The quality of your final PDF depends entirely on the quality of your source images. If you start with blurry, poorly lit, or oversized photos, even the best converter can only do so much.
In this guide, we'll cover the essential steps to optimizing your images before you hit the upload button.
1. Choose the Right Format
- JPG/JPEG: Best for photos and complex images with many colors.
- PNG: Best for screenshots, logos, and images with text or transparency.
- WebP: A modern format that offers great compression; bottopdf fully supports it!
2. Correct Lighting and Contrast
If you are photographing documents (like receipts or contracts):
- Avoid Flash: Flash can create glare on glossy paper. Use natural, even lighting.
- Increase Contrast: Use a basic photo editor to slightly boost the contrast. This makes the text "pop" against the white background, improving readability in the final PDF.
3. Crop and Straighten
A professional PDF shouldn't show the wooden table or the carpet around your document.
- Tight Crops: Crop your images so only the relevant document is visible.
- Straighten: Ensure the document is aligned horizontally. Most smartphone "scan" apps do this automatically.
4. Resolution: Finding the Sweet Spot
- For Reading: 150 DPI (dots per inch) is standard for clear digital reading.
- For Printing: 300 DPI is required for crisp physical copies.
- For Email: Avoid "Ultra High Res" 20MB photos if you plan to merge 50 of them into one PDF.
5. The Upload Workflow on bottopdf
