Frequently Asked Questions

Why do expense portals restrict invoice uploads to 200KB?

Enterprise accounting databases archive millions of expense attachments and strictly cap single-file size to reduce server storage overhead.

Will invoice numbers and red stamps become blurry?

No. ImgMin's document engine preserves high-contrast edges, keeping invoice numbers, QR codes, and red stamps sharp and legible for OCR and human review.

Are financial details and bank account numbers secure?

Absolutely. ImgMin operates 100% locally in your browser. Disconnect your internet to test: zero bytes leave your device.
