Small, private, useful web tools from 100ideas — calculators, compressors, converters and more.
Free, instant, privacy-first calculators — Schengen, FIRE and TDEE.
“We asked: what if the most useful calculators lived in one clean, instant, private place? No accounts, no tracking, just the number you needed thirty seconds ago. That is why we made this.”
A simple way to work with documents.
“We kept asking: what if the PDF tool disappeared into the background, leaving only the document and the one action you wanted? Why did we make this — because a document task should take seconds, not a tutorial.”
Compress JPG and PNG images online — processed locally.
“We asked: why should compressing an image require uploading it anywhere? The browser can do this locally — so why not build a compressor that never sees the network at all? That is why we made this.”
Explore AI models through a simple interface.
“We asked: why should comparing AI models require code? We wanted a place where a creator could put the same question to several models and feel the difference in their answers. That is why we made this.”
