About TweakFiles

Our Mission

TweakFiles exists to make file processing simple, free, and private. Every tool runs entirely in your browser — your files never touch a server.

How It Works

Traditional online file tools upload your documents to remote servers for processing. TweakFiles takes a different approach: we use modern browser APIs like the Canvas API, pdf-lib, and PDF.js to process everything client-side. This means:

• Complete privacy — files never leave your device
• Instant results — no upload/download wait times
• Works offline — once loaded, tools work without internet
• No limits — no file size caps or daily quotas

What We Offer

TweakFiles includes 14 specialized tools for PDF and image processing, plus 60+ image format conversion pages. From compressing PDFs by up to 90% to converting HEIC photos to JPG, every tool is free and unlimited.

Available Languages

TweakFiles is available in English, Spanish, Portuguese, German, French, Hebrew, and Russian — making our tools accessible worldwide.
