About FilesSwift
Free, practical tools for everyday file, document and developer tasks — explained honestly, with clear limits.
Our Mission
Converting a PDF, shrinking a photo for an upload form or tidying a JSON response should take seconds, not a software install. FilesSwift puts those everyday jobs in one place, with tools that do one thing well and pages that explain exactly what each tool does — including what it cannot do — so you know what to expect before you upload anything.
Fast and simple
No account, no install and no watermark. Most tasks finish in a few seconds; large videos and long documents take a little longer.
Private by design
Text and developer tools run in your browser, so your data never leaves your device. Uploaded files are deleted automatically, normally within 15 minutes.
Honest about limits
Each tool page explains its supported formats and what the tool cannot do, and when a file cannot be processed you get a clear reason instead of a vague error.
What FilesSwift Offers
FilesSwift brings together more than 100 free online tools in one place, so you don't need to hunt for a different website for every task. Our tools fall into a few families:
- Document & file converters — convert between PDF, Word, Excel, PowerPoint, images, audio and video formats.
- PDF tools — merge, split, compress, rotate, protect, unlock, watermark, add page numbers and more.
- Image tools — compress, resize and convert JPG, PNG, WebP and other image formats.
- Developer & data tools — format, validate and convert JSON, XML, YAML and CSV; encode/decode Base64 and URLs; and escape code.
- Everyday utilities — generate passwords, UUIDs and hashes, decode JWTs, test regular expressions, count words, remove duplicate lines and compare text.
How It Works
Most of our developer and text tools run entirely in your browser, which means your data never leaves your device — ideal for sensitive content. File conversions that need heavier processing — PDF, Office documents, images, audio and video — are sent to our server over an encrypted HTTPS connection and processed with established open-source engines such as LibreOffice, Ghostscript, qpdf, FFmpeg and sharp. Uploaded and converted files are deleted automatically, normally within 15 minutes. There are no accounts to create and no watermarks added to your files. Each tool shows its maximum file size on the upload box — for example 50 MB for images, 200 MB for audio and 500 MB for video.
Who It's For
FilesSwift is used by students, office workers, designers, writers and developers alike. Whether you need to quickly merge a stack of PDFs before a deadline, shrink an image so it fits an upload limit, tidy up a messy JSON response from an API, or clean up a mailing list, our goal is to help you finish the task in a few clicks and get on with your day.
We're continually adding new tools and improving the ones we have. If there's a tool you'd like to see, we'd love to hear from you on our contact page.
