CHOOSE WITH CONFIDENCE

Make the right tool part of your workflow

Start with the result you need. Each tool below has its own settings, worked example, and troubleshooting advice so you can check the output before using it.

Understand the length and reading effort of your draft. Words are counted as groups separated by whitespace. Character counts include spaces and line breaks; emoji may contain multiple Unicode code points.

JSON formatter

Turn dense JSON into data you can inspect. JSON requires double-quoted property names and does not allow comments or trailing commas. JavaScript numeric precision applies; large integer identifiers should be strings.

Base64 encoder / decoder

Encode readable text for transport, then decode it safely. Base64 is an encoding, not encryption. Anyone can decode it. Decoding is intended for valid UTF-8 text, not arbitrary binary files.

File checksum

Compare file contents with a SHA-256 fingerprint. Matching checksums indicate matching bytes, but do not establish that a file is safe. Large files require memory because the browser reads the file at once.

A SIMPLE ROUTINE

From task to finished result

STEP 01

Choose your starting point

Select the tool that matches your input and the change you want. Read its format requirements before selecting a file or entering values.

STEP 02

Adjust and process

Follow the tool’s quick-start steps. Check the selected files, units, or options before generating a result; a small settings change can affect the output.

STEP 03

Review and save

Inspect the result and download or copy it where offered. Keep your source file and choose a clear filename so you can find the finished version later.

HELPFUL ANSWERS

Frequently asked questions

A little clarity before you get started.

Which files tool should I choose?

Choose by the change you need. The tool cards explain each operation, and every tool page includes controls, a worked example, practical use cases, and specific limitations.

Can I use several tools in sequence?

Yes. Download or copy the result from the first tool, then use it as input in a compatible tool. Check the format and quality at each stage and keep the original separately.

Do these tools require an account?

No. All tools are available without signing in. An optional account saves your favorite tool list across devices.

What if I cannot get a result?

Read the troubleshooting section on the tool page, check the input format and any size limits, and try a smaller sample. Browser support and available device memory can affect file operations.
