How to Convert HEIC to JPG

HEIC is the default photo format on iPhone and iPad. It saves space but often refuses to open on Windows, older Android phones and many websites. Converting HEIC to JPG makes your photos universally compatible.

  1. 1Open the Hungoo converter on the home page.
  2. 2Drag your .heic photo into the drop zone (or tap to browse).
  3. 3Choose “JPG Image” from the Convert To dropdown.
  4. 4Click Convert, then press Download File.
Pro tip: JPG is best for photos you want to share. Choose PNG instead if you need a lossless copy.

How to Convert WebP to PNG

WebP is a modern Google image format used across the web for its small size. Because many editors and older apps cannot open it, converting WebP to PNG keeps full quality and transparency while making the image openable everywhere.

  1. 1Drop your .webp file into the Hungoo converter.
  2. 2Select “PNG Image” to preserve transparency.
  3. 3Click Convert and wait for the progress bar to finish.
  4. 4Download your ready-to-use PNG.
Pro tip: Pick JPG instead of PNG if the image is a photo and you want the smallest file size.

How to Convert PNG to JPG

PNG files are lossless and great for graphics, but they can be large. Converting PNG to JPG dramatically reduces file size — perfect for email attachments, uploads and websites.

  1. 1Add your .png file to the converter.
  2. 2Choose “JPG Image” from the dropdown.
  3. 3Hungoo automatically fills transparent areas with white to avoid black boxes.
  4. 4Convert and download your compressed JPG.
Pro tip: JPG does not support transparency. Keep PNG if you need a transparent background.

How to Convert MP4 to MP3

Want just the audio from a video? Converting MP4 to MP3 extracts the sound so you can listen to music, podcasts or lectures without the video. Hungoo does this in your browser using FFmpeg technology — no upload required.

  1. 1Drop your .mp4 video into Hungoo.
  2. 2Select “MP3 Audio” as the output.
  3. 3The media engine loads once, then extracts the audio track.
  4. 4Download your MP3 file when it is ready.
Pro tip: You can also convert MOV to GIF or MP4 to WebM from the same dropdown.

How to Convert PDF to Word

Editing a PDF is painful — converting PDF to Word (DOCX) lets you change the text freely. Document conversion is rolling out on Hungoo; image and media conversions are already fully live and free.

  1. 1Open the Hungoo converter.
  2. 2Drop your .pdf file into the zone.
  3. 3Choose “Word (DOCX)” from the dropdown.
  4. 4Download the editable document.
Pro tip: For scanned PDFs, a text-based (not image-only) PDF gives the best conversion quality.
