Compress PDF Online

An upload form rejects a PDF that opens perfectly on your computer. Making the file smaller helps only if the recipient can still read the small print, signatures and tables. Start with a moderate setting, check the result, and use stronger compression only when the upload limit requires it.

How can I reduce a PDF for an email or a 1 MB upload limit?

Lower quality or DPI can blur small text. Searchable text and interactive fields are lost; the requested file size is approximate.

Before you start

Keep the original file. Work on an exported copy, especially with signed forms or important documents. Check that the file opens and that the pages you need are present. A password-protected PDF may ask for its existing password; that password is not stored.

Check the exported result

Open the downloaded file before sharing it. Check the page count, order, orientation and any small text. Look at the first and last pages as well as the page you edited. For an upload limit, check the actual saved file size rather than relying only on an estimate.

Scans, text and signatures

A scanned PDF is a collection of page images even when it looks like a normal document. Image conversion does not automatically recognize text. Search-based redaction needs selectable text; scan images require manual boxes. Editing a document may invalidate existing digital signatures.

Local processing and shared devices

Files, text, edits and results are processed on your device and kept only in the open page. They are not uploaded for processing. Reloading or closing the page clears the workspace. Files you download to your device remain there until you delete them.
