About
An online file converter with no sign-up: fast tools for images, video, GIF and documents with automatic file deletion.
Updated: November 2, 2026
Why we built it
File conversion should take seconds, not require installing software, buying a subscription or creating an account. The project brings popular format pairs together in one place, from JPG to PNG to PDF to DOCX.
How the service works
Images are converted in the browser, so files never leave your device. Video, GIF and documents are processed on the server in an isolated queue with a single concurrent job. Results are deleted automatically after download or within an hour.
Privacy
We do not create profiles or store conversion history. Rate limiting protects the service from abuse. Advertising and analytics scripts load only after consent.
Technology
The site is built with Next.js and TypeScript. Video uses ffmpeg, documents use LibreOffice, Poppler and pdf2docx, images use the Canvas API and sharp. The queue runs on BullMQ and Redis.
