(pxto.io) Pixels Converter is a collection of free, powerful tools that you can use to convert PIXELS into any units, such as Pixels to EM, Pixels to rem, px to pt, and many more.
What Is a Pixel (px)?
A pixel is the smallest addressable physical element of a digital image or display device. The term is abbreviated as px and is also referred to as a pel or picture element (PE).
In digital imaging, pixels are arranged in a regular two-dimensional grid. Each pixel represents one sample point of an original image and holds a specific color or intensity value.
In color imaging systems, a pixel's color is typically described by three component intensities: red (R), green (G), and blue (B). These RGB values combine to produce the full range of colors visible on a digital display.
Why do we need a Pixel Converter?
Different tools, platforms, and workflows speak different unit languages. A design file shows pixels. CSS needs rem. A print brief asks for millimeters. An Android layout requires dp. A PDF expects points.
Without a converter, you are doing manual math, dividing by 16, multiplying by 2.54, and accounting for DPI every single time. One wrong calculation breaks a layout, misaligns a print file, or ships the wrong asset size.
pxto.io eliminates that. One place, every unit, instant results.

Frequently Asked Questions
What units can I convert on pxto.io?
px, rem, em, %, vw, vh, vmin, vmax, svh, dvh, lvh, pt, pica, twip, cm, mm, inches, feet, Q, dp, sp, dip, fr, cqw, cqh, ch, ex, lh, cap, and more. Every CSS, print, and mobile unit in one place.
What is the difference between px and rem?
px is a fixed unit; it does not change when the user adjusts browser font settings. rem is relative to the root font size (usually 16px), so it scales with user preferences. rem is preferred for accessible, responsive typography.
What is the difference between em and rem?
em is relative to the parent element's font size and can compound through nesting. rem is always relative to the root (HTML) element, making it more predictable. Use rem for site-wide consistency, em for component-specific scaling.
What is the difference between vw and vh?
vw (viewport width) is 1% of the browser window's width. vh (viewport height) is 1% of the browser window's height. Use vw for horizontal fluid sizing, vh for full-height sections, and vertical layouts.
What is the difference between DPI and PPI?
DPI (dots per inch) measures print density how many ink dots a printer places per inch. PPI (pixels per inch) measures screen density, how many pixels fit in one inch of display. For screen work, use PPI; for print, use DPI.
What is dvh, and why is it better than vh on mobile?
dvh (dynamic viewport height) adjusts in real time as the mobile browser UI (address bar, navigation) appears or hides. vh is fixed at page load and can cause layout overflow on mobile. Use dvh for reliable full-screen mobile layouts.
What is dp in Android?
dp (device-independent pixel) is an Android unit that scales with screen density so UI elements appear the same physical size across all devices. At MDPI (160 DPI), 1dp = 1px. At XXHDPI (480 DPI), 1dp = 3px.
How many pixels is an A4 page?
At 300 DPI: 2480 × 3508 px. At 96 DPI: 794 × 1123 px. At 72 DPI: 595 × 842 px. The pixel count changes with DPI. Use the A4 to pixels converter for any custom resolution.
How do I convert px to pt?
Multiply the pixel value by 0.75. At 96 DPI, 1px = 0.75pt. So 16px = 12pt. Use the px to pt converter above for instant results.
What is a twip?
A twip is 1/20 of a typographic point, or 1/1440 of an inch. It is used in RTF documents, LibreOffice, and legacy Visual Basic applications as a screen-independent measurement unit.
What is a pica in typography?
A pica is a print typographic unit equal to 12 points or 1/6 of an inch. It is used in professional print design software like InDesign and Illustrator. 1 pica = approximately 16px at 96 DPI.
Can I use this converter for Figma or Sketch values?
Yes. Figma and Sketch both work in pixels. Use this converter to translate pixel values from your design files into the correct CSS units for your codebase: rem, em, vw, pt, or any other unit.
What base font size should I use for rem conversion?
The browser default is 16px. Most projects use 16px as the root font size. Some projects set it to 10px (so 1rem = 10px) for easier mental math. Check your CSS html { font-size: } value and enter it in the base font field of the converter.
