Most used tools
The tools people reach for most often, across every category.
JPG to PNG
Convert JPG photos to lossless PNG files directly in your browser. Original dimensions are preserved and nothing is uploaded.
PNG to JPG
Turn PNG images into smaller JPG files. Choose the quality level and the background color used for transparent areas — all processed locally.
WebP to JPG
Convert WebP images into JPG files that open in any application, older device or upload form. Conversion happens locally in your browser.
Image Compressor
Shrink image file sizes by re-encoding at a quality level you control. Works with JPG, PNG and WebP, entirely in your browser.
Compress JPG
Reduce the size of JPG photos by re-encoding them at a lower quality setting, with the exact saving shown for every file.
Image Resizer
Resize images to exact pixel dimensions or by percentage. The aspect ratio is locked by default so photos are never accidentally stretched.
HEIC to JPG
Turn iPhone HEIC photos into universally compatible JPG files. Convert up to 20 photos at once, adjust the quality, and download — nothing is uploaded anywhere.
JPG to PDF
Turn one or many JPG photos into a single PDF. Drag files to reorder pages, pick a page size and margins, and download — all without uploading anything.
Merge PDF
Combine two or more PDF files into a single document. Drag files to set the order — merging happens locally, so contracts and reports never leave your device.
Split PDF
Break one PDF into several smaller documents by entering page ranges such as 1-3, 5, 7-10. Each range becomes its own downloadable PDF.
PDF to JPG
Turn each page of a PDF into a high-quality JPG image. Pick the resolution and quality, then download individual pages or grab everything as one ZIP — entirely in your browser.
PDF to Word
Extract the text of a PDF into an editable Word (.docx) file you can open in Microsoft Word, Google Docs, or LibreOffice — without uploading the document anywhere.
PDF to PowerPoint
Turn a PDF into a ready-to-present PowerPoint file. Every page becomes one slide showing the page exactly as designed — fonts, charts, and layout preserved.
Word to PDF
Turn Word documents into shareable PDFs without uploading them anywhere. Headings, bold, italics and lists carry over — and you can convert several .docx files in one go.
Word Counter
Paste or type text to get a live count of words, characters, sentences and paragraphs, plus an estimated reading time.
Character Counter
See a live character count — with and without spaces — as you type, plus line and word counts for context.
JSON Formatter
Paste minified or messy JSON and get a cleanly indented, readable version. Invalid JSON produces an error with the line and position of the problem.
CSV to JSON
Turn CSV data — pasted or from a file — into a JSON array of objects, using the header row as keys. Quoted fields and embedded commas are handled correctly.
Password Generator
Create strong random passwords with control over length, symbols, digits and ambiguous characters. Generated locally with cryptographic randomness — never transmitted.
QR Code Generator
Create a QR code from any text or URL and download it as PNG or scalable SVG. No watermark, no expiry — the code is generated in your browser.

Remove Duplicates
Clean duplicate entries out of any list — emails, URLs, keywords, log lines. The first occurrence of each line is kept and the rest are removed.
Sort Lines
Put any list in order: alphabetical (A–Z or Z–A), natural numeric order, or by line length — with one click.
Remove Extra Spaces
Clean up messy whitespace: collapse repeated spaces, trim the ends of lines, and remove empty lines — each cleanup individually selectable.
Developer Tools
Small, dependable utilities for everyday development work. Every tool runs client-side, so API responses, credentials and data samples never leave your machine.
JSON Formatter
Paste minified or messy JSON and get a cleanly indented, readable version. Invalid JSON produces an error with the line and position of the problem.
JSON Minifier
Strip every unnecessary space and line break from JSON to get the smallest valid representation — with the size saving shown.
JSON Validator
Check whether a JSON document is valid. Errors are reported with line and column, plus a plain-English explanation of the likely cause.
CSV to JSON
Turn CSV data — pasted or from a file — into a JSON array of objects, using the header row as keys. Quoted fields and embedded commas are handled correctly.
JSON to CSV
Convert a JSON array of objects into CSV that opens cleanly in Excel or Google Sheets, with correct quoting and a stable column order.
URL Encode/Decode
Percent-encode text for URLs, or decode %20-style strings back into readable text. Choose component encoding (strict) or full-URL encoding.
Why browser-based matters
Most online converters upload your file to a server you know nothing about. These tools do not have a server to upload to.
No uploads, ever
Files are read and processed by your own browser. Nothing is transmitted to a server.
Instant results
No upload queue and no round-trip, so most conversions finish before a server would have finished receiving the file.
Free, no account
No sign-up, no email, no watermarks and no trial limits. Close the tab and nothing is retained.
Works everywhere
Runs in any modern browser on Windows, macOS, Linux, Android and iOS. Nothing to install.
How to verify this yourself
You should not have to take a privacy claim on trust. Open your browser's developer tools, switch to the Network tab, then run any tool on this site with a file. No request carrying your file will appear, because the conversion happens in JavaScript inside the page you have already downloaded. You can also disconnect from the internet after the page loads — the tools keep working.
