Step 1
Upload Your PDF
Drag and drop a PDF file into the PDF Compressor, or click to browse your device and select the exact document you want to shrink before moving on to the compression settings screen and choosing a level that fits.
Step 2
Pick a Compression Level
Choose Low, Medium, High, or Custom compression depending on how much you want to shrink the file and how much visual quality you need to keep intact for sharing, printing, emailing, or archiving important documents later on.

Frequently Asked Questions
A PDF Compressor analyzes a PDF and rebuilds it at a smaller file size, so it is faster to upload, easier to email, and takes up less storage space, all while keeping the layout, fonts, and text readable on any device or app you use daily for work.
This PDF Compressor offers four options: Low, Medium, High, and Custom, so you can match the compression strength to the specific file you are working with and how much visual quality you want to preserve afterward for sharing, printing, or archiving documents at work.
Yes. Selecting Custom unlocks a quality slider from 0 to 100 percent, letting you fine-tune the balance between a smaller file size and sharper visual quality before you actually compress the document and download the final, noticeably smaller result to keep.
Yes, the tool displays the original file size, the compressed file size, and the percentage reduction side by side right after processing, so you can confirm the result before you commit to downloading the smaller file to your device or sharing it with others.
The PDF Compressor is built to keep documents readable at every level, but higher compression settings can soften image sharpness, especially in files that are heavy on photos, scans, or detailed graphics, charts, and screenshots taken from other apps or tools.
No. The PDF Compressor runs entirely online in your browser, so there is nothing to download, install, or configure on your computer or phone before you start compressing your PDF files today, right from any browser tab or window you already have open right now.
Behind the scenes it tests multiple compression strategies on your document and automatically keeps whichever result is smallest, so the compressed PDF you download is never larger than the original file you uploaded to the tool in the first place, which is a genuine, reliable guarantee.
