Why CompressAndGo Wins on Privacy
Most popular compression tools share one fundamental issue: they require you to upload your files to their servers. Your documents, photos, and PDFs are transmitted over the internet and temporarily stored on external infrastructure you don't control. CompressAndGo is architecturally different — the entire compression engine runs inside your browser as JavaScript. Your files are processed by your own device's CPU and never leave your local environment.
Full Video Compression — Still 100% Private
No other free browser-based tool in this comparison offers true video compression. CompressAndGo uses FFmpeg compiled to WebAssembly, running entirely on your device. MP4, MOV, MKV, WebM, AVI and more — all compressed without a single byte leaving your browser.
In-Browser Image Resizing with Social Presets
The Resize Image tab lets you resize any image to exact pixel dimensions or pick from common presets — Instagram Post, Instagram Story, LinkedIn Banner, Pinterest Pin, Profile Picture, and more. After resizing, hit "Compress further" to reduce the file size too — all without any upload.
Why the Target KB Feature Matters
Most compression tools give you vague quality sliders or percentage estimates. CompressAndGo lets you specify exactly how large the output file should be — down to the kilobyte. Critical when uploading to portals with strict file size limits, sending via email, or optimizing for a specific platform.
PDF to Markdown — Browser-Native WebAssembly
CompressAndGo includes PDF to Markdown conversion powered by pdf-oxide-wasm — a Rust-compiled WebAssembly engine running entirely in your browser. Upload a PDF and get back a clean .md file plus all extracted images, packaged as a ZIP. No server, no account, no data transmitted.
Send Anywhere After Compression
After compressing, send your file directly to Gmail, Google Drive, Dropbox, OneDrive, WhatsApp, Discord, or any destination via your device's native share sheet — all with one click.
