Drop in a PDF and compression starts automatically. Everything happens in your browser, so your file never leaves your device.
CompressIt is a free online PDF compressor designed to reduce PDF file size directly in your browser. Your document stays on your device while it is being compressed — no upload, account or file storage required.
CompressIt processes documents entirely in your browser. Your PDF is not uploaded to or stored on a CompressIt server.
CompressIt uses Google Analytics to understand general website traffic and usage. Analytics may collect technical information such as device type, browser, approximate location and interactions with the website. Analytics never receives the contents of your PDF documents.
Third-party content delivery services used for fonts and JavaScript may receive standard technical data such as your IP address and browser type.
CompressIt is provided free of charge and on an “as is” basis. Keep your original PDF and check every compressed result before relying on it.
Compression rebuilds each page as an image. Selectable text, hyperlinks, forms, bookmarks and accessibility tags may not be preserved.
Do not use the service for unlawful material or documents you are not authorised to process.
Questions, suggestions and bug reports are welcome.
