Compress your PDF and reduce its size, free
With this tool you can compress a PDF and reduce its weight to send it by email, upload it to a website or save space. It works especially well with scanned documents or documents with many images, which tend to be the heaviest.
The process optimizes each page by rasterizing it to an image and rebuilding the document, and everything happens in your own browser: there is no watermark, you do not need to sign up and your files are never uploaded to the internet, which makes it fast and completely private.
Free, no watermark
No usage limits and no stamped files. The result is 100% yours.
Private by design
Everything is processed in your browser. Your documents are never uploaded.
Fast
No queues, no waiting: it uses the power of your own device.
No sign-up
No account and no email needed. Just open it and start working.
Frequently asked questions
How does this tool reduce the PDF size?
It converts each page into an optimized JPEG image and rebuilds the PDF with those images. That is why it works especially well with scanned documents or documents with many images.
Will the text still be selectable?
No. When the pages are rasterized to images, the text can no longer be selected or copied. If you need to keep the text selectable, this is not the right tool.
Are my files uploaded to the internet?
No. All compression happens inside your browser. Your PDF is never sent to any server.
Is the size always reduced?
For most scanned or image-heavy PDFs, yes, and quite a lot. For PDFs that are already very light or text-only, the reduction can be small or even none.
