Document tool
Compress PDF
Shrink a PDF in your browser with simple presets inspired by dedicated PDF utility suites, then download the smaller file in one step.
Choose one PDF to compress. This version keeps the workflow focused instead of bundling every PDF action into one screen.
Drop your PDF here
PDF.js reads the pages, then jsPDF rebuilds a smaller document using the compression preset you choose.
Best for
Good balance for most scanned PDFs.
Expected change
Medium compression
Balanced uses moderate page scaling and JPEG quality, which usually works well for reports, scans, and mixed documents.

What this tool does
This first document utility focuses on one job only: reducing PDF file size. You upload a PDF, choose a compression strength, and export a smaller copy without dealing with a larger toolkit screen.
How compression works here
The page uses PDF.js to read and render each page, then rebuilds the document with jsPDF using compressed page images. This approach is especially helpful for scanned, image-heavy PDFs.
What to keep in mind
Because the compressed file is rebuilt from rendered pages, selectable text, links, and form fields may be flattened. For text-heavy PDFs, the size reduction may be modest compared with scanned files.

How it works
How compression is handled
- • Upload one PDF by clicking the picker or dropping the file into the upload area.
- • The tool reads the document in your browser, counts pages, and renders a preview of the first page.
- • Choose a preset to control render scale and JPEG quality for the rebuilt PDF.
- • The compressor rebuilds the pages into a new PDF and shows the output size before download.
FAQs
Common questions
FAQs
Common questions
Does this work well for scanned PDFs?
Yes. Scanned PDFs and image-heavy files usually benefit the most from this style of compression because each page image can be reduced in resolution and quality.
Will text stay selectable?
Not always. This compressor rebuilds pages from rendered images, so text, form fields, and embedded links can become flattened in the output.
Are my files uploaded to a server?
No. The processing happens in the browser on your device, so the PDF stays local during compression.
