Hey Product Hunt!
I built Alventra.io to solve a problem that kept bugging me: every time I needed to compress an image or merge a PDF, I’d end up on a site that wanted me to upload my files to some server, create an account, or pay after three uses.
So I built an alternative where everything runs in your browser. No file uploads. No server processing. Your images, PDFs, and text never leave your device.
Here’s what’s inside:
Image Tools — compressor, resizer, cropper, background remover, OCR
PDF Tools — merge PDFs, images to PDF
Text Tools — word counter, case converter, diff checker, markdown preview
Calculators — scientific, BMI, compound interest, loan EMI, percentage
Generators — QR codes, passwords, invoices, color palettes, lorem ipsum
Developer Tools — JSON formatter, regex tester, Base64, JWT decoder, hash generator
Date & Time — date difference, countdown timer, age calculator
Converters — unit converter, CSV to JSON, image format converter
37+ tools across 8 categories, all completely free. No premium tiers, no daily limits, no “sign up to continue.”
The privacy angle isn’t marketing — it’s how the tools are built. Everything is client-side JavaScript. I couldn’t see your files even if I wanted to.
