How does client-side image conversion work?

We load your image file, draw it on an HTML5 canvas, and call canvas.toBlob() or canvas.toDataURL() with your chosen target MIME type and export quality to export the formatted image locally.

Does the HEIC converter upload files?

No. HEIC parsing is handled entirely in your browser using the heic2any library. No server bandwidth is consumed, and your private photos remain secure.

Are there file size limits for data format converters?

There are no artificial limits. Conversions are processed in-memory in your browser, meaning very large files (tens of megabytes) will depend on your local machine memory.

Everything About File Conversion Tools

Working across different tools and platforms requires transcoding images, data schemas, encodings, and color codes constant. PixelTools's File Conversion Tools collection brings together these tasks into a fast, unified, and client-side conversion interface.

No more copy-pasting code fragments or uploading private CSV data sheets to untrusted third-party services. Convert data formats (CSV, JSON, XML, YAML, Markdown), transcode images, and translate color models securely in your browser.

Structured Data Format Translators

Developers, data analysts, and writers constantly convert data between schemas. The CSV to JSON and JSON to CSV converters let you customize delimiters, headings, and nesting structures. The XML to JSON and JSON to XML tools traverse document nodes recursively using the browser's native DOMParser APIs.

For config files and documentation formats, we provide YAML-to-JSON, JSON-to-YAML, HTML-to-Markdown, and Markdown-to-HTML engines. The Markdown engine compiles markdown syntax to formatted HTML code and provides a live styled preview pane.

Image Conversions & Color Profiles

The Unified Image Converter supports fast transcoding between JPEG, PNG, WEBP, BMP, and GIF formats. Adjust quality levels for lossy exports to balance file sizes. We also support Apple's HEIC file conversions to JPEGs using heic2any.

Designers and front-end developers working with brand guidelines can use the Unified Color Converter. Inputting a value in HEX, RGB, HSL, or CMYK instantly calculates and syncs translations across all other color models, complete with a color picker and color swatch.
