常见问题

FAQ

长图文字模糊怎么办？

请确保导出时选择300 DPI及以上分辨率，并关闭PDF压缩选项；PDFnoted默认保留原始矢量文本渲染，若源PDF含扫描件，请先用OCR识别再转换。

能调整长图的页面间距或边框吗？

可以。PDFnoted高级设置中提供「页间空白（px）」和「外边距」滑块，支持0–50px精细调节，让长图更美观易读。

转换后的长图太大，发微信失败怎么办？

PDFnoted内置「微信优化模式」：勾选后自动压缩长图至<5MB，同时保持文字清晰可读，兼容微信图片上传限制。

Why does text in the long image look blurry?

Set export DPI to ≥300 and disable PDF compression. PDFnoted preserves vector text rendering by default; for scanned PDFs, run OCR first before conversion.

Can I customize spacing or borders between pages in the long image?

Yes. In PDFnoted’s Advanced Settings, use the ‘Page gap (px)’ and ‘Outer margin’ sliders (0–50px) to fine-tune layout for better readability and aesthetics.

The long image is too large to send on WeChat — what can I do?

Enable PDFnoted’s ‘WeChat-Optimized Mode’ — it compresses the long image to <5MB while preserving text legibility, fully compliant with WeChat’s upload limits.
