Common questions

Is Compress PDF free?

Yes — Compress PDF is free with no sign-up, no watermark and no daily limit on this tool. Heavier operations (OCR, conversion) have a generous daily quota on the free plan and are unlimited on Pro.

How do I compress pdf?

Open Compress PDF, drop your file, set the options, and download the result in a few seconds — processed securely, no queue and no ads.

Are my files safe?

Files are sent over an encrypted connection and deleted automatically after processing. No one else can access them and they are never used for anything but your task.

Will compressing make the PDF look worse?

Most of the saving comes from images, so a text-heavy document compresses a lot with no visible change, while a photo-heavy one trades some image detail for size. Text stays sharp and selectable either way.

Why did my PDF barely get smaller?

It was probably already optimised, or it is mostly text — there is little left to squeeze. Scans and image-heavy files shrink the most.
