Will I notice a quality difference?

Re-encoding always costs something, so start at the lighter setting and only push further if the size is still wrong. The before-and-after figures on the page are the honest way to decide.

Do I need to pay or register?

No. Every tool on this site is free, with no account, no email and nothing to install.

Which file types does Low Compression PDF accept?

The drop area takes PDF. Files are read from your device in the browser, so the format has to be one a browser can decode — that is why the accepted list on this page is finite and honest rather than "everything".

What do I get back from Low Compression PDF?

The result is PDF, offered as a download the moment the work finishes. Multiple results come back together rather than as fifty separate save dialogs.

About Low Compression PDF

The job of Low Compression PDF is narrow on purpose: light compression that keeps the highest visual quality. It takes PDF and produces PDF. Files up to 100 MB each, 50 at a time, and the work happens on your own machine rather than on a server.

Reach for it when making a document lighter without wrecking it is a one-off rather than a workflow: one file, one result, no account in front of it.

How to use Low Compression PDF in 3 steps

Drop the file on the page — PDF, one file up to 100 MB.
Set Compression strength — low, recommended, extreme, or custom, which then exposes Render resolution and JPEG quality.
Press Compress PDF and download the PDF result.

What you get with Low Compression PDF
