Pro Tip: Drag thumbnails left or right to set which photo appears first.

Choose Layout Direction

Select 'Horizontal' to place photos side-by-side (ideal for Before/After photos) or 'Vertical' to stack them (ideal for 2-sided ID cards).

Pro Tip: Enable 'Match Dimensions' to automatically scale both pictures to equal height or width.

Customize Border and Spacing

Adjust the gap spacing between photos and choose a clean border color (e.g. white or transparent).

Pro Tip: A 10px white border creates a clean, professional split between images.

Frequently Asked Questions

How do I combine the front and back of my ID card onto one photo for an application?

Upload the front photo and the back photo into the Merge Images tool. Select 'Vertical' layout and set background to white. Both sides will be cleanly stitched into a single image accepted by all verification portals.

Can I create a Before & After comparison picture?

Yes! Select 'Horizontal' layout to place your 'Before' photo on the left and 'After' photo on the right. Both images will automatically align to the same height.

Are my sensitive ID card pictures uploaded to your servers?

No. The image stitching is rendered 100% client-side via HTML5 Canvas in your browser memory. Your ID cards, licenses, and passports never leave your computer or phone.
