Shrink PDFs with pikepdf optimize_streams to hit inbox and portal limits without losing fidelity.

Compress PDF: Meet every upload limit

Large decks, scan-heavy proposals, or bill-of-materials PDFs can stall in email or procurement portals. Compress PDF in Tools & News uses pikepdf under the hood to optimize streams, clean up redundant objects, and produce a professional document that still looks sharp.

Why users love it

  • Deterministic results: the same file + settings yields the same output—ideal for regulated workflows.
  • Local-only processing: nothing leaves your droplet, so sensitive financial or legal docs stay internal.
  • Instant download: no queues or email links; just click Compress and grab the lighter file.
  • Pairs well with PDF Merge/Split for more complex document prep.

Steps

  1. Open /tool/compress-pdf.
  2. Upload a PDF up to 100 MB.
  3. Hit Compress PDF; the backend optimizes using pikepdf.
  4. Download and share the reduced file.

Best practices

  • Run this tool before uploading to e-sign portals or government sites with strict caps.
  • Combine with PDF Merge to keep multi-file packets tidy before compressing.
  • Keep originals backed up so you can revisit full-resolution copies later.

FAQ

How much smaller will my file get?
It depends on the content—image-heavy documents shrink the most.

Is there quality loss?
Streams are optimized but not rasterized, so text and vector art remain crisp.

Can I batch multiple PDFs?
Compress them one at a time, or merge first, then compress the combined file.

What about encrypted PDFs?
Provide unprotected files; password-locked documents aren’t supported yet.
