URL Encoder and Decoder
Percent-encode or decode URLs and query parameters. Choose component or full-URI encoding and inspect query strings.
Component mode escapes : / ? & = too — use it for a single parameter value.
About URL Encoder
URLs may only contain a limited set of characters. Anything else — spaces, ampersands, accented letters, emoji — has to be percent-encoded before it can travel safely in a link. This tool encodes and decodes in both the component and full-URI modes, and breaks a pasted URL into its parts so you can see exactly what each parameter contains.
How to use it
- Paste a URL or a single parameter value.
- Choose Component mode for one value, or Full URI to preserve the structure.
- Encode or decode, then copy the result.
Frequently asked questions
What is the difference between the two modes?
Component mode escapes everything including : / ? & = and is right for a single parameter value. Full URI mode leaves those structural characters alone so a complete URL stays usable.
Why is a space sometimes %20 and sometimes +?
%20 is correct everywhere in a URL. The + form is only valid inside a query string encoded as application/x-www-form-urlencoded, which is how HTML forms submit.
Do I need to encode the whole URL?
No — encoding a whole URL in component mode breaks it. Encode only the individual values you are inserting into it.

A Systematic Investment Plan is a standing instruction to put a fixed amount into a mutual fund on the same date each month. That is the whole idea. It is not a product you buy, not an asset class, and not a scheme with a guaranteed rate — it is a schedule. The returns come from whatever the underlying fund holds.

BMI Calculator guide
Body Mass Index is weight in kilograms divided by height in metres squared. That is the whole calculation. It was devised in the 1830s by the Belgian statistician Adolphe Quetelet, who was explicitly describing populations rather than assessing individuals — a distinction that matters enormously and gets lost constantly.

Almost every percentage problem is one of four shapes. Knowing which one you are looking at is most of the work, because each has a different formula and mixing them up is where the wrong answers come from.
