Html Tools
1088 free browser tools — JSON formatter, JWT decoder, Base64 encoder, image compressor — all client-side, no sign-up.
Bookmark this for the privacy-first errands, not the 1088 headline. A JWT decoder that never uploads your token, an image compressor that never touches a server and a hash generator that runs on a file without a round trip are genuinely useful for anyone working with secrets or on a restricted machine. If you need conversions wired into a build pipeline, a schema validator with guaranteed spec coverage, or a shared team snippet library, a dedicated tool wins — those aren't in this catalog. Use it as a first stop, not a toolchain.

About Html Tools
Html Tools, published as WebUtils, is a collection of 1088 front-end utilities across 35 categories that run entirely inside your browser tab. Nothing is uploaded: the JSON formatter locates and highlights syntax errors locally, the JWT decoder prints header, payload and signature without sending your token anywhere, and the image compressor shrinks files before they ever leave your machine. The catalog is heaviest on developer and designer work — 205 development tools, 65 text tools, 59 generators, 57 media tools, 54 calculators, 48 design tools and 44 AI tools — with smaller groups for security (13), privacy (14), SEO (9), finance (21), data (30) and 22 mini-games. Named entries include a regex tester with match highlighting and capture groups, JSON-to-YAML conversion with formatting, a Markdown editor with GFM preview and HTML export, a hash generator covering MD5 through SHA-512, a Cron expression builder, a UUID v4/v7 and ULID generator with batch mode, a password generator with strength detection, an in-browser image compressor, and a colour picker with contrast preview. Navigation is deliberately flat: type '/' to focus search, star a card to favourite it, or drill into a category. The site is plain HTML/CSS/JS with no build step, so it loads on locked-down or offline machines where installs are blocked. What you do not get is a workspace — the site documents no account, no sync and no shared library.
Behind the Verdict
The value here is the deployment model, not the count. Every tool is front-end only, which means the JSON formatter's error location, the JWT decoder's header/payload/signature view, the regex tester's capture groups and the image compressor's output all happen in your tab. For anyone handling tokens, keys or client files, that removes the usual question of whether a random utility site is logging what you paste. It also means the collection works without a network connection once loaded, which matters on air-gapped or locked-down machines where you can't install software. Breadth is real and skewed toward developer and designer chores: 205 development tools, 48 design tools, 57 media tools, 59 generators, 54 calculators, plus a structured AI prompt generator built on a CREATE framework. The practical picks are the unglamorous ones — Base64 for text and files, Base64 image conversion, URL and HTML entity codecs, text diff with inline highlighting, timestamp and timezone converters, a Cron builder, UUID v4/v7 and ULID with batch mode, a password generator with strength detection, a colour picker with contrast preview, and an aurora CSS gradient generator that exports plain CSS you can paste into a stylesheet. The honest weaknesses follow from that same design. 1088 entries produced as plain HTML/CSS/JS across 35 categories means polish and depth will be uneven — some entries are near-duplicates (several colour pickers, several Lorem Ipsum generators, several text-diff cards), and duplicates are not depth. Nothing here describes an account layer, cross-device sync, a shared workspace, approval trails or audit logs, so it is unsuitable as a team system of record. The only integrations-style listing in the scrape is absent, and the docs and changelog pages were not reached this run, so treat questions about pipeline hooks and release cadence as unanswered rather than settled. Keep it for the private, zero-setup lookup; keep your pipeline tooling somewhere else.

Real-world workflow fit
Concrete scenarios for the personas Html Tools actually fits — and what changes day-one when you adopt it.
You paste a JWT from a failing request into the decoder to read the header and payload claims, after first checking the signature section to confirm the algorithm.
Outcome: You spot the expired claim without the token leaving your laptop, then re-run the request with a fresh one.
You run a client CSV through the text-diff tool to compare two exports, then compress a screenshot in the image compressor before attaching it.
Outcome: Both files stay local — nothing is uploaded, and nothing needed installing on a machine where installs are blocked.
You build an aurora gradient with the CSS generator, export the plain CSS, and check the text-on-background contrast with the colour picker's contrast preview.
Outcome: You paste the gradient and a pass-on-contrast colour pair straight into the stylesheet without opening a design app.
Use Cases
- Generate a UUID v4/v7 or ULID, or a random password, while offline or on a restricted machine
- Decode a JWT during API debugging without sending the payload to a third-party server
- Convert HTML to Markdown or JSON to YAML without sending data online
- Check the contrast ratio of two colours for accessibility
- Compress an image locally before uploading it to a website
- Test a regex with live match highlighting and capture groups
- Build a Cron expression visually instead of writing it from memory
- Generate an aurora CSS gradient background and export the CSS
Limitations
- Everything is rendered client-side, which is the point and also the ceiling: the site documents no account, no backend and no shared library, so there is no cross-device sync, no team workspace and no audit trail for anything you process.
- The catalog spreads 1088 entries across 35 categories, and the overlap is visible — multiple colour pickers, several Lorem Ipsum generators and several text-diff cards — so depth and polish vary between entries.
- Do not treat this as an accuracy-guaranteed reference for regulated conversions.
- The docs/developer pages, changelog and integrations pages were not reached in this run, so nothing here should be read as a statement about pipeline hooks, release cadence or integration coverage.

Setup time & first value
How long it actually takes to get something useful out of Html Tools — broken out by persona, not the marketing-page minute.
Nothing to install or configure — open the page and start typing; pressing '/' focuses search so you can jump to the JSON formatter, JWT decoder or image compressor in seconds. Expect under a minute to first result for a one-off lookup, and a little longer the first time you work through category drill-down to find the less obvious entries.
Switching to or from Html Tools
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a server-side formatter or encoder site: paste the same input into the local JSON formatter or Base64 tool and keep the result on your machine.
- →From a desktop hash utility: switch to the in-browser hash generator for MD5, SHA-1, SHA-256 and SHA-512 on text or files.
- →From a spreadsheet colour workflow: replace manual hex picking with the colour picker's RGB/HSL/HEX output and contrast preview.
- ↗To a pipeline-integrated formatter or validator: move recurring conversions into a build-step tool when you need them automated.
- ↗To a team snippet or workspace product: move favourites and shared utilities when cross-device sync becomes a requirement.
- ↗To a dedicated image pipeline: move compression into your asset build when repeatable, scripted output matters.
