About

BoringX is 40 small tools that each do one dull job: merge a PDF, format some JSON, strip the location from a photo. Everything runs in your browser. There is no server doing the work.

What it is not

• Not an account. There is nothing to sign up for.
• Not limited. No daily caps, no file-size paywalls, no watermarks.
• Not tracking you. There is no analytics script.

The Sandbox

Most text and data tools here are small chains of blocks. The Sandbox lets you rearrange those blocks into your own tool, including a Custom JavaScript block that runs in an isolated Worker. You can save the result in your browser or share it as a link; the whole recipe is in the link, so it opens and runs with no server.

Honest limits

• Heavy tools (background removal, OCR) download their engine from this site the first time, then work offline. They are slower than a server with a GPU.
• PDF compression is either a lossless tidy-up, or a lossy flatten to images. There is no magic third option in a browser.
• AVIF output depends on your browser. Where it cannot encode AVIF, the tool says so.
• OCR is English only.
