Three simple steps
- Upload your PDF. Enter its password only if asked.
- Choose a KB preset or type the maximum size you need. Press Apply Resize.
- Check the output size and preview, then download.
Automatic quality adjustment
The tool first tries to keep original text and optimise embedded scan images. If the target needs stronger compression, it automatically tries image-based output at several resolutions. A very small target can reduce text and QR clarity. All pages remain in order; always check small details and scan QR codes before submitting. Some PDFs cannot reach every target.
Processing is local in your browser. PDF libraries need internet to load. Up to 30 MB and 10 pages per file; 1 KB means 1024 bytes. Rewritten PDFs may lose selectable text, links, forms, attachments, password protection and valid signatures. Keep your original file. Existing website advertising and analytics remain.
