This is a quick-reference for video and image specs: the sizes, frame rates, bitrates, formats and aspect ratios you need to deliver clean footage and stills across platforms. It is built for videographers and short-form creators who want the right numbers in one place instead of hunting through ten help docs. Every section ends with a single best-format recommendation so you can move fast.
The container is the file wrapper (MP4, MOV, WebM); the codec is how the picture is compressed inside it (H.264, H.265, VP9, AV1). For delivery you almost always want MP4 with H.264, because it plays everywhere.
Container / codecWhat it isBest for MP4 / H.264Universal, AAC audio, baseline supportUniversal delivery and uploads MP4 / H.265 (HEVC)About 50% smaller files, limited browser playback4K, HDR and Apple devices MOVApple QuickTime wrapperEditing; convert to MP4 for delivery WebM / VP9About half the bitrate of H.264Web playback (Chrome, Firefox, Edge, Safari 14+) WebM / AV1About 30% smaller than VP9, slow to encodeWeb playback where encode time is not a concerniPhone note: iPhones record MOV with HEVC by default. To record the widely compatible H.264 MP4 instead, set Settings > Camera > Formats to "Most Compatible". The most common fix people need is converting MOV/HEVC to MP4/H.264 so footage plays and uploads anywhere.
Best format: deliver MP4 with H.264 video and AAC audio.
Vertical 9:16 at 1080x1920 is the safe default for short-form across every platform. The tables below give the practical targets. Where a platform does not publish exact upload bitrates, the number shown is a reliable working value, not an official figure.
Max file size is around 4GB. Best format: 1080x1920 9:16 under 90 seconds for Reels.
Mobile uploads cap around 287.6MB. Best format: 1080x1920 MP4 with H.264.
Best format: 1080x1920 MP4 with H.264.
These are YouTube's recommended SDR upload bitrates. Container is MP4 with H.264, audio AAC-LC stereo at 384kbps, color BT.709.

Max file size is around 4GB. Facebook merged feed video into Reels in June 2025. Best format: 1080x1920 9:16 MP4 with H.264.
Standard file size caps around 512MB. Best format: 1280x720 MP4 under 2:20.
Best format: 1920x1080 or 1080x1350 MP4 with H.264. If your clip is a MOV that LinkedIn rejects, convert it to MP4 first.
Pick the format by job: JPG for photos, PNG when you need transparency or crisp graphics, WebP as the modern web default, AVIF for hero images, and convert HEIC before you share it.
FormatWhat it isBest for JPGUniversal lossy photo formatPhotographs and general sharing PNGLossless, supports transparency (alpha)Logos, screenshots, graphics with transparency WebPAbout 25-35% smaller than JPEG, about 96% browser supportThe web default for photos and graphics AVIFAbout 20-30% smaller than WebP, about 95% support, slow to encodeHero images with a fallback HEICiPhone default, about half the size of JPEG, poor web support (Safari 17+ only)On-device storage; convert before sharingWeb optimization: WebP is the practical default in 2026. For hero images, serve AVIF inside a <picture> element with an AVIF to WebP to JPEG fallback chain. iPhone shoots HEIC by default (Settings > Camera > Formats), so convert HEIC to JPG when you need a file that opens everywhere.
Common conversions: HEIC to JPG for compatibility, PNG/JPG to WebP for web performance, PNG to JPG for a smaller file when you do not need transparency. You can resize, crop and re-export stills in the image editor.
Best format: WebP for the web; JPG when you need maximum compatibility.
All values in pixels. Match these and your profile art, covers and posts stay sharp instead of getting recompressed into mush.
