Compress PDF

About the Compress PDF

Compress PDF re-saves your document with optimised image quality and streamlined fonts to cut its size dramatically — often by 60-80% for scanned material. Perfect for email attachments that hit size limits, or for speeding up downloads on the web.

How to use

1. Drop the PDF you want to shrink into the upload area.
2. Pick a compression level (Recommended balances size and clarity).
3. Download the smaller PDF once the counter shows Done.

Benefits & key features

• Slim PDFs load faster and sail through strict attachment-size caps.
• Multiple quality presets let you choose between smallest file and best visuals.
• Text remains sharp and selectable — we don't flatten to image.
• Great for portfolios, e-mail newsletters, government form submissions and mobile viewing.

Pro tip

Heavily scanned PDFs compress the most. If your file was exported directly from Word or InDesign, gains will usually be smaller — consider using Compress Image on the embedded images first.

Why choose toolsfy for PDF tools?

Cloud-based PDF editors ask you to upload sensitive invoices, contracts or passport scans to servers you will never see — and then offer a "premium" plan to remove watermarks they added themselves. toolsfy turns that model upside down: every PDF operation on this page runs locally in your browser using the same modern Web APIs Chrome, Edge and Firefox ship with. Your file never leaves the device, no account is required, and there is no artificial cap on pages or size.

Common use cases

• Lawyers and accountants cleaning up scanned bundles of evidence before a client meeting, without sending them through a third-party server.
• University students assembling a single submission-ready PDF from multiple chapters, diagrams and reference pages — on a laptop with flaky campus Wi-Fi.
• Small-business owners stripping metadata, rotating scans, or watermarking product manuals before sharing them publicly on their website.
