Compress Photo for Bank Document

Bank KYC submissions, insurance claims, healthcare portals (Ameli, French healthcare, etc.) require document scans to be clear and readable, but under file size limits. Reduce your scan to 400×500 px and 50 KB–2 MB while maintaining text clarity and compliance.

Bank & Insurance Document Size Limits

Service / Portal	Typical Size Limit	Minimum Dimensions	Recommended Target
Ameli (French healthcare)	1–2 MB per file	400×500 px min (300 DPI equiv.)	800 KB
Bank KYC (Know Your Customer)	1–3 MB per document	400×500 px (ID, passport, proof of address)	1–1.5 MB
Insurance claim portal	1–2 MB per upload	400×500 px	800 KB
Medical/dental patient portal	2–5 MB per file	400×500 px	1–2 MB
Mortgage or loan application	1–3 MB per document	400×500 px (ID, paystubs, documents)	1 MB

Quick Example: Before & After

Before: High-res passport scan (300 DPI, 2400×3000 px) = 4.2 MB
Action: Resize to 400×500 px, reduce quality to 80%
After: 180 KB — text remains clear, easily readable
Result: Bank KYC portal accepts upload instantly; no re-submission required

Step-by-Step Guide

Scan or photograph the document clearly. Use good lighting, hold the camera straight (no angle), and ensure the document fills the frame. Blur or glare will compress poorly and may be rejected by the portal.
Upload the scan or photo to this tool. Drag and drop or click to select. All processing happens in your browser — nothing is stored or sent to a server.
Resize to 400×500 pixels minimum. This size maintains text clarity while reducing file size dramatically. Document portals may reject images smaller than 300×400 px.
Set quality to 80%. For document scans, 80% quality preserves text sharpness and barcodes. Do not go below 75% for documents — text legibility suffers.
Use JPEG format. JPEG is the standard for document uploads. It compresses scans efficiently while keeping text readable. PNG will create much larger files.
Check the preview carefully. Before downloading, zoom into the preview and confirm text is still legible. Look for any pixelation or blur on critical info (ID number, dates, etc.).
Download and upload to the portal. Click "Download," then upload to the bank, insurance, or healthcare portal. Most portals confirm receipt within seconds.

Pro Tips

Ensure uniform lighting when scanning. Harsh shadows or glare make text harder to read after compression. Use a desk lamp or natural window light, positioned at a 45° angle to the document.
Compress at 80–85% quality for sensitive documents. Never drop below 75% for bank documents, passports, or medical records. Text clarity is non-negotiable for compliance and OCR systems.
Use a document scanner app if possible. Apps like Adobe Scan, CamScanner, or your phone's built-in scanner straighten the image and adjust perspective automatically, resulting in cleaner uploads.
Batch compress multiple documents. If submitting 5 ID pages, paystubs, and proof of address, use Pro to compress all at once. Free tier caps at 5 images; Pro is unlimited.
