PDF Compressor - Reduce PDF Size to Your Exact Target Size

Tired of "file too large" errors? PDF Compressor is a fast, free, offline PDF compressor that shrinks PDF files to the exact size you need. Select a file, set your target, and let the engine reduce PDF size while keeping text sharp and layouts intact - all on your device, no uploads, no account required.

Compress PDF to an exact target size

Most PDF compressors only offer vague quality presets. PDF Compressor lets you choose a precise target file size between 1MB and 50MB. The engine compresses images, subsets fonts, and optimizes the document structure until your PDF file reaches the size you set. No guesswork - just the result you asked for.

How to compress a PDF file

1. Tap Select File and pick any PDF (1MB - 200MB)
2. Set your target size with the slider (1MB - 50MB)
3. Tap Compress and watch the live progress bar
4. Preview the result, then save or share your smaller PDF

Private by design

PDF Compressor processes everything locally and offline. No files are uploaded to servers, no account or registration is required, and no personal data is collected. Use it for sensitive documents with peace of mind.

Important note

Compression results depend on the source file. Text-based PDFs can often be compressed well below 2MB, while heavily scanned or image-rich documents may need a higher target size to stay readable. Compressed PDFs are best viewed on screen rather than used for professional printing.
