Convert Integers to Octal Base

The Convert Integers to Octal Base tool takes decimal integers and converts them to base-8 (octal) format. It supports positive and negative values, handles multiple lines of input, and gives you clean octal output instantly.

Whether you’re working with legacy systems, Unix permissions, low-level debugging, or number base conversions, this tool gives you fast, accurate results right in your browser.

You can paste numbers in manually, import a text file, and toggle formatting options like padding octal values to a fixed width.

Paste your input above or import a file below.

Supported file types: .txt, .csv, .tsv, .log, .json, .xml, .md, .ini, .yaml, .yml, .html, .htm, .css
Total converted: 0
Options
Ignore non-integers
Pad to 4 digits
Maximize output

How to Use:

  • Paste or type one integer per line into the Input Integers box
  • Use Choose File to import a plain text file with decimal values
  • Toggle Ignore non-integers to skip invalid entries (e.g., text or malformed lines)
  • Enable Pad to 4 digits to left-pad octal values with zeros (e.g., 7 becomes 0007)
  • Use Maximize output to expand the output area if you’re working with large input
  • Click Convert to generate the octal result (live preview is automatic)
  • Use Copy Output or Export to File to save results
  • Click Clear All to reset everything

What Convert Integers to Octal Base can do:

This tool handles decimal-to-octal conversion line by line. You can work with large lists, include negative values, and decide how strict the parser is with non-numeric input. The padded format is especially useful for aligning output or simulating fixed-width byte fields.

Example:

Input:

10
255
-8
0

Output:

12
377
-10
0

With Padding ON:

0012
0377
-0010
0000

Common Use Cases:

Use this tool to convert decimal integers to octal for system configurations, binary tools, assembly coding, or numeric formatting tasks. Developers use it when working with Unix permissions, firmware values, or base-shifting logic. Teachers and students use it for learning number systems or generating base conversion worksheets.
