ID Documents That Need Resizing for KYC
Passport Photo Page
High-resolution scans of passport bio pages are typically 3-8 MB at 300 DPI. KYC portals usually need them under 2 MB with specific pixel dimensions.
Resize to 600x600 px or the required dimensions and compress to under 2 MB. Text, MRZ code, and photo remain clear for automated verification.
Resize Passport PhotoNational ID Card (Front & Back)
Phone camera scans of ID cards produce 4-12 MB images. Both front and back sides need to meet the same size requirements, doubling the total upload.
Resize both sides to the required dimensions. Diwadi processes files locally so your ID number and personal details stay private.
Resize ID Card PhotoDriver's License
Driver's license photos taken with modern phone cameras are often 5-10 MB. Many KYC systems require images under 2 MB at specific resolutions.
Resize and compress to meet exact pixel and file size requirements. Holograms and security features remain visible after balanced compression.
Resize License PhotoSelfie / Liveness Photo
Selfies for liveness verification are often 3-8 MB from modern phone cameras. Platforms require specific dimensions and clear facial features for automated matching.
Resize to the required dimensions while preserving facial clarity. Compression keeps the image sharp enough for biometric verification.
Resize SelfieProof of Address Document
Utility bills, bank statements, and lease agreements scanned as images can be 5-15 MB. KYC portals need them under 2-5 MB.
Resize and compress scanned documents. Text remains readable at 150-200 DPI. Process sensitive documents offline for security.

Identity Documents Must Stay Private

No File Size or Daily Limits
Online resizers often limit file sizes and restrict free usage to a few images per day. Diwadi has no limits on file size or number of photos.
Instant Processing
No upload or download wait times. Resizing and compression happen instantly on your device, even for high-resolution scans.
Process All KYC Documents at Once
Drop all your KYC photos -- passport, ID card front and back, selfie, proof of address -- and resize them all in one batch.

Common Mistakes When Preparing KYC Photos
Using online resizers for identity documents
Uploading passport scans and ID photos to free online tools means your identity data passes through third-party servers. Use a desktop tool for sensitive documents.
Cropping important details
Some platforms require full document edges visible, including corners of the ID card. Resize without cutting off borders, MRZ codes, or security features.
Over-compressing until text is unreadable
Maximum compression can blur small text like ID numbers, dates, and MRZ codes. Always preview the compressed image. Automated KYC systems will reject blurry documents.
Wrong aspect ratio for selfie verification
Stretching or distorting a selfie to fit dimension requirements breaks biometric matching. Resize with proper aspect ratio locking to avoid verification failures.
Submitting wrong file format
Most KYC portals accept JPG and PNG only. HEIC photos from iPhones must be converted first. Diwadi can convert between image formats.
KYC Photo Preparation Checklist
- Check the platform's required photo dimensions (pixels)
- Check the maximum file size per image
- Check accepted formats (JPG, PNG -- not HEIC)
- Ensure the full document is visible with all four corners
- Resize to the exact dimensions required
- Compress to under the file size limit
- Preview the resized image -- text and numbers must be readable
- Verify MRZ code on passport is sharp and legible
- Ensure selfie is well-lit with face clearly visible
- Keep original uncompressed copies as backup
- Convert HEIC to JPG if using iPhone photos
- Test upload with one document before submitting all
Frequently Asked Questions
What size should ID photos be for KYC verification?
Most KYC platforms require photos between 200x200 px and 800x800 px, with file sizes under 2-5 MB. The exact requirements vary by platform -- always check the specific upload page for dimensions and size limits before resizing.
Is it safe to use online tools to resize KYC photos?
Online resizers require uploading your identity documents (passport, ID card, selfie) to external servers. For KYC documents containing sensitive personal data, desktop tools like Diwadi are safer because files never leave your computer.
How do I resize a passport photo for Binance KYC?
Binance accepts JPG and PNG under 5 MB. Open Diwadi, drop your passport photo, set the target dimensions (600x600 px works well), and compress to under 5 MB. Preview to ensure the MRZ code and photo are clear.
Why does my KYC verification keep failing?
Common reasons: image is too blurry after over-compression, wrong dimensions, file is too large, document edges are cropped, selfie is poorly lit, or wrong file format (HEIC instead of JPG). Resize with proper settings and preview before uploading.
Can I resize HEIC photos from my iPhone for KYC?
Yes. Diwadi can convert HEIC to JPG or PNG while resizing. Most KYC portals do not accept HEIC format directly, so conversion is necessary before uploading iPhone photos.
How do I resize both front and back of my ID card?
Drop both images into Diwadi at once. Set the same target dimensions for both. Both files will be resized in batch, ensuring they meet the same requirements for upload.
What DPI should KYC document photos be?
For screen-based KYC verification, 150-200 DPI is sufficient. Higher DPI means larger file sizes without visible benefit on screen. If scanning physical documents, scan at 300 DPI and let Diwadi resize to the required dimensions.
Will resizing affect automated KYC verification?
Proper resizing preserves enough detail for automated verification systems. Balanced compression keeps text, barcodes, MRZ codes, and facial features clear. Avoid extreme compression that makes small text unreadable.
How small can I compress an ID photo without losing quality?
A typical phone camera ID photo (4-8 MB) can be resized and compressed to 200-500 KB while keeping all text and features readable. Use balanced compression and preview the result before uploading.
Do crypto exchanges have different KYC photo requirements?
Yes, each exchange sets its own limits. Binance allows up to 5 MB, Coinbase up to 4 MB, and Kraken up to 5 MB. Dimensions typically range from 300x300 to 800x800 px. Always check the specific platform requirements.
