Your files never leave your device. All image conversions, PDF processing, and file manipulations happen directly inside your browser using JavaScript. We do not upload your files to any server — which means your personal documents, photos, and data are always under your control. No sign-up, no data collection.
Because your files are processed locally in the browser, there is no waiting for a server to respond. Conversions and edits are near-instant. Our tools are optimized for performance so that even large PDF files and high-resolution images are handled quickly and smoothly.
OneTooly is fully responsive and works on desktop computers, laptops, tablets, and smartphones. Whether you are on Windows, Mac, Linux, Android, or iOS, you can access all our tools through any modern web browser — no app installation needed. We also offer a free Android APK for quick mobile access.
Stop jumping between different websites for every task. OneTooly brings together image converters, PDF editors, QR code generators, file compressors, and creative tools all under one roof. Our growing library means you will always find the tool you need without leaving the site.
Forget downloading desktop applications or installing browser extensions. OneTooly tools run entirely in your web browser using modern web standards. This makes them lightweight, always up to date, and accessible from any device without any setup. Just open the page and start working.
Getting your files converted, compressed, or edited is simple. Here is all it takes:
Browse through our categories — Image Tools, PDF Tools, or Other Tools — and pick the one that matches your task.
Click the upload area or drag and drop your file directly onto the page. Most tools accept files up to several MB in size.
Click the action button (Convert, Compress, Generate, etc.). Your browser processes the file instantly — no server upload needed.
Once processing is complete, a download button appears. Click it to save the result to your device. That is all there is to it!
Not sure which format to use or why you need to convert? Here is a quick guide to the most common file formats our tools work with.
PNG is a lossless image format, meaning it preserves every pixel of your original image without any quality loss. It supports transparent backgrounds, making it ideal for logos, icons, and graphics used in web design. PNG files are generally larger than JPG files.
JPG is a lossy compression format best suited for photographs and complex images where some quality loss is acceptable in exchange for a much smaller file size. JPG does not support transparency, but it is the most widely compatible format across all devices and platforms.
WEBP is a modern image format developed by Google that provides superior compression compared to PNG and JPG. A WEBP image can be up to 30% smaller than an equivalent PNG or JPG while maintaining similar visual quality. WEBP supports both transparency and animation.
PDF is the standard format for sharing documents because it preserves formatting across all devices and operating systems. Whether you open a PDF on Windows, Mac, Android, or iOS, it looks exactly the same. Widely used for contracts, reports, e-books, and official forms.
SVG is a vector-based image format defined by mathematical equations rather than pixels. This makes SVG images infinitely scalable — they look sharp at any size, from a tiny favicon to a giant billboard. SVG is perfect for logos, icons, and illustrations used in web and print design.
