Simply drag and drop your .heic photos into the uploader zone after selecting the HEIC to JPG tool card.

No software installs or server uploads required. Works with photos from iPhone, iPad, and any Apple device.
Yes. AnyToAny supports all major image-to-image conversions. Select the appropriate image tool card — JPG to PNG, PNG to JPG, WebP to JPG, PNG to WebP, or JPG to WebP — drag your files in, and download the converted images instantly. All conversions use the HTML5 Canvas API and run 100% locally in your browser.
Yes. Upload your .docx file, select your preferred target format, and our client-side Mammoth.js parser will instantly extract the text, headings, list markers, and formatting. It compiles it into clean Markdown text or wraps it into a downloadable PDF document completely in browser RAM — no server processing involved.
Click the PDF to Word tool card, upload your PDF file, and click Convert. Our PDF.js-powered converter renders each page at high resolution, extracts all text with precise positioning, and compiles a faithful Microsoft Word (.doc) document.

You can convert Excel sheets (.xlsx/.xls) to CSV tables, compile CSV raw lists into formatted Excel workbooks, or translate tabular CSV/Excel rows into structured JSON arrays for developer use — all running offline without any server uploads.
Select the Video Audio Extractor card for MP4/WebM files, or the Audio to WAV card for MP3, M4A, and OGG audio files. The browser's built-in Web Audio API decodes the audio channels locally into raw PCM buffers, which our WAV compiler wraps into a lossless, high-quality .wav file for download. No encoding software needed.
Yes. Select the Image to PDF tool, upload multiple JPG, PNG, or WebP images, and configure the page orientation. The jsPDF library will compile all your images into a single, well-formatted A4 PDF document that you can download instantly. Drag to reorder images before compiling.
Yes, 100% safe. Because the conversion code runs entirely locally in your browser using JavaScript, your files never cross the internet. You can even open this site, completely disconnect your internet connection, and the converter will still work perfectly — assuring absolute isolation and maximum data privacy for your sensitive documents.
Yes, AnyToAny Converter is fully responsive and works on smartphones and tablets running modern browsers (Chrome, Safari, Firefox, Edge). You can convert files directly from your phone's photo library or file manager. Note that very large files may be slower to process on devices with limited RAM.
There is no server-imposed file size limit since all processing occurs in your browser. However, the practical limit is determined by your device's available RAM. Modern browsers on desktop computers can comfortably handle files up to several hundred megabytes. For best performance with large video or high-resolution image files, we recommend using a desktop or laptop computer.
