About the Compress PDF
Large PDFs bounce back from email, fail on job and exam portals and take forever on WhatsApp. This compressor shrinks the images inside your PDF while keeping text, links and layout intact. For scanned documents, the Extreme mode re-renders every page as an optimized image for the smallest possible file — and you can even set a target size like 200 KB.
How to use the Compress PDF
- Add one or more PDF files.

Frequently asked questions
How much can a PDF be compressed?
Image-heavy and scanned PDFs often shrink by 50–90%. PDFs that contain only text are usually already small, so savings are lower.
Will the text stay selectable?
Yes in Low and Recommended modes — only images are recompressed. Extreme mode turns each page into an image, so text is no longer selectable.
Can I compress a PDF to 100 KB or 200 KB?
Yes. Pick Extreme mode and enter a target size; the tool automatically lowers quality until the file fits.
Is my PDF uploaded to a server?
No. Compression happens entirely in your browser, so confidential documents stay on your device.
Is the Compress PDF free?
Yes. Compress PDF on Tooliphy is 100% free with no signup, no watermark and no usage limits.
Is it safe to use? Are my files uploaded?
Your data is processed directly in your browser and is never uploaded to our servers, so it stays completely private.
Does it work on mobile?
Yes, the tool works on Android phones, iPhones, tablets and desktops in any modern browser.
