Best File Format for Uploads: Images, Documents, Audio, and Video

Choose the safest upload format for forms, school portals, job applications, social platforms, and email attachments.

The safest upload formats

For most uploads, JPG is safest for photos, PNG for screenshots, PDF for final documents, MP3 for audio, and MP4 for video.

Read the accepted file types

Always check the upload instructions. A technically better format is not useful if the form only accepts a short list of extensions.

Common first conversions

Convert HEIC or WebP to JPG, DOCX to PDF, WAV or M4A to MP3, and MOV to MP4 when a form rejects the original file.
