Frequently Asked Questions
Everything you need to know about reducing PDF file size online.
How do I compress a PDF to 100kb or 200kb without losing quality?↓
To reach strict upload targets like 100kb, 200kb, or 500kb required by job portals and government websites, upload your file and select the 'EXTREME COMPRESSION' preset. It intelligently downsamples raster images while preserving vector outlines for all text and fonts so your document remains 100% readable.
How much can I reduce my PDF file size?↓
The reduction percentage depends on the document contents. Scanned documents and image-heavy files regularly see a 50% to 85% size reduction. Text-and-vector documents generally shrink by 20% to 40% through stream deduplication and metadata pruning.
Will compressing a PDF make the text blurry?↓
No. Vector typography and fonts are preserved with original mathematical precision at any zoom level. Only heavy bitmap images and photos are optimized, maintaining a crisp, professional appearance.
Which compression level should I choose?↓
We recommend 'RECOMMENDED COMPRESSION' for almost every file. It delivers an optimal balance between significant file size reduction and pristine visual quality. If you have an urgent email limit or portal cap, choose 'EXTREME COMPRESSION'.
Is it safe to compress sensitive tax filings and bank statements?↓
Yes, 100%. Unlike typical PDF compressor websites that transmit your files to cloud servers, TARGETROOT runs 100% locally in your web browser memory. Your confidential financial documents are never uploaded to any server or seen by anyone.
Is TARGETROOT PDF compressor free with no limits?↓
Yes, completely free. You can compress as many PDF files as you need with no daily restrictions, no email signups, and zero watermarks.
