FormatOwl guidesText and developer tools
Format data, edit text and work with common encodings.
Choose a category
- JSON and XML: format, convert and inspect structured data.
- Text: count, compare, deduplicate, sort and find or replace.
- Encoding: work with Base64, URLs and related formats.
- Passwords: generate passwords and work with hashes.
- QR codes: generate or scan QR codes and barcodes.
- Colors and SVG: convert colors and work with vector content.
- Skills commands: prepare commands from a form; you decide whether to execute them after copying.
A useful workflow
Start with a small sample to check the settings and output, then process the full input. When formatting JSON, fix syntax errors such as missing quotes or extra commas first. A formatter cannot infer the intended meaning of invalid data.
Privacy and limits
Free / Pro limits: images 10 / 20 MiB each, 50 / 100 MiB per task; PDFs 50 / 100 MiB and 100 / 200 pages; media 100 / 200 MiB; text, code and SVG 2 / 5 MiB; up to 10 / 50 inputs where supported. Workbench JSON: 2 / 32 MiB; other workbench operations: 1 MiB. Tool-specific safety limits still apply.
Processing runs in your browser, but copied results enter your device clipboard. Manage clipboard history and downloads yourself. The developer workbench is free; JSON format/validation allows Free 2 MiB / Pro 32 MiB, with 1 MiB for other operations.
Base64 is encoding, not encryption. Check QR contents before sharing. Hashing is also different from encrypted storage. Use a trusted device and browser for sensitive information.
