Encoding one URL at a time is fine until you have a spreadsheet column of fifty of them. This tool processes an entire list at once — one line in, one line out, in the same order.
What Is the Bulk URL Encoder/Decoder?
Bulk URL Encoder/Decoder is one of the tools in WebdevToolbox’s Encoding & Decoding category. Paste a list of URLs (or any text), one per line, and get every line encoded or decoded at once.
How to Use It
- Open the tool at /tools/batch-url-encode.
- Choose Encode or Decode.
- Paste your list, one item per line, into the input box.
- Copy the output — line order and count are preserved exactly.
Key Features
- Per-line independence — a malformed line is flagged with
[ERROR]instead of blocking the rest of the batch. - encodeURIComponent vs. encodeURI toggle — choose whether structural URL characters (
/,:) get encoded too. - Live processing — updates as you type or paste.
- Copy all — one click copies the entire output block.
When to Use the Bulk URL Encoder/Decoder
- Cleaning up a list of URLs from a spreadsheet or CSV export before importing them elsewhere.
- Decoding a batch of logged query strings to make them human-readable.
- Preparing query parameter values in bulk for a script or config file.
