Which one do you need?
- Video Bitrate & File Size Calculator
- Convert video bitrate and duration into a file size, or work backwards to the bitrate that hits a target size, with bits-per-pixel quality and upload time.
- Screen PPI / Pixel Density Calculator
- Work out screen pixel density from resolution and diagonal, plus dot pitch, panel width and height, megapixels, pixels per degree and maximum print size.
- Aspect Ratio Calculator
- Solve the missing width or height for any locked aspect ratio, reduce a resolution to its simplest form, and size letterbox or pillarbox bars in pixels.
- WCAG Color Contrast Ratio Calculator
- Calculate the WCAG contrast ratio between two colors, see each relative luminance, get AA and AAA pass or fail per criterion, and a suggested passing shade.
- HEX, RGB, HSL & CMYK Color Converter
- Convert a color between HEX, RGB, HSL, HSV and CMYK with every arithmetic step shown, plus CSS-ready strings and the sRGB relative luminance value.
- Image File Size Calculator (Bitmap & Compressed)
- Compute uncompressed bitmap size from pixel dimensions and bit depth, estimate the compressed file, count how many images fit a card, and size texture memory.
