FathomFree file tools, right in your browser
No install, no account. Your files never leave your device: everything on this page runs inside your browser, and nothing is uploaded anywhere. For the long list (Word and Excel conversion, OCR, video, the AI assistant, redaction, drives and more) get the free app.
Add your files once, then use them in any tool below.
Find words inside your files
Looks inside text and code files, PDFs, Word (.docx), PowerPoint (.pptx), Excel (.xlsx), OpenDocument, e-books (.epub) and web pages, all at once. (Words inside pictures need OCR: the app does that.)
PDF tools
Protected (password) PDFs are not supported here. Page numbers and watermarks use plain Latin letters.
Convert, shrink and turn pictures
Saving again also removes hidden camera and location details (EXIF) from the picture. Transparent areas turn white in JPG.
Zip files
“Open” lists what is inside a .zip, so you can save single files without unpacking everything.
Checksums
A checksum is a fingerprint of a file. If two files give the same fingerprint, they are identical. Handy to check a download.
Hex view
Shows the raw bytes of the first added file.
Data and spreadsheets
Excel files are read for their values (formulas show their last calculated result). Old .xls files need the app.
Honest limits: this page works on your device's memory, so very large files may not fit, and it cannot do what needs programs on your computer: Word/Excel/PowerPoint conversion, e-books, RAR, OCR and handwriting, video, speech, redaction, drives, sync and the AI assistant. The free app has all of that, with no size limits.
