Is DocTools Pro really free?

Yes. Every tool is free to use, with no account, subscription or usage cap.

Are my files uploaded anywhere?

No. Processing happens locally in your browser, so files stay on your device and are never transmitted to a server.

Do I need to install anything?

No installation is needed. It runs in modern browsers such as Chrome, Firefox, Edge and Safari.

Does it work on mobile devices?

Most tools work on phones and tablets, though large files are easier to handle on a desktop or laptop.

Do I need internet access to use the tools?

You need a connection for the initial page load, but most tools keep working afterwards even if your connection drops.

Will my files be deleted automatically?

There is nothing to delete — files are never sent to a server, so nothing is stored on the provider's side in the first place.

Password-protect documents, images, audio, video and archives, and decrypt them again entirely inside the browser.

100% local, private processing

Everything executes locally in browser memory, so files never leave the device, there is no size limit on conversions and closing the tab clears the session.

DocTools Pro is a free, browser-based toolkit for everyday document and image jobs: merging and splitting PDFs, converting between 20+ formats, compressing files, running OCR, removing image backgrounds and password-protecting anything. It is built in Switzerland and designed around local processing — files are handled in your browser's memory and never uploaded to a server, so there is no account, no file-size cap and nothing stored on the provider's side.

DocTools Pro の効果的なユースケース

Office and admin worker

Everyday PDF wrangling

Merge a stack of invoices into one PDF, split a long report into sections, or compress a file so it fits in an email attachment — all without sending anything to a remote server.

Designer / marketer

Image prep and conversion

Convert HEIC photos to JPG, resize and compress images for the web, or strip backgrounds, keeping client assets entirely on the local machine.

Privacy-conscious professional

Encrypt sensitive files

Password-protect contracts, statements or archives and decrypt them later in the browser, so confidential files never touch third-party infrastructure.

Student / researcher

Offline document conversion

OCR scanned documents into searchable text and convert spreadsheets between CSV, XLSX, ODS and XLS without uploading business data anywhere.

Regulated industry staff

Compliance-friendly processing

Handles data in industries where uploading to third-party servers is not permitted, since all processing stays client-side.
