Documents and resumes
Use PDF for resumes, portfolios, one-page documents, and files where layout should stay stable. Convert DOCX to PDF before uploading if the document is final.
Images and videos
Use JPG for broad image compatibility and MP4 for video. Convert WebP or PNG to JPG when a photo upload rejects the file, and MOV to MP4 when a video upload fails.
Professional check
Preview the uploaded file and confirm names, links, images, captions, and page order before posting or applying.
