Image Compressor & Cropper
Crop images to perfect social media ratios, choose your export format, and shrink file sizes for web uploads. Runs entirely in your browser — your images are never uploaded anywhere.
Drag & drop images here, or click to browse — multiple files welcome
JPEG lets us hit your target size precisely by adjusting quality.
Privacy note: re-encoding an image this way also strips hidden metadata like GPS location and camera info automatically — it's a side effect of how the crop/compress process works, not an extra step.
Batch: multiple images at once
10 crop ratios + custom
JPEG, PNG or WEBP export
Strips hidden photo metadata
Caption Formatter
Format social media captions with clean spacing, extract hashtags, and beat character limits.

Password Generator
Create strong, secure, and random passwords instantly — generated with your browser's cryptographic random number generator.
—
Built from the EFF's 1,296-word passphrase list — each word adds about 10.3 bits of real entropy.
This sends only the first 5 characters of a scrambled (hashed) version of your password to the free, well-established HaveIBeenPwned API — never the real password, and never the rest of the hash (it's mathematically impossible to reconstruct your password from what's sent). This is the one deliberate exception to "nothing ever leaves your device" anywhere on this site, and it only runs when you click the button above.

About UtilityKit
Hi! I built UtilityKit because I was tired of using online tools that are full of spammy ads, force me to sign up, or ask for money just to do basic tasks.
UtilityKit is a minimalist toolkit designed to solve everyday problems—like compressing images for online forms or fixing social media captions—without the hassle. Every tool here, including QR code generation, runs entirely in your browser. Your data is never uploaded or tracked.
Privacy Policy
At UtilityKit, your privacy is our top priority. This website operates 100% on the client-side.
No Data Collection: We do not collect, store, or transmit any personal data, images, text, or passwords. Everything — including QR code generation — stays and runs in your browser.
Saved Settings: A few non-sensitive preferences (QR colors/size/format, password character-type toggles) are remembered on this device between visits, purely for convenience. Your generated passwords, passphrases, and any content you type are never saved.
Optional Breach Check: The Password Generator has an opt-in check (off by default) against HaveIBeenPwned's breach database. When you explicitly enable it and click "Check," only the first 5 characters of a scrambled version of the password are sent — never the real password.
Analytics: We use anonymous Google Analytics to see site traffic. You can turn this off below at any time.
