👎🏼 Cons

Ads in free tier: The free version includes ads that can interrupt workflow and require dismissing during use. Upgrading removes ads for uninterrupted work. 💸

Advanced features behind paywall: OCR, batch processing, and advanced collaboration tools are gated behind premium plans, which may be necessary for heavy users. Consider the cost if relying on those functions. 🔒

OCR limits on low-quality scans: Accuracy drops with blurry or low-resolution images, requiring manual correction for some documents. Good originals yield best results. 📉

Large file performance: Very large or image-heavy PDFs can cause slowdowns or occasional crashes on older devices, impacting reliability under heavy loads. Keep backups for critical files. ⚠️

Basic editing constraints: Page-level editing and advanced layout changes are limited compared to full desktop PDF editors, so complex edits may require additional software. Plan for desktop tools when deep edits are needed. 🧾
