How to Reduce PDF Size After Conversion

Large PDFs are inconvenient to share. If your converted PDF is too big, try these practical steps to shrink it while keeping readable quality.

1. Resize images before conversion

If the source images are very large (camera photos), resize them to a maximum width of 1500–2000px — it's still high quality for printing and drastically reduces file size.

2. Lower image quality slightly

A quality setting of 70–85% often keeps images visually crisp but reduces bytes significantly. Our tool lets you adjust quality during conversion.

3. Use grayscale for documents

If your images are scanned documents (not color photos), convert to grayscale before embedding — that can cut size a lot.

4. Compress the final PDF

Use an online PDF compressor or a desktop app (Preview on Mac has export/compress options). For sensitive files, prefer client-side tools to protect privacy.

Quick checklist

• Resize large images
• Choose 70–85% quality for photos
• Use grayscale for text scans
• Compress final PDF if needed

Following these tips usually reduces file size without noticeable quality loss.
