Optimize PDF

Optimize PDF for web, print or archive — remove duplicates and compress.

Use Cases

Typical scenarios for Optimize PDF — see if it fits before you start

Optimize PDF · Scenario 1

Email caps 2–10MB. Optimize PDF compresses via font subsetting/object dedup/resampling — e.g., 8MB to ~1.5MB while sharp.

Optimize PDF · Scenario 2

Archiving reports, Optimize PDF offers target 1/2/5/10MB with before/after comparison.

Optimize PDF · Scenario 3

Batch compressing bids, Optimize PDF queues with progress; one failure not blocking others.

How to Use

  1. Upload — Click or drag PDF/images to the dashed zone. Multi-file and large files (<100MB per batch recommended) are read locally only.
  2. Configure & process — Set pages, angle, password or quality, then hit “Calculate / Process”. Optimize PDF runs via WebAssembly and pdf-lib in your browser — no server queue.
  3. Preview & download — Check pages, size and thumbnails on the right, then download. Batch jobs download one by one; tweak and re-run if needed.

Tips & Notes

  • Page syntax: Use 1,3,5-7 or 1-10,15; empty means all. Out-of-range pages are ignored.
  • Privacy & size: Everything runs locally — no server upload. For large files, process in batches of 50–100 pages.
  • Fidelity: Fonts and vectors are preserved where possible. For scanned PDFs, run OCR/searchable PDF first, then convert.

Funktionen

  • Remove redundant objects
  • Image resampling
  • Size vs clarity balance

FAQ

Will files be uploaded? Is Optimize PDF safe?

No. Optimize PDF runs 100% in your browser via File API; no network upload, memory cleared when you close the tab.

Processing failed or download blocked?

Check page ranges, passwords and file integrity. If the browser blocks multiple downloads, allow “automatic downloads” or click links one by one.

How to chain with other compress tools?

Combine workflows: organize pages first, then compress/convert for submission, then protect/sign for delivery.
