Under the Hood: HTML5 Canvas 2D Sub-Pixel Matrix Engine
Hardware-accelerated coordinate partitioning, aspect ratio normalization, and anti-aliased clipping.
Partitioning & Geometry Calculation
The layout engine calculates cell bounding rectangles (x, y, width, height) by subtracting outer padding and inter-cell gaps from target canvas bounds. For heterogeneous photo resolutions, bicubic scaling preserves edge micro-contrast.
Sub-Pixel Clipping & Matrix Transformations
Rounded corners are achieved via path clipping with sub-pixel antialiasing. Individual tile rotations utilize 2D matrix transformations centered at the tile centroid, avoiding coordinate drift or fuzzy borders.
Asynchronous Memory Management
Images are ingested via ephemeral Blob object URLs that are systematically revoked when replaced to keep browser memory usage ultra-lightweight even when working with 20+ megapixel camera RAW conversions.
โ Frequently Asked Questions
Can I combine images with different dimensions and aspect ratios? โผ
Yes! You can choose between "Cover (Fill & Crop)" which automatically crops each photo to uniformly fit its tile, or "Contain" which shows the complete photo uncropped with balanced letterboxing.
How do I make a Before and After photo comparison? โผ
Upload your 2 photos, select the Side-by-Side layout, and switch the Badge Overlay dropdown to "Before" & "After". The tool automatically stamps clean badges on the top corners!
Is there a limit on how many images I can combine? โผ
There is no hard limit! You can combine 2, 4, 9, 16, or more photos into seamless custom column grids. Because processing runs locally in your browser, performance depends solely on your computer's memory.
Are my images uploaded to any remote server? โผ
Never. Like all BWTools.uk utilities, the Image Combiner executes 100% locally on your machine via HTML5 Canvas. Your photos never leave your device, ensuring total security and privacy.
