Reduce your PDF file size in your browser — no upload, no size limit.
Compression shrinks the file size of a PDF so it's easier to email, upload or store. Nearly all the weight in a scan or an export is its embedded photos, so that is what this re-encodes — text, vectors, links and form fields are written back untouched. It all runs in your browser, which means a 50 MB scan is no harder than a small one and the document never leaves your device.
No. Compression runs in your browser, so the PDF never leaves your device — there is no server to send it to and nothing to delete afterwards.
Only your device's memory limits it. A 50 MB scan is fine on a normal laptop or phone, because your browser is doing the work instead of an upload.
Yes — text is stored as vectors and is never re-encoded. Only the embedded photos are, so at the highest setting you may see softness in images and none in the type.
Because it had no photos to shrink — a text or vector document is already close to its smallest size. When re-encoding would not help, the original file is handed back rather than a larger copy of it.
It's free, private and works right in your browser — no signup, no watermark.
