Frequently Asked Questions(FAQ)

Why compress PDFs?

Compressed PDFs upload faster, save storage, and are easier to share by email or messaging apps. Ideal for students, businesses and anyone who needs to send documents without slowing down recipients.
What does compressing a PDF do?

It reduces file size by optimizing images, removing redundant data and recompressing embedded images while keeping the document readable.
Will compressing change the PDF quality?

We offer multiple compression levels. Low compression keeps quality, Medium balances size and quality, and High reduces size the most with some quality loss.
How long are my files stored?

All files are automatically deleted from our servers after one hour. We do not keep a permanent copy.
What file size is supported?

Uploads up to 250 MB are supported. For larger files consider splitting the PDF locally before compressing.
