Compress an image to 100 KB without guessing
A measured sample run, two reusable practice images, and a way to check size, transparency, and legibility before downloading.
When PDF compression makes a document larger
Download a text PDF and an image-only PDF, compare measured reference outputs, and see why searchable text matters.
Why two word counters can give different answers
Exact examples for Chinese, hyphenated words, emoji, blank lines, and the reading-time estimate used by OmniKit.
A time zone conversion needs a date, too
New York–Shanghai examples show seasonal offsets, skipped times, repeated times, and crossing into the previous day.

What should we build next?
OmniKit grows around real everyday needs.
Choose a tool by what the result needs to do
An upload limit, a searchable document, and editable text call for different workflows. Use image compression for smaller image files, PDF organization for page changes, and OCR when you need a draft of text from a scan. The practical guides explain settings, repeatable inputs, and checks before you replace an original.
Image, PDF, and text tasks run on your device. The complete directory also includes video downloads, recording, audio, developer, and everyday tools. Public-video downloads use a server queue; see the tool page and privacy policy for that processing boundary.
