Free PDF Compressor

Yes! Our PDF compressor is completely free to use with no hidden fees, subscriptions, or usage limits. Compress unlimited PDF files with adjustable quality settings and download compressed PDFs instantly at no cost.

Compression results vary depending on your PDF content and quality settings. On average, you can reduce PDF file size by 40-90%. PDFs with many images compress better, while text-heavy PDFs have less room for compression. Our three quality levels (high, medium, low) offer different compression ratios to suit your needs.

You can upload PDF files up to 25MB in size. This limit ensures fast processing and optimal performance. If your file exceeds 25MB, try compressing it in multiple steps or removing unnecessary pages before uploading.

No, we do not permanently store your PDF files. Your files are temporarily stored on our secure servers only during the compression process and are automatically deleted shortly after. We prioritize your privacy and do not access, view, or retain your documents.

Use High Quality (150 DPI) for professional documents, presentations, or print materials where quality matters. Medium Quality (100 DPI) offers balanced compression for most use cases like email attachments and web uploads. Low Quality (72 DPI) provides maximum compression for large files where quality is less critical, such as draft documents or archived files.

No, our PDF compressor cannot process password-protected or encrypted PDFs. You must remove the password protection before uploading. This is a security measure to ensure we only process files you have full access to. Remove the password using PDF editing software, then compress the file.

High Quality (150 DPI) maintains excellent image clarity with moderate compression. Medium Quality (100 DPI) provides balanced results with good quality and smaller file size. Low Quality (72 DPI) prioritizes maximum file size reduction but may show reduced image clarity. The quality level affects image resolution and file structure optimization.

We use industry-standard security measures including HTTPS encryption for file uploads and automatic file deletion after processing. However, for highly sensitive or confidential documents (financial statements, medical records, legal contracts), we recommend using offline compression software. Our tool is best suited for general business documents, presentations, and non-sensitive materials.

No! Text in your PDF remains crisp and readable at all compression levels. Our compression primarily targets images, embedded graphics, and file structure. Text quality is preserved, ensuring your documents remain professional and legible after compression.

Currently, our PDF compressor processes one file at a time to ensure optimal quality and fast processing. You can compress multiple PDFs sequentially by uploading and compressing each file individually. Batch compression may be added in future updates based on user demand.
