File compressor · 100% private · No uploads

tinyfiles.

Compress PDFs and images entirely in your browser. Files never leave your device — there's no server, no upload, no data collection.

Features

Tiny by design.
Private by default.

Files are processed using WebAssembly in your browser tab. Nothing is ever uploaded to any server.

No upload wait. Processing happens locally at full CPU speed, so results are near-instant.

Compress up to 20 files at once and download them all in a single ZIP. Ideal for bulk workflows.

Adjustable quality slider lets you find the right balance between file size and visual fidelity.

Once the page loads, no network is required. Compress files anywhere — on a plane, in the field, anywhere.

Open the page and start compressing. No email, no sign-up, no payment. Just free and fast.

How it works

Drag and drop PDFs or images onto the page, or click to select. Up to 20 files at a time.

Choose a preset or use the slider to fine-tune compression. See the estimated size reduction in real time.

Download each file individually or grab them all in a ZIP. Your originals are untouched.
