About Rexme

Rexme is a collection of fast, free utilities that run entirely in your web browser — built for people who want results without uploading files or creating accounts.

Why we built Rexme

Most online tools ask you to upload documents to a remote server, wait in a queue, and hope your data is deleted afterward. Rexme takes a different approach: processing happens on your device using modern browser APIs (Canvas, Web Crypto, PDF libraries, and more).

That matters for contracts, ID scans, JWT tokens, client SEO drafts, and anything else you would not email to a stranger. Speed is a side benefit — there is no round trip to a server for the core workflow.

What you can do here

PDF tools — images to PDF, merge PDFs, export pages as images.
Image tools — compress, resize, crop, and convert formats.
SEO tools — SERP preview, meta tags, schema markup, sitemaps, robots.txt, UTM builder.
Developer tools — regex tester, JWT decoder, hash generator.
And more — text utilities, JSON formatter, Markdown editor, QR codes, passwords, colors, unit conversion.

Browse by category from the home page or use the top navigation on any tool page.

Privacy by design

We do not operate user accounts for these tools. We do not receive your files or pasted text for processing. Analytics, if enabled on a deployment, should be configured by the site operator — see our privacy policy for details.

Some tools may save preferences (for example SEO admin overrides or UTM history) in your browser’s localStorage only on your device.

Limitations

Browser-based tools depend on your device memory and a modern browser (Chrome, Edge, Firefox, Safari). Very large PDFs or huge images may be slow or fail on low-memory devices. Features like JWT signature verification belong on a server with your keys — our decoder is for inspection only.
