Compress PDF
Shrink the file by choosing the balance between size and quality.
PDF too big to attach to an email or send on WhatsApp? Pick a compression level — light, medium or strong — and see how much it shrank before downloading. It is especially effective on photo-heavy PDFs and scanned documents, which are usually the heaviest ones.
Worth knowing how it works: to actually shrink the file, every page is rewritten as an image. The PDF still opens and prints normally, but the text is no longer selectable or searchable — that is why we show the result before the download, so you can decide. If you need selectable text, use the light level or keep the original.
Every other PDF compressor uploads your document to a server. Not here: a contract, a report or a payslip is processed inside your browser and never leaves your device.

Frequently asked questions
How much smaller does it get?
It depends on the content. Photo PDFs and scanned documents usually drop 50% to 90%; an already optimized text-only PDF may not shrink at all — in that case we tell you there was no gain and you keep the original.
Is the text still selectable afterwards?
No. Since every page becomes an image, the text is no longer selectable or searchable. That is the price of a big reduction — if that matters, use the light level or keep the original file.
Does it work with password-protected PDFs?
No. Remove the protection from the file before compressing.
Is my document uploaded to a server?
No. The PDF is opened, recompressed and saved inside your browser — nothing is sent, which matters when the document has personal data.
