PDF Compressor
Upload a PDF and choose a quality level; each page is re-encoded to reduce the overall file size.
Your files never leave your device — everything runs in your browser.
Compression:
Each page is redrawn as a compressed image, which works best for scanned documents and image-heavy PDFs. Text-based PDFs will lose selectable text after compression.
How to Use
- 1Choose a compression level (higher quality keeps more detail, lower quality shrinks more).
- 2Drop in your PDF file.
- 3Download the compressed PDF once processing finishes.
Frequently Asked Questions
Will the compressed PDF still have selectable text?
No — each page is converted into a compressed image, so text is no longer selectable or searchable. This trade-off is what makes the file smaller.
Is my PDF uploaded to a server?
No. Everything is processed locally in your browser using PDF.js and jsPDF; your file never leaves your device.
