Reduce the size of scanned and picture-heavy PDFs so they fit email and upload limits. Boltly tells you honestly when a PDF has nothing left to shrink.

  2. Choose how strong the compression should be.
  3. Press Compress and save the smaller PDF.

Private by design

Boltly runs entirely in your browser. Your files are processed on your own computer and are never uploaded, so it is safe for IDs, contracts and family photos, and it keeps working offline once loaded.

Questions

Why did my PDF barely shrink?

Text-only PDFs are already small; the savings come from pictures and scans inside the PDF.

Is my PDF uploaded?

No. It is processed in your browser.
