Advanced algorithms maintain quality while dramatically reducing file size
Fine-tune compression settings for your specific needs
Maintain document integrity with intelligent compression
Drag and drop your PDF file into the upload area or click to select it from your device.
Select from compression presets: Email (120 DPI), Web (200 DPI), Print (300 DPI), or Custom. See the estimated output size before compressing.
Click Compress to reduce the file size. Review the before-and-after size comparison, then download the optimized PDF.
Choose from Email, Web, Print presets or set custom compression levels to balance file size against visual quality for your specific needs.
Files are securely uploaded using encrypted connections, processed on our servers, and automatically deleted after processing completes.
See the original and compressed file sizes side by side with the percentage reduction, so you know exactly how much space you saved.
Server-side compression is fast, typically completing in seconds even for large documents. Encrypted upload and download happen quickly over modern connections.
Text remains crisp and selectable. Images are optimized intelligently, reducing size without introducing visible artifacts at standard viewing distances.
Email attachment limits are one of the most common reasons people compress PDFs. Most email providers cap attachments at 10-25 MB, and a PDF with high-resolution images or embedded graphics can easily exceed that. Compression can reduce file sizes by 50-80%, bringing oversized documents within acceptable limits without removing any content.
Web hosting and document management systems also benefit from compressed PDFs. Smaller files load faster for website visitors, reduce storage costs, and speed up document indexing. Companies that publish annual reports, product catalogs, or technical manuals online can significantly improve user experience by optimizing their PDFs before uploading.
Your documents are transmitted over an encrypted connection and automatically purged from our servers once processing is complete. We never store, share, or access your file contents. This makes the compressor safe for confidential documents such as financial reports, legal contracts, and patient records.
Reduction depends on the content of your PDF. Image-heavy documents typically see 50-80% reduction. Documents that are mostly text may see 10-30% reduction since text is already compact. The tool shows you the exact reduction before you download.
No. Text in PDFs is stored as vector data, which remains perfectly sharp at any zoom level regardless of compression. Only embedded raster images are optimized, and the quality settings let you control how aggressively images are compressed.
You can try, but the results will be minimal. If a PDF has already been optimized, there is little redundancy left to remove. The tool will show you the size comparison so you can decide if the additional compression is worthwhile.
No. Compression optimizes how data is stored within the PDF but does not remove pages, text, or images. All content remains intact and accessible in the compressed file.
Your file is securely uploaded over an encrypted HTTPS connection to our processing server. Once compression is complete and you download the result, both the original and compressed files are automatically deleted. We never retain, read, or share your documents.
