What is 1FileTool?
1FileTool is an offline file converter for Mac, Windows and Linux: 270+ PDF, image, video, audio and privacy tools that run on your own computer.
1FileTool is an offline file converter for the desktop: more than 270 tools for PDFs, images, video, audio, files, text, design and privacy, all running on your own Mac, Windows PC or Linux machine. Drop a file — or a whole folder — and the work happens locally, with no uploads and no account to create.
What you can do with it
- PDFs: compress, merge, split, reorder, convert to and from Word or images, protect, redact and OCR scans — see Compress and PDF to Word.
- Images: convert (HEIC included in every image tool since v1.10.0), compress, resize, strip EXIF and remove backgrounds — see Convert.
- Video and audio: compress H.264, turn clips into GIFs, extract or normalize audio — see Video to GIF.
- Files and data: batch rename with patterns, convert CSV ↔ Excel ↔ JSON ↔ XML, find duplicates and build ZIP archives — see Rename by Pattern.
- Privacy: shred files, strip photo and PDF metadata, and detect or redact PII — see Strip Metadata.
- Editors and automation: a visual PDF editor, a Markdown editor, Workflow Recipes that chain tools, and a Folder Monitor that watches folders for you.
- AI, optionally: on-device Read Aloud, audiobooks, Voice Cleanup and Background Removal, plus AI Chat and MCP access for the coding assistants you already use.
Every tool works in batch: drop many files at once, watch the background task bar, and get a per-file result with its size before and after.
Free and Pro
The free tier covers every tool at 8 files per calendar day. Pro is a one-time payment — not a subscription — that removes the daily cap and unlocks a handful of extras like Auto-Redact PII and live smart-folder rules. Details: Free vs Pro.
An honest note about "offline"
Tools run locally, and your files are never uploaded for processing — that's the design. Two caveats worth knowing up front: a few AI features download a model the first time you use them, and anonymous usage analytics are on by default (you can decline or disable them). How processing works and Privacy: what leaves your computer spell out exactly what connects where.
Before your first run, read Where results go — the Replace source option that overwrites originals is on by default.
