About this tool

Shrink a bulky PDF down to a far smaller file without sacrificing the quality that matters. The optimizer works on images, fonts, and embedded content, applying smart compression that trims size while keeping pages visually clear: text stays sharp and searchable, and graphics are reduced to the smallest sensible footprint. That lets you slim down scanned documents, image-heavy decks, or long reports so they fit under email attachment caps, upload faster to web portals, and take up less room in storage. Confidentiality is never a trade-off here, because every byte is processed locally in your browser and not a single file is sent to any server, so even sensitive material stays private and on your device. When optimization completes, the polished, high-quality PDF is ready to download immediately. It's a reliable choice for professionals battling attachment limits, students meeting strict submission sizes, and anyone who simply wants a lighter, easier-to-share PDF.

Frequently Asked Questions

Savings depend on the file's contents and the quality level you pick. The tool restructures the PDF using object streams and can strip metadata, which trims overhead. Image-heavy and bloated documents typically benefit the most.
Text stays sharp and searchable because it isn't rasterized. You choose a quality level from low to high to balance file size against fidelity, so you can favor smaller files or preserve more detail depending on the document.
Yes. There's an option to strip out metadata such as title, author, and keywords, which both reduces size slightly and removes hidden personal details. It's useful before sharing a document you'd rather not have tagged with your info.
There's no fixed server-side cap because compression runs locally in your browser. The practical limit depends on your device's available memory, so very large files work but may take longer on lower-powered machines.
Completely. No files are uploaded to any server; all optimization happens on your own device. That makes it safe for compressing confidential reports or contracts that you need to email or archive without exposing them online.
