273 File Tools. Everything Processed Locally.
1FileTool brings 273 tools for PDFs, images, video, audio, text, and more into one app — with every operation running entirely on your device. No uploads, no subscriptions.
Every time you compress a PDF, convert an image, or rename a batch of files, you're making a choice: send the file to an online tool and hope it's not stored, or string together three different apps to do what you need. Most online file tools process your files on their servers. Most desktop tools either do one thing well or do everything badly.
1FileTool takes a different position. Every tool runs on your device. Nothing goes to a server. And instead of picking between a focused app and a Swiss-army-knife web tool, you get 273 tools in a single app — with a clean interface that doesn't get in the way.
One App for Every File Type
You no longer have to maintain a mental map of "which tool do I use for this?" 1FileTool covers PDFs, images, videos, audio, text, code, archives, and more — with tools that go deep enough to handle real workflows, not just the most common one.
The entire app works offline. Drop a file in, get a result out. Nothing leaves your device.
How It Works in Practice
PDF tools that cover the full document lifecycle
The PDF section has 39 tools covering the entire workflow: merge multiple PDFs, split one into chapters, compress for email, add watermarks, password-protect, fill forms, extract text, run OCR on scanned documents, and repair corrupted files. The tools that developers often need — extract images, set permissions, convert to PDF/A for archival — are there too, not hidden behind a "Pro" upsell.
Image tools for every format and editing need
37 image tools handle compression, resizing, format conversion (JPG, PNG, WebP, HEIC, GIF, BMP, TIFF, ICO), cropping, rotation, color adjustment, batch watermarking, EXIF stripping, and image generation for common web assets like favicons, Open Graph images, and social media sizes. Convert a folder of HEIC files to JPG without writing a script. Strip GPS data from images before sharing them.
Video and audio without the command-line overhead
ffmpeg is powerful, but looking up the right flags every time isn't. The video section wraps the most common video workflows — compress, convert format, trim, merge, extract audio, add subtitles, change speed — into a drop-and-configure UI. Audio tools cover the same ground for standalone audio files: convert, trim, normalize loudness, remove silence.
85 Power Tools for text and data
The Power Tools section is where the depth shows: normalize Unicode, mask emails and credit card numbers in documents, extract all URLs from a text file, slugify strings, validate and pretty-print JSON, generate HMACs, detect language and character encoding, compute Levenshtein distance. These are tools that developers and power users reach for occasionally but always want available.
The Command Palette and History
Press Cmd+K to search across all 273 tools from anywhere in the app. The processing history keeps a log of every file you've processed with the tool used, date, and file size — so you can reprocess something weeks later without remembering how you did it the first time.
Before vs After
| Task | Before | After |
|---|---|---|
| Compress a PDF | Upload to Smallpdf or similar (file leaves your device) | Drop into 1FileTool PDF Compress → local, instant |
| Convert HEIC to JPG for batch of photos | Install ImageMagick, write a script, or use a web tool | Batch convert in Image Tools |
| Strip EXIF from images before sharing | Separate app or command-line tool | Privacy Tools → Strip EXIF |
| Rename 50 files with a pattern | Write a script or use a specialized renamer app | File Tools → Batch Rename with live preview |
| Find duplicate files eating disk space | Third-party app | File Tools → Find Duplicates |
Who Benefits Most
Developers and power users who value data privacy — Your client's PDF, your API response, your source files — none of it needs to leave your machine to be processed. 1FileTool is the answer to "I need a tool but I don't want to upload this."
Anyone who maintains a file processing toolkit — Instead of bookmarking five online tools and hoping they still work next month, you have 273 in one app, offline, with no subscription.
Teams handling sensitive documents — Legal, finance, HR — anyone working with files they can't upload to a third-party server now has a full-featured processing toolkit that works entirely locally.
