PDF Compressor review
A straightforward free web tool for compressing up to 20 PDFs in one batch.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
PDF Compressor is a free, web-based tool for people who need smaller PDF files for websites, social networks, email, sharing, or storage. Users can select files or drag and drop them into the browser, with support for up to 20 PDFs at once. Compression starts automatically after upload, keeping the workflow focused on file reduction rather than configuration. The service is a practical fit for occasional document preparation and small batch jobs.
Its strongest feature is the combination of batch processing and simple retrieval. Each compressed PDF can be downloaded separately, or all completed files can be collected in a ZIP archive. That makes the tool useful when several documents need to be prepared together without repeating the upload process for every file. Automatic processing also removes the need to choose a compression mode or adjust settings, which suits users who prefer a short, direct workflow.
PDF Compressor is more limited for organizations that need local processing or integration with other systems. It supports the web only, with no offline desktop application and no API access. The service also does not provide selectable compression modes, so users have less control over how the output is produced. Uploaded files and generated conversions are automatically deleted after a maximum of one hour. Choose PDF Compressor for free, browser-based batch compression and ZIP downloads; choose another tool if desktop access, automation, or more compression controls are central requirements.
