, no account to sign into and no analytics to report back. The only request it ever makes is a peek at a tiny update file.
04 / FAQ
Something else? Say hi at h190k.com.
Yes. Crunchy is free to download and use: no ads, no accounts, no trial and no paywalled levels.
Never. All compression happens locally on your PC and your files never leave it. Crunchy writes new, smaller copies and never modifies or overwrites your originals. The only thing it ever fetches from the internet is a tiny update file, /update/latest.json.
Windows 10 and Windows 11, 64-bit (x64).
Crunchy isn't code-signed yet (certificates are expensive for an indie app), so SmartScreen may say it "protected your PC" the first few times. Click More info, then Run anyway. If you want to be sure the file is genuine, compare its SHA-256 with the one on the download page.
It depends on what's inside. Scanned PDFs, photo-heavy decks and camera JPEGs often shrink by 50–80%. Files that are already well compressed may barely move. If Crunchy can't make a file smaller, it keeps the original bytes and marks it Already optimized.
By default they're copied into the output unchanged, so a folder you drop comes out complete. You can switch that off to only get the compressed files.
Crunchy checks a small manifest on this site. When a new version is out it offers to download it, verifies the SHA-256 checksum, and runs the installer for you.
