PDF compression is essential in today's digital workflow. Large PDF files can cause numerous problems, from failed email attachments to slow website loading times. Our free PDF compressor solves these issues by reducing file size while preserving document quality.
There are many situations where compressing a PDF file becomes necessary:
PDF compression uses intelligent algorithms to reduce file size without significantly affecting quality. The process typically involves image optimization (reducing resolution and applying efficient compression), removing duplicate or redundant elements, optimizing fonts and embedded data, and streamlining the PDF structure. Our tool analyzes your document and applies the most effective compression methods automatically.
One common concern about PDF compression is quality loss. Our compressor is designed to find the optimal balance between file size reduction and visual quality. For most business documents, presentations, and reports, you can achieve 50-80% size reduction with minimal perceptible quality difference. Text remains sharp and readable, while images are optimized intelligently based on their content and resolution.
Maximum compression is ideal for documents that will be viewed on screen rather than printed, internal documents where perfect quality isn't critical, archival purposes where storage space is limited, or documents with mostly text and few images. For high-quality printing or professional presentations, lighter compression may be more appropriate.
Your files are processed securely and automatically deleted after compression. We never access or store your documents.

Our compression technology reduces file size while preserving document clarity and readability.
Start compressing immediately without creating an account or providing personal information.
Compatible with all devices and operating systems. Compress PDFs on Windows, Mac, Linux, iOS, or Android.
To get the best compression results, start with properly formatted source documents. When creating PDFs from Word, PowerPoint, or other applications, avoid using unnecessarily high-resolution images. Most screen viewing only requires 150 DPI, while 300 DPI is sufficient for printing.
Before compression, remove any unnecessary pages, embedded objects, or metadata. This pre-optimization can significantly enhance compression effectiveness.
After compression, you'll see statistics showing original size, compressed size, and percentage reduced. These numbers help you understand the effectiveness of compression for your specific document type.
Documents with many images typically compress more effectively than text-only PDFs. Scanned documents often see the most dramatic size reductions since they contain high-resolution images that can be optimized significantly.
If a PDF is still too large after one compression, you can compress it again. However, each additional compression may result in diminishing returns and potential quality degradation. Generally, one or two compression passes are sufficient for most needs.
For extremely large files, consider splitting the PDF into multiple smaller documents before compression, especially if different sections serve different purposes.
Compression effectiveness varies by document type. Image-heavy documents (presentations, brochures, photo albums) often compress by 60-80%. Text-heavy documents (contracts, reports, articles) typically compress by 20-40%. Mixed content documents usually fall somewhere in between. Already optimized or previously compressed PDFs may not compress much further.
Choose your compression approach based on how the PDF will be used:
Yes, our PDF compression tool is completely free with no limitations. You can compress unlimited files without any charges, subscriptions, or hidden fees.
Our compression algorithm is designed to minimize quality loss. For most documents, the difference is barely noticeable, especially when viewed on screen. Text remains crisp and clear, while images are intelligently optimized.
Compression effectiveness depends on the original document. PDFs with many high-resolution images can be reduced by 60-80%, while text-heavy documents typically see 20-40% reduction. Documents already optimized may compress less.
Files under 20MB are processed directly in your browser for maximum security. Larger files are processed on our server but are automatically deleted immediately after compression.
Absolutely. Smaller files are processed locally in your browser without uploading. For larger files processed on our server, they're encrypted during transfer and permanently deleted immediately after compression. We never store, access, or share your documents.
Password-protected PDFs need to be unlocked before compression. You can use our Unlock PDF tool to remove protection if you have the password, then compress the file.
Most PDFs are compressed in just a few seconds. Processing time depends on file size and complexity, but our optimized algorithms ensure fast results even for large documents.
Currently, you can compress one PDF at a time. However, there's no limit to how many files you can compress consecutively. Simply process each file and download the results.
Yes, scanned PDFs often benefit most from compression since they typically contain large, high-resolution images. You can expect significant file size reduction for scanned documents.
No, compression only reduces file size by optimizing images and removing redundant data. Your PDF's layout, fonts, links, and formatting remain completely intact.
You can, but effectiveness will be limited. PDFs that have been previously compressed have less redundant data to remove. Each additional compression may yield diminishing returns.
No installation required. Our compression tool works entirely in your web browser. Just upload your PDF and download the compressed result - it's that simple.
