How to compress a PDF

  1. Drop one or many PDFs into the tool below. Big files are fine — they never leave your device.
  2. Choose a compression level — light, medium or maximum. Higher compression = smaller file but slightly softer images.
  3. Optionally set an image-quality target. Text stays sharp either way.
  4. Click Run. Download each compressed PDF or grab them all as a ZIP.

Frequently asked questions

Are my PDFs uploaded anywhere?

No. Every PDF is processed locally inside your browser. Nothing is sent to a server. This tool works with your wifi turned off. That makes it POPIA-safe by default: no third-party processing of personal or client data.

How much smaller will my PDF get?

It depends on what is inside. A scan-heavy PDF can drop 60-80% at medium compression. A text-only PDF (already efficient) may only drop 5-15%. Try each level and use the smallest that still looks right.

Is there a file size or batch limit?

No hard limit. Drop as many PDFs as you like - the only real constraint is your device memory. Because everything runs in your browser, huge batches are fine on a decent laptop.

Do you offer a paid version or account?

No - free forever, no accounts, no email required, no watermarks. Ikonik Studio built these tools as a free service. If you need custom development, that is a different conversation.

Need a full website, not just a tool?

Ikonik Studio is a Johannesburg digital studio building websites, brand systems, ecommerce and marketing for South African clients. These free tools are a side project — the main work is client builds.
