Mesuro is a free, fully-featured browser-based measurement tool for images and PDFs. Set a real-world scale, then measure distances, angles, areas, diameters and paths in any unit. Supports PDF import with page selection, edge snap for sub-pixel pre.
A startup from lausanne, Switzerland.

mesu.ro is a fully-featured, browser-based measurement tool for images and PDF files. No upload, no account, no installation required — everything runs locally in your browser. Measurement tools: Distance, diameter, angle (works without scale), area, path/perimeter, and text annotations. All measurements are displayed in real-world units with pixel fallback when no scale is set. Scale calibration: Draw a line over any known reference, enter its real-world value and unit (mm, cm, inches, feet, or any custom unit). The last used value is remembered across sessions. PDF support: Load PDF files directly — single-page PDFs open instantly, multi-page PDFs show a high-resolution page picker. Pages are rendered at ~430 dpi for precise measurement of technical drawings. Edge snap: Toggle sub-pixel edge detection (full Canny pipeline with Non-Maximum Suppression). The cursor locks onto detected contours with subpixel precision — ideal for engineering drawings and schematics. Perspective correction (Rectify): Place 4 corner points to correct perspective distortion before measuring. True homography with automatic aspect ratio recovery. Pan & zoom: Mouse wheel zoom up to 20×, click-drag pan, keyboard arrow navigation. A magnifier overlay shows a 5× live zoom around the cursor for precise point placement. Export: Annotated image (PNG, JPG, WebP), CSV data table, PDF measurement report with scale info and measurement table. Save/load full project files (.mesuro) to resume work later. Interface: 5 languages (EN, FR, ES, DE, IT), dark theme, keyboard shortcuts for all tools, undo (50 levels), draggable measurement labels.

mesu.ro is the only tool that combines: Browser-based, zero friction — open URL, drop image, measure. No account, no upload, no install PDF import with page selection — direct load, rendered at 430dpi, no conversion step needed Edge snap — Canny edge detection with NMS and subpixel interpolation, running entirely client-side in JS Perspective correction — full homography, not just a crop or rotate Complete measurement suite — distance, diameter, angle, area, perimeter, notes, all calibrated to real-world units Privacy by design — images never leave the device, no server, no telemetry on the image data Multilingual — 5 languages out of the box
mesu.ro wins on speed of access and zero friction. No download, no signup, no payment, no learning curve. For anyone who measures images occasionally — checking a dimension on a photo, measuring a PDF plan, verifying a part from a SEM image — the barrier to use is essentially zero.
Engineers, technicians, and researchers who receive images or PDF drawings and need to extract real dimensions from them. PCB designers checking component placement from a photo. Mechanical engineers measuring a part from a SEM or microscope image. Architects verifying dimensions on a scanned floor plan. They know what a scale is, they measure in mm, and they need a result fast without opening a dedicated software suite.
mesu.ro was born out of frustration. As an engineer, I kept needing to measure things in images — parts, drawings, microscope photos. Every existing tool was either a $500 desktop app, a complex scientific suite, or a basic online tool that only did distance. So I built a single HTML file that did exactly what I needed. No server, no upload, no account. Just drop an image and measure. I added PDF support, edge snap, perspective correction, multilingual interface. At some point I realized I'd accidentally built the tool that should have existed all along. I put it online. A stranger sent $5 on Ko-fi three days later. That was enough.
A single HTML file. That's the whole stack — no framework, no build tool, no dependencies bundled locally. Everything runs in the browser. The technologies inside that file: Vanilla JavaScript — all measurement logic, canvas rendering, pan/zoom, undo, project save/load HTML5 Canvas API — drawing the image, measurements, magnifier overlay, snap indicator PDF.js (Mozilla, via CDN) — PDF parsing and high-resolution page rasterization jsPDF (via CDN) — PDF report generation client-side Canny edge detection — implemented from scratch in JS (Gaussian blur, Sobel, NMS, hysteresis, subpixel interpolation) Umami Analytics — privacy-friendly, self-hosted compatible, no cookies Formspree — feedback form backend, zero server required GitHub Pages — hosting, free, zero infrastructure to manage
We have collected here some useful links to help you find out if Mesu.ro is good.
Check the traffic stats of Mesu.ro on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of Mesu.ro on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of Mesu.ro's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of Mesu.ro on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.
