Frequently asked questions
Can any PDF reach 100KB?
It depends on what's inside. Text-only documents compress to tiny sizes easily, while PDFs full of high-resolution photos or scans may not reach 100 KB without a visible drop in image quality.
Is this free?
The core PDF tools on PDFGrove are free; this one is part of Pro, which also raises file-size limits and removes daily caps.
Are my files kept private?
Yes. Files are sent over an encrypted (HTTPS) connection and deleted from the server automatically a short time after processing.
Do I need to install anything?
No. PDFGrove runs entirely in your web browser — there's nothing to download or install.
Does it work on mobile?
Yes. It works in any modern browser on phones, tablets, and computers.
What file size can I use?
Free users can process files up to 10 MB; Pro raises the limit to 200 MB.
