Text & Document Tools.
5 free browser-based tools for writing, document conversion, and file handling - all offline, nothing uploaded.
Writing and document work generates a steady stream of small conversion and analysis tasks. How many words is this article? Does this bio fit within the character limit? Can you turn this spreadsheet into a CSV without installing anything? The text and document tools on Powertoys.Online handle these tasks instantly, in your browser, with nothing sent to a server.
The Word Counter counts words, characters, sentences, and paragraphs in any block of text. It also provides an estimated reading time based on average adult reading speed and lists the most frequently used words — useful for checking keyword density in content writing. Paste or type directly in the text area and results update in real time.
The character counter mode of the same tool tracks characters with and without spaces — essential for platform-specific limits like Twitter posts, Meta ad headlines, YouTube video titles, and form fields with hard character caps. You see the count update as you type so you always know exactly where you stand.
The Case Converter changes pasted text between developer and writing formats such as camelCase, PascalCase, snake_case, kebab-case, sentence case, Title Case, URL slugs, and more. It is useful for turning headings into identifiers, normalizing labels, and converting lists line by line.
The Excel to CSV converter handles a common data workflow: turning an .xlsx spreadsheet into plain CSV files for import into a database, analytics platform, or data pipeline. Upload your workbook and each sheet is extracted as a separate downloadable CSV file — no Excel installation required, no server upload. The conversion happens entirely in your browser using the SheetJS library.
The JPG and PNG to PDF converter bundles multiple images into a single PDF document, in your browser, with no upload to any server. Useful when you need to merge screenshots, scanned documents, or photo batches into a single deliverable — for client reports, application submissions, or archiving. Images are combined in the order you arrange them and the resulting PDF is downloaded directly to your device.
All text and document tools on Powertoys.Online are private by design. Your text, spreadsheets, and image files are never transmitted anywhere. Nothing is retained after you close the browser tab.

Frequently Asked Questions
- What counts as a word in the word counter?
- Words are counted as sequences of characters separated by whitespace. Hyphenated words (such as "up-to-date") are counted as a single word. Numbers count as words. Punctuation attached to a word is stripped before counting.
- Does the Excel converter support files with multiple sheets?
- Yes. When you upload an .xlsx file with multiple worksheets, each sheet is converted to a separate CSV file, which you can download individually. Sheet names are used as the CSV file names.
- What image formats does the PDF converter support?
- The converter supports JPG (JPEG) and PNG files. You can combine images of both formats in a single PDF. Each image is placed on its own page, sized to fit the page with the original aspect ratio preserved.
- Does the Excel converter upload my spreadsheet to a server?
- No. The Excel to CSV conversion runs entirely in your browser using client-side JavaScript. Your spreadsheet file is read locally and never transmitted to any server. This makes it safe to use with confidential business data.
- What is the maximum file size for the PDF converter?
- The PDF converter is limited by your browser's available memory rather than a fixed server-side cap. In practice, files up to several hundred megabytes work well in modern browsers. Very large image files may slow down the conversion depending on your device.
