नोट: स्कैन किए हुए इमेज-भरे PDF ज़्यादा घटते हैं, लेकिन अब क्वालिटी एकदम हाई रहेगी।
A PDF compressor is a tool designed to reduce the size of PDF files, making them easier to share, upload, or store. These tools are widely available online and accessible from any device with a web browser, without the need for installation or registration
How PDF Compressors Work
PDF compressors use several techniques to decrease file size:
Image Optimization: Reducing the quality and size of images within the PDF often achieves the biggest reduction in size.
Removal of Unused Items: Unused fonts, images, and redundant data can be stripped out.
Resolution Adjustments: Lowering the resolution (PPI) of images embedded in the PDF reduces its overall size, with options for basic or strong compression.
Grayscale Conversion: Converting colored images to grayscale can further reduce file size.
Benefits of Using PDF Compressors
Faster Sharing: Smaller files are easier to email or upload to websites that have size limits.
Storage Efficiency: Reducing file sizes saves storage space on your devices or cloud accounts.
No Quality Loss (Lossless Compression): Some tools offer lossless compression, but the file size reduction is typically smaller compared to lossy methods.
Privacy and Security: Quality online tools use encryption and delete your files after processing, ensuring security.
Choose your desired compression level—basic, strong, or custom.
The tool processes your file, reducing its size by optimizing images, fonts, and other elements.
Download the newly compressed PDF file. Some tools even allow batch processing for multiple files at once.
