Frequently asked questions
Yes. Compress PDF is available on the free plan. Free accounts have a limit of 2 operations per hour and 5 MB per file. Pro removes the hourly cap and raises the file size limit to 500 MB.
All uploads go over HTTPS. Snappdf processes the file, returns the result, and deletes both the upload and the output from our servers within one hour. We do not read, share, or sell your file contents.
Free accounts can upload files up to 5 MB. Pro accounts handle files up to 500 MB. In batch jobs, each file is subject to these limits individually.
No. Snappdf runs entirely in your browser; there is nothing to download or install. The optional Chrome extension adds one-click access to PDFs you encounter on the web.
