Free browser-based tools
Lightweight, browser-first tools built for technical workflows. Zero signups, zero server uploads, and no bloat.
Most tools run entirely in your browser. Nothing uploaded, nothing stored.
Open a tool and start using it immediately. No accounts, no email required.
Every tool tells you exactly where your data goes — browser, local AI, or server.
Choose a tool for your workflow and get started instantly — no signup, no installation, and no unnecessary steps.
Format, validate, and minify JSON instantly — see exact error line numbers, no signup, nothing uploaded.
Test a regular expression against text live — every match highlighted in place, capture groups broken out.
Draw bounding box annotations on your images and export as YOLO, COCO, Pascal VOC, or VIA CSV. Autosaves locally — right in your browser.
Upload a GeoJSON, KML, GPX, or lat/lon CSV file and see it rendered on an interactive map instantly — no signup, nothing uploaded.
Turn a CSV into a bar, line, area, scatter, pie, or histogram chart — pick columns, download as PNG.
Decode a QR code from a photo or screenshot — the detected code outlined on the image, nothing uploaded.
Combine multiple PDFs into one — reorder files first, download a single merged file.
Pick a preset and see a live before/after preview — no guessing what quality setting to use.
Download a plain folder, double-click it open, and it runs — no site, no server, no connection, ever again. Flip the switch and see for yourself:
Runs entirely in your browser, right now.
Download the Image Annotator as a plain folder — double-click to open, no install, works with zero internet connection.
Tuliq Offline's first tool: scan a real folder on disk for YOLO dataset problems — no browser file-count limits, no upload.
Step 1
Click any tool — no signup, no download, nothing to install.
Step 2
Convert, annotate, calculate, or process right there in the page.
Step 3
Download or copy your output instantly. Nothing was ever uploaded to a server.
Format converters, encoders, generators — the small utilities you reach for mid-project and don't want to install a package for.
Bounding box conversion, annotation, and dataset utilities built by someone who actually works with YOLO, COCO, and VOC formats daily.
Image, file, and data tools that just work — without an account wall between you and the thing you're trying to do.
In-depth reading on how to actually use these tools — formats, workflows, and comparisons, not just definitions.
What YOLO, COCO, Pascal VOC, and VIA CSV annotations actually contain, how their coordinate systems differ, and where conversion and verification fit in a real object detection workflow.
What GeoJSON, KML, GPX, CSV, WKT, TopoJSON, and Shapefile actually contain, the coordinate-order bug that trips up almost everyone, and where conversion and verification fit in a real geospatial workflow.
What Tuliq's 🔵 Local AI badge actually means — a real model, downloaded once, running entirely on your device — and how that's different from uploading to a cloud AI service.
What bar, line, pie, histogram, scatter, box plot, and heatmap charts each actually answer — and which of Tuliq's chart tools fits which question.
Unfold turns an idea, a dataset, or a piece of research into an animated presentation that lives on the web — for researchers, founders, educators, and analysts.
