One place for everyday file tasks and developer tools — free, fast and private.
For work & study
Merge reports and invoices into one PDF, convert a Word document for sharing, or compress an image to fit an upload limit — no software to install.

Got questions? We have answers.
Most conversions of everyday files finish in a few seconds. Large videos, long documents and OCR take longer because every page or frame has to be processed. In-browser tools such as the JSON formatter respond instantly.
Only for as long as needed. Uploaded files and results are kept temporarily so you can download them, and are deleted automatically — download links expire after 15 minutes and leftover files are cleaned up regularly. We never read, share or sell your files.
Yes. Every tool works in mobile browsers on Android and iPhone as well as on tablets and computers — there is no app to install.
No. Every tool on FilesSwift is completely free to use, with no sign-up, no subscription and no watermarks added to your files.
FilesSwift supports a wide range of formats — PDF, Word, Excel, PowerPoint, JPG, PNG, WebP, MP3, WAV, MP4 and more — plus data formats like JSON, XML, YAML and CSV for developers.
Many developer and text tools — the JSON formatter, Base64 encoder, case converter, hash generator and others — run entirely in your browser, so nothing is uploaded. Once a tool page has loaded, it keeps working even if your connection drops. File conversions need an internet connection.
There is no daily limit. 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), and a fair-use rate limit protects the service from automated abuse.
Yes. Add Text to PDF, Header & Footer, PDF Watermark, Bates Numbering and TXT to PDF draw Gujarati and Devanagari (Hindi, Marathi) text with proper fonts, so letters and matras appear correctly instead of empty boxes.
You get a clear message that says what went wrong and what to do — for example that a PDF is password-protected, damaged, or a scan without text — instead of a vague error. Your file is still deleted automatically.
Use the Contact or Feedback page. Tell us the tool, the file type and the exact message you saw. After a conversion you can also rate the result, which helps us see which tools need work.
