Compress PDF

Reduce PDF file size without losing quality — optimal for email and web.

Use Cases

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

Recruiting portals often cap at 2MB. Compress from 5MB to ~1.5MB while keeping text sharp.

Meet 10MB limits by removing redundant objects and optimizing images without font loss.

Shrink annual reports 40-60% for cloud storage while preserving vector quality.

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

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.

Will files be uploaded? Is Compress PDF safe?

No. Compress 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.

Upload PDF, choose compression level, compress and download.
