Compress PDF Files Online
FileVance PDF Compressor reduces large document sizes to meet strict upload limits for email attachments, job portals, school submissions, and government applications.
Large PDF files often exceed portal size limits due to uncompressed embedded raster graphics and redundant structural objects. FileVance analyzes PDF streams, optimizes embedded photos, and cleans structural metadata while keeping vector text and line art razor-sharp. You can choose from standard compression presets (Strong, Recommended, Light) or input an exact target file size ceiling in KB or MB. Real-time before-and-after byte comparisons display exact savings.

Frequently Asked Questions
How does FileVance compress PDF files without making text blurry?
PDF compression targets heavy embedded raster photos and cleans redundant metadata streams. Vector text, fonts, and digital signatures remain uncompressed vector paths, ensuring sharp readability.
Can I specify an exact target file size in KB or MB?
Yes. You can switch to the target size mode and enter your required ceiling (such as under 200 KB or 1 MB) to pass strict application portal requirements.
Is there any limit on how many PDFs I can compress?
No. You can compress as many PDF documents as you need directly in your browser without daily quotas or subscription requirements.
Are my sensitive documents uploaded to any remote server?
No. FileVance processes all PDF compression locally inside your web browser memory. Documents and personal information never leave your computer or phone.
What is the difference between Strong and Recommended compression?
Recommended compression balances substantial file size savings with high visual fidelity. Strong compression aggressively downsamples embedded photos for maximum size reduction when meeting strict upload limits.
