Personal Tools
Passport photos, PDFs, and everyday calculators that run on this device. Nothing uploaded.
Why keep personal files on this device?
A passport photo, a scanned lease, or a bank export is not a puzzle for a search box. The answer only exists once your file is in the tab, and sending that file to a converter you do not run is how identity pictures and account numbers leave the house. Jobs like these belong on the device that already holds the original.
This category is for civilian files, photos, and calculators. Hardware tests, developer parsers, and engineering math stay in their own lanes. School and household calculators can sit here later if they need your numbers rather than a one-line formula; nothing in this writeup pretends those tools already exist.
Every tool in the group runs in the browser with no account. Load the page, and the work stays in that tab. You can disconnect after load for tools that do not fetch an optional library, and you never create a login to download a result.
No. CapyToolkit doesn't upload or store the files you drop on these pages. Processing runs in your browser tab.
No. There is no sign-up, no login, and no usage cap tied to a plan.
Personal files, photos, and calculators that need your own input. Hardware diagnostics, developer parsers, and engineering math live in other categories.
Once the page has loaded, work that does not fetch an optional library keeps running if you disconnect. A status line tells you when a library is still loading.
A cloud converter has to receive the file to change it. Identity photos and household documents should not take that trip when the same crop or total can run locally.
Yes, in a modern mobile browser. A larger screen makes cropping easier, but the page is built to work at a phone width.
