Frequently Asked Questions

1. Will the converted images be blurry?

Image sharpness depends on resolution settings: 300dpi maintains original PDF clarity; 72dpi is optimized for web use and may appear fuzzy when enlarged.

2. How large of PDFs can free users convert?

Free users can convert PDFs up to 200MB per file, max 3 files per session. VIP users support 500MB per file, 10 files per session, and unlock 500dpi ultra-high resolution.

3. Can I extract only images from the PDF, ignoring text pages?

Yes. First delete text-only pages with the Edit PDF tool, keeping only image-containing pages, then convert to reduce unnecessary outputs.

4. Will scanned PDFs become clearer after conversion?

No. Scanned PDFs are already image-based, so conversion preserves the original scan quality. You can enhance clarity with the Image Enhancement tool (VIP feature).

5. Do converted images have watermarks?

Free users receive a light “Micro PDF” watermark at the bottom of images. VIP users get watermark-free images suitable for commercial use.

6. Can I set different formats for different pages in one conversion?

Not currently supported. All pages in a single PDF must use the same format. For mixed formats, split the PDF first and convert separately.

7. Do converted images include text from the PDF?

Yes. Full-page conversion includes all content (text + images). To extract embedded PDF images separately, use the standalone Extract Images tool.
