How it works

Compress a large PDF in 3 easy steps

1
Upload your PDF

Choose the PDF file you want to shrink. No account or software needed.

2
Choose a compression level

Pick Maximum Compression, Recommended, High Quality, or set your own target size.

3
Download the smaller file

Your compressed PDF is ready in seconds — download it straight to your device.

Large PDF documents can take longer to upload, consume more storage space, and may exceed a website’s file-size limits. Here you can reduce the PDF file size according to your needs — for example, if an application portal accepts files up to 1MB, use the target-size option to compress your PDF to 1MB.

Compression options

Pick the level that fits your file

Maximum Compression

Shrinks the file as much as possible. Best when file size matters more than image sharpness — for example, email attachments or upload limits.

Recommended

A balanced setting that noticeably reduces size while keeping the document easy to read. Good default for most PDFs.

High Quality

Reduces size with minimal change to image and text quality. Best for documents you plan to print or share professionally.

Custom Target Size

Tell it the exact size you need (like 1MB or 2MB) and it compresses to fit that target.

Questions

Frequently asked questions

Is Free PDF Compress really free?

Yes. There’s no subscription, no payment, and no sign-up required to compress your PDF files.

Will compressing reduce my PDF’s quality?

Some compression levels reduce image quality slightly to save more space. If quality matters most, choose “High Quality” or set a custom target size closer to your original file size.

What happens to my file after I upload it?

Your file is uploaded to our server, compressed using Ghostscript, and automatically deleted once processing is complete. We don’t keep copies of your documents.

Do I need to install any software?

No. Free PDF Compress works entirely in your browser — there’s nothing to download or install.

What’s the difference between the compression levels?

Maximum Compression prioritizes the smallest file size, Recommended balances size and quality, High Quality keeps output close to the original, and Custom Target Size lets you specify an exact size to aim for.
