About PDF Compression
PDFs are container files that can embed images, fonts, and metadata. Compression works by downsampling embedded images, stripping redundant font subsets, and simplifying metadata. Text remains fully readable and selectable — only image content gets smaller.
Portal Uploads
Government portals, university applications, and job submission systems often cap PDF uploads at 100KB–500KB. Our target-size pages hit those limits automatically.
Email Attachments
Gmail caps attachments at 25MB, Outlook at 20MB. Compress your PDF to under 20MB and email it anywhere.
Scanned Documents
Scanned PDFs are often 5–50MB because each page is a full-resolution image. Aggressive compression cuts them down to under 500KB per page.
Preserves Structure
Page count, bookmarks, and internal links are preserved. Text remains selectable and searchable.
