✂️ File Splitter (by size)
Cut any file into numbered chunks of a size you choose — useful for email attachment limits, USB drives with a small file-size cap, or upload forms that reject big files. Use the File Joiner to put the parts back together.
1. Choose a file
📁
Click to choose, or drag & drop a file
Nothing is uploaded — split locally in your browser.
The file will be sliced into equal parts of this size (the last part is whatever's left over).
2. Parts
Parts are named yourfile.ext.part1, yourfile.ext.part2, … Download them individually, or use "Download all parts" — browsers throttle rapid automatic downloads, so that button spaces them out by about half a second each and may still prompt you to allow multiple downloads.
Choose a file and click "Split file" to see parts here.
