About this tool
Convert pixels to rems instantly. Free, bidirectional, and fully in-browser.
1 pixel equals 0.0625 rems — enter any pixel value to convert it to rems instantly. This Pixel to Rem converter is a client-side tool: it applies a single multiplication (rem = px × 0.0625) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert rems back to pixels. A reference table lists common pixel values already converted, and nothing you enter is sent to a server.
Open Pixel to Rem Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Pixel field.
Read the equivalent in rems in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert rems to pixels.
The result updates as you type, and the swap button flips the conversion to rem → pixel without reloading.
The conversion uses the precise factor (rem = px × 0.0625), so the number matches a manual calculation to the decimal places you choose.
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Everything runs locally in your browser — no upload, no account, no limit on conversions.
One pixel is 0.0625 rems. Multiply the pixel value by 0.0625 to convert. For example, 10 px = 0.625 rem.
rem = px × 0.0625. This tool applies it automatically and shows a worked example: 10 px = 0.625 rem.
Yes. Press the swap button, or type into the rem field, and the tool converts rems to pixels using the inverse of the same relationship.
It uses the standard CSS and print typography size definition (rem = px × 0.0625), not a rounded approximation, so results are exact to the number of decimal places you select.
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
