Shrink MP4, MOV, AVI and MKV files for email, messaging and the web — locally on your own machine. No file-size ceiling, no slow uploads, and your footage never leaves your device.

Frequently asked questions
What 1FileTool can do — and how it keeps your files private.
Can I convert PDF to Word and Word to PDF offline?
Yes. 1FileTool converts PDF to editable Word (DOCX) and Word back to PDF entirely on your Mac or PC — including OCR for scanned PDFs and batch conversion for whole folders. Nothing is uploaded.
Does 1FileTool merge, split and compress PDFs?
It does. Merge dozens of PDFs into one, split by page or range, and compress large PDFs to shrink file size for email — all processed locally, with no watermarks and no daily upload caps.
Can I compress video and convert MP4 to MP3 without uploading?
Yes. 1FileTool compresses video, converts between MP4, MOV, AVI, MKV and more, and extracts audio such as MP4 to MP3 or WMA to MP3 — using a bundled ffmpeg engine that runs on your own machine.
Is there a free file converter in 1FileTool?
Every one of the 265+ tools is free to use for up to 8 files per day, including the image converter, video converter and PDF tools. Upgrade to Pro for unlimited processing with a one-time payment from $29 — no subscription.
Do the features work without an internet connection?
Completely. Once installed, 1FileTool needs no internet. Convert, compress, edit and batch-process files on a plane or behind a firewall — your documents, photos and videos never leave your device.
Which file formats does 1FileTool support?
100+ formats across PDF, images (JPG, PNG, WebP, SVG, HEIC), video (MP4, MOV, AVI, MKV), audio (MP3, WAV, FLAC, AAC), and data files (CSV, XLSX, JSON, XML, Markdown) — plus archives like ZIP.
