Domande frequenti

How much smaller will my PDF be?

It depends on the content; image-heavy PDFs shrink the most. PDFs full of photos or scans can often shrink by 50% or more, while text-only files are usually small already.

Is there a file size limit for the PDF Compressor?

Yes, a limit applies to keep the service fast for everyone, and it is shown in the upload box. Most everyday documents fit easily. If a file is too large, compress it first or split it into smaller parts.

Will the PDF Compressor change the quality or layout of my document?

No. The tool keeps your text, fonts, images and page layout as close to the original as the source file allows. For the cleanest result, always start from the original digital file rather than a blurry scan.

Is the PDF Compressor safe and private?

Yes. Your files travel over a secure HTTPS connection, are used only to create your result and are deleted from our server automatically. You do not need an account, and the tool works the same way on phones, tablets and computers.

Is the PDF Compressor free to use?

Yes. The PDF Compressor on pdfseotools.com is free to use – no sign-up, no watermark and no hidden charges for everyday tasks.
