What you can do with Compress PDF

Compressing rewrites a PDF so it takes up less space — mainly by optimising embedded images and stripping redundant data — making the file easier to email, upload, or store.

Get under an email limit

Shrink a photo-heavy PDF so it fits within a 10 MB or 25 MB attachment cap.

Speed up a web upload

Reduce a large scan before submitting it to a government portal, job application, or loan form that rejects big files.

Save storage space

Compress archived documents so a folder of scans takes a fraction of the disk or cloud space.

Share faster

Send a lighter file that downloads quickly for recipients on slow or mobile connections.

Why Compress PDF runs great in Chrome

Chrome's V8 JavaScript engine and its strong WebAssembly support are exactly what a browser-based PDF tool needs. ContinuePDF leans on both to compress your PDF at near-native speed inside the tab — no extension required, because everything the tool needs is already part of the page.

Avoiding an extension matters for more than convenience. Extensions request permissions, can slow the browser down, and are one more thing to keep updated and trust. ContinuePDF asks for none of that: open the page in Chrome, compress your file locally, and download compressed PDF. Your document is processed on your device and never uploaded.

Pro tip

Most of a PDF's size usually comes from scanned pages and embedded photos, not text. If a file is still too big after compressing, check whether it is a scan — reducing image resolution has the biggest effect, while a text-only PDF is already small.

Frequently asked questions

Will compressing make my PDF look worse?

At a moderate level, text and vector graphics stay sharp and the savings come from optimising images, so documents still look clean. The strongest setting works harder — it can even convert pages to images to shrink the file further, which softens photos and makes text non-selectable — so choose a moderate level when you need to keep text crisp and selectable.

Why didn't my PDF get much smaller?

If the file is mostly selectable text, it is already efficient and there is little to remove. The biggest savings come from PDFs built around high-resolution images or scans.

Do I need a Chrome extension to compress PDFs?

No. Compress PDF works as a regular web page in Chrome — there is no extension to install. Just open the tool, add your PDF, and download compressed PDF.

Is Compress PDF fast in Chrome?

Yes. It uses Chrome's V8 JavaScript engine and WebAssembly to process your PDF at near-native speed right in the tab, so most jobs finish in seconds.

Is ContinuePDF free to use?
