The problem with cloud tools
Online and cloud-based alternatives come with real trade-offs.
"Free" means uploaded and tracked
Most free online converters pay for themselves by uploading your files and harvesting data with trackers and ads. Free in price, costly in privacy.
Caps, queues and watermarks
Free web tiers limit file size, make you wait in a queue, and slap watermarks or daily caps on the output to push you toward a subscription.
A different site for every format
You bounce between sketchy single-purpose websites — one for HEIC, one for PDF, one for video — each with its own ads and upload prompt.

Frequently asked questions
Is 1FileTool really free?
Yes. All 265+ tools are free to use for up to 8 files per day, with no account and no credit card. When you need unlimited processing, Pro is a one-time purchase from $29 — never a subscription.
What is the catch with a free converter that does not upload?
There is no catch. Because everything runs on your own machine, there are no server costs to recover, so 1FileTool does not need to harvest your data, show ads, or watermark your files like typical free web converters do.
What file types can I convert for free?
You can convert PDFs, images (HEIC, PNG, JPG, WebP and more), videos (MP4, MOV, AVI, MKV), audio (MP3, WAV, FLAC, AAC) and data files (CSV, Excel, JSON, XML) — all offline.
Do I need to create an account or be online?
Neither. There is no sign-up, and after installing the app it works completely offline. Your files never leave your device.
Does it work on Mac and Windows?
Yes. 1FileTool is a native app for macOS (Apple Silicon and Intel) and Windows, with the full set of 265+ tools on both.
