Free PDF Compressor Online

The LegalTemplates PDF Compressor reduces the file size of your PDF documents directly in your browser. Upload any PDF up to 25 MB and download an optimized version that is smaller and easier to email, upload, or store. The compression engine tries multiple optimization profiles and returns the smallest result while keeping document quality intact. The entire process is free, requires no account, and your files are deleted from the server immediately after the compressed PDF is returned.

How our PDF compressor works

Intelligent Compression Profiles

The compressor runs your PDF through multiple optimization profiles and selects the one that produces the smallest file. This approach ensures you get the best possible size reduction without unnecessary quality loss for your specific document.

Preserve Document Quality

Text, vector graphics, and page layout remain sharp after compression. The optimizer focuses on reducing embedded image sizes, removing duplicate resources, compressing fonts, and subsetting unused characters to shrink the file without degrading readability.

Side-by-Side Size Comparison

After compression, the tool displays the original and compressed file sizes side by side so you can see exactly how much space was saved. If your file is already well-optimized, the compressor will let you know that it cannot be reduced further.

No Account Required

Upload your PDF and compress it immediately. There is no registration, no login, and no email required. The tool works on any device with a modern browser and processes files up to 25 MB.

When to compress a PDF

Large PDF files can be difficult to email, slow to upload to web portals, and expensive to store. Contracts with scanned signatures, leases with embedded images, and HR forms with company logos are common examples of documents that benefit from compression. The LegalTemplates PDF Compressor handles all of these cases and returns a smaller file that is ready to send, submit, or archive.

The compression process runs entirely on the server using a professional-grade optimization engine. Your file is uploaded, compressed, and returned as an immediate download. The original file and the compressed output are both deleted from the server as soon as the download completes. Nothing is stored or retained after you close the page.

Frequently asked questions

Is this PDF compressor free?
Yes. PDF compression is completely free. You can compress as many files as you need without creating an account or paying anything.
Will compression reduce the quality of my PDF?
The compressor uses intelligent profiles that prioritize document quality. Text, vector graphics, and layout remain sharp. Image-heavy PDFs may see slight quality adjustments to achieve meaningful size reduction, but the result is optimized for readability and professional use.
Is there a file size limit?
The maximum upload size is 25 MB, which covers the vast majority of contracts, forms, and legal documents. If your file is larger, consider splitting it into smaller sections first using our free PDF split tool.
How does the compression work?
The compressor runs multiple optimization profiles against your PDF. It optimizes embedded images, removes duplicate resources, compresses fonts, and subsets unused characters. The profile that produces the smallest output is selected and returned as your download.
Are my files stored on the server?
Files are processed temporarily during compression and deleted immediately after the compressed PDF is returned. Nothing is stored on the server after you download your file.
