عن هذه الأداة

This tool compresses PDF files by reducing image resolutions, downsampling embedded images, and optimizing encoding to lower file size while preserving readability and layout.
Conceptually, the tool parses the PDF structure, applies a selected compression profile (low, medium, high), reposts fonts via subsetting when requested, and outputs a compact document.
Audience and value: researchers, marketers, students, and administrators who need efficient sharing, archiving, or submission of multi-megabyte PDFs.
Core features and use cases include a single-file workflow and optional batch processing, predefined presets, font subsetting, metadata handling, and size-targeting with transparent reporting for quality assessment.

Frequently Asked Questions

اعثر على إجابات سريعة

What happens to metadata?

By default metadata is preserved; you may disable via an option to strip metadata. The output includes a metadata status indicating what was retained or removed, helping you verify sensitivity.

Can I control the amount of compression?

Yes, via predefined levels (low/medium/high) or by specifying a target size. The tool iteratively adjusts image downsampling, color depth, and font subsetting to approach the goal while avoiding excessive degradation.

Is the tool secure for sensitive documents?

Processing occurs on secure servers; inputs are not used for training. Data retention is limited to processing; for highly sensitive material consider on-premises solutions if available.

What input formats are supported?

Only PDF inputs are supported; other formats are rejected with a clear error. Output is a compressed PDF.
