Make a PDF smaller without a watermark

MyPDF compresses PDFs on the server with Ghostscript so you can pick a quality level. High quality keeps more detail. Extreme compression makes the smallest file.

The original and the result stay on the server only long enough for you to download them. We delete those files after 60 minutes and do not use them for ads or training.

Free accounts get 5 jobs a day. Pro and Team raise the file-size cap and the daily job pool. The same job is available from the API if you need it in a script.

Questions

Does compress upload my PDF?

Yes. Compress runs on the server. The original and the smaller file are deleted after 60 minutes and are not used for ads or training.

Will the PDF look the same?

High quality keeps more detail. Extreme compression makes the smallest file and can soften images. There is no watermark.

How much does compress cost?

5 jobs a day and files up to 25 MB are free. A $5 day pass is 100 jobs and 200 MB files for 24 hours. Pro is $9 a month or $69 a year.

Can I compress to 1 MB, 2 MB, or 5 MB?

Those are targets, not a guarantee. The same compress job has pages for 1 MB, 2 MB, 5 MB, email, and Gmail.
