LocalLab is a suite of file processing tools that run entirely in your browser: images, videos, audio, PDFs, text, and some utilities like QR codes and passwords. Everything happens right on your machine, and files are not sent to any server.

Problem solved
If you want to compress an image, merge several PDF files, or trim a video clip, you usually have to install heavy software, or upload files to a strange website, often accompanied by ads, file size limits, watermarks, and the worry of document exposure. LocalLab allows you to do these tasks quickly and for free, without files leaving your machine.

Main features

• Images: batch compress, resize, cut and rotate, merge images, insert watermark, remove metadata (location, date taken), obscure sensitive information, remove image background.
• Video: cut, compress, add text on the timeline, screen recording, extract images from video, convert to GIF.
• PDF: merge, split and arrange pages, compress, sign, page numbering, convert back and forth with images.
• Audio and documents: extract audio from video, record audio, convert formats, word count, remove Vietnamese diacritics, convert XML invoices to Excel.
• Utilities: create and read QR codes, create strong passwords.

Who should use it
Office workers and accountants who need to send lightweight files and invoices; online sellers processing product images; students preparing assignments and submitting documents; content creators making short video clips; developers and designers needing icons and color palettes.

How to get started
Open the website, select a tool, drag and drop your file to get started: no installation, no registration. It is recommended to use the latest version of Chrome or Edge for the smoothest video tool experience. The interface is available in both Vietnamese and English, with light and dark modes, and is usable on mobile devices.

What sets it apart
Unlike many online file processing sites, LocalLab does not upload files, has no usage limits, no watermarks, and does not require an account. Since it runs on your machine, the speed depends on your device, but in return, you retain full control over your data.
