About ToolKitly

ToolKitly is a set of free, no-nonsense tools for the jobs that come up constantly: compressing an image, merging a couple of PDFs, cutting out a background, formatting some JSON.

Everything runs in your browser

Most online file tools work by uploading your file to a server, processing it there, and sending it back. That works, but it means handing your documents to a stranger, waiting on the upload, and trusting that the file is deleted afterwards.

ToolKitly takes the other approach. Every tool runs as code inside your browser tab, using the same APIs that power image editing and PDF viewing on the web. Your file is read into memory, processed, and handed back - all on your own machine.

What that means in practice

This design has concrete consequences, good and bad, and it is worth being clear about both.

Your files stay private, because they are never transmitted anywhere
There is no upload wait, so small and medium files are often faster than a server-based tool
It works offline once the page has loaded
Speed depends on your device rather than our hardware, so very large files can be slow on an older phone
A few things are genuinely impossible in a browser - Word to PDF conversion, for instance, needs a full office engine

No accounts, no watermarks, no daily limits

There is nothing to sign up for and nothing to unlock. Since we do not run servers to process your files, there is no per-file cost to recover, which is what usually drives the sign-up walls and daily caps on tools like these.

Honest about limitations

Some tools cannot do everything the name suggests, and we say so on the page rather than hiding it. PDF compression is the clearest example: a scanned document shrinks dramatically, but a text-heavy PDF barely moves, because its size comes from embedded fonts rather than images. Where a trade-off exists, the tool explains it and lets you choose.

The same goes for results. If compressing a file would make it larger, you get your original back with a note saying so, rather than a "compressed" file that is bigger than what you started with.

What is next

The tool list grows over time. The current focus is covering the common image, PDF and developer tasks well rather than shipping a hundred half-finished tools.
