About this tool

Shrink PDF file size when email limits or storage matter. Choose light cleanup of metadata and structure, or strong mode that rasterizes pages to JPEG for scanned documents.

Why use it

  • Light mode re-saves without heavy metadata — quick and lossless for text PDFs.
  • Strong mode cuts size on image-heavy or scanned PDFs.
  • Everything runs locally; confidential PDFs stay private.

Common use cases

  • Email a report that exceeds the attachment limit.
  • Archive scanned invoices with smaller files.
  • Strip author metadata before sharing externally.

Tips

  • Try light mode first on text PDFs — it is fast and non-destructive.
  • Use strong mode only when you accept that text may become non-selectable.
How to use
  1. Upload a PDF.
  2. Pick light or strong compression.
  3. Download the smaller file.
FAQ
How does PDF compression work here?
Light mode re-saves and strips metadata. Strong mode rasterizes each page to JPEG for smaller scans.
Is my PDF uploaded?
No. Compression runs entirely in your browser.
Will text stay selectable?
In light mode yes. Strong raster mode turns pages into images, so text may not be selectable.
How much smaller will my file get?
It depends on the original. Scanned PDFs often shrink the most in strong mode.
Are password-protected PDFs supported?
Encrypted PDFs may fail to load unless you unlock them first elsewhere.
Which mode should I pick?
Try light first for text PDFs; use strong for large scanned documents.
