why is every image on 卐witter in .jfif format

I just change the extension to .png and save it, it works but is rather annoying. Also add .jfif and .jpg-large to the list of stupid bullshit nobody likes.

.jfif be like.

It does make a difference! Some sites don't support certain file types, e.g. .webp, avif, jfif... etc.

AI deep scan Verdict: this is not a legit documentary photo based on the uploaded file and web provenance. Best read: a reposted, low-quality meme/AI-or-Photoshop composite, not evidence of a real meeting. File / metadata scan The uploaded image is a JPEG, 1536×875, about 126 KB, RGB/sRGB. It has: No EXIF camera data. No camera model, lens, timestamp, GPS, shutter, ISO, or original capture info. No XMP / C2PA / Content Credentials provenance. No visible generator/software tags like Photoshop, Midjourney, DALL-E, Stable Diffusion, etc. Only basic JFIF ICC color profile data. That means this is not an original camera file. It has almost certainly been downloaded/re-encoded/screenshot/cropped through a platform. Metadata absence alone does not prove fake, but it kills any claim that this file itself proves authenticity. Visual forensic tells The big red flags are visual, not metadata: The pale red-coated figures have melted facial anatomy, especially the left profile: eye/nose/mouth structure does not resolve like a real face or even clean makeup. Their clothing trim and silhouettes are inconsistent and smeared, more like AI/composite artifacting than real ceremonial costume detail. The whole image is aggressively blurred, but not in a clean optical way. It looks like blur is being used to hide generation/compositing seams. No clear ground contact, shadows, footwear, hands, or press-context details are visible. A real event photo of something this bizarre would almost certainly have multiple angles, press captions, or video coverage. Web-origin trail The strongest public match I found is not a news/press source. It appears in a gaming/fandom meme context: a Reddit post in r/ElderScrolls titled “White-Gold Concordat. Circa 4E 175” with a Humour flair. That is a fantasy-game joke framing, not a real-world event claim. A later r/aliens thread discusses the same image as a fake/edited image being passed around, with one commenter specifically pointing back to the Elder Scrolls humor post and interpreting the pale red-coated figures as fantasy “Thalmor / High Elf”-style figures rather than real beings. There is also current public chatter around surreal AI videos/images involving this same public figure being placed into bizarre global/fantasy scenes; one recent article describes an AI-generated “Thank You, President Trump” music video that places him in multiple impossible settings. That does not prove this exact frame came from that video, but it fits the same ecosystem of viral AI political imagery. Confidence rating Fake / manipulated: 90–95% confidence. Exact method: uncertain. It could be fully AI-generated, AI-overpainted onto a real photo, or a Photoshop-style composite blurred to look like leaked footage. What I cannot prove from this copy alone: the original creator, the first upload, or whether a real base photo was used underneath. For that, you’d need the original source file or the earliest post/link before compression stripped everything useful. But as-is? Yeah, this is almost certainly slop/meme bait, not a leaked legitimate photo.

UIDAI claims to accept JPG/PNG/PDF. But... ❌ 209161 byte "JPEG image data, JFIF standard 1.01, resolution (DPI), density 300x300, segment length 16, progressive, precision 8, 1203x1072, components 3" ✅899848 byte "PNG image data, 1203 x 1072, 8-bit/color RGB, non-interlaced"

If you couldn't hate jfif. files even more, can't even drag images from xitter to desktop.

DISCORDでは未公開の1100/1500用スキン「SAKU美SAKU楽」を公開します(^^)/　キハ４０のカラーリングなので本当は中間車はありませんが(^_^;) なお拡張子がjfifに変わってしまうのでjpgに変更してお使いください。 #走ル列車 #RUNNINGTRAIN

[ Looks at *.jfif ] ¿who the fk are you?!! oh... *.jpg w lipsick, okay... [screams at *.webp in Spanish ^&*&ñó¿^#%]

Возможно проблема не в большом размере, а в ебучем .jfif формате

あぁこれもjfifになっちゃうのか

Verdict: I don’t see strong evidence that this is fully AI-generated. It looks more like a real convention photo that has been heavily phone-processed or beauty-filtered. What I found: Metadata: the JPEG has no camera EXIF data, no visible AI generator tag, and no C2PA/Content Credentials. It only has basic JFIF/ICC color profile data. That usually means it was exported, screenshotted, reposted, edited, or compressed somewhere. Visual consistency: the Halo booth, background crowd, armor, lighting, shadows, and perspective all look coherent. The “117” and “UNSC” text are readable and not the usual AI-gibberish mess. Human/armor details: no obvious melted fingers, warped limbs, impossible armor joins, or duplicated crowd faces jump out. Suspicious/edited-looking parts: the face is extremely smoothed/polished, with very “beauty filter” skin texture and eyes/lashes. That could be normal makeup phone portrait processing, but it could also involve AI retouching or face enhancement. So my read is: Probably a real photo with possible AI/beauty-filter enhancement, not an obvious pure AI image. I’d put the likely AI involvement, if any, in the “retouching / smoothing / enhancement” category rather than “generated from scratch.”

XMP can go along with anything as a sidecar file or can be embedded directly in TIFF/PDF/Exif(i.e. non-JFIF JPEGs). I think the ISO 19445 standard XMP fields would cover everything you want w/r/t paper and printing conditions :)

今天发现异环启动器更新要865.93MB，觉得不对劲，用WizTree扫到一个799MB的美术资产，看到JFIF怀疑是JPEG序列，用RccExtended真拿到了300张安魂曲（角色）的2K 图片🥰 所以异环启动器运行时内存里有799M是安魂曲吗，做成视频是不是启动器更新体积、存储空间、运行内存都会更小🤔

＜拡張子の表示方法 ※画像参照＞ renコマンドを使って「JFIF」→「PNG」に変更されていましたが、もし拡張子が非表示になっている場合は、「ファイル名拡張子」をONにすることで表示されるようになり、名前の変更から拡張子を変更できるようになります✨ #んなたん見て見て

The .jfif file on the screen.

Просто он пока толком и не поддерживается бытовыми программами и используется в основном в вёрстке сайтов. Причём так часто, что когда вы скачиваете .jpg/.png есть большой шанс что это сайт вам его сконвертировал из .webp А вот .jfif реально тварина конченная

Due cose di oggi: - Sia maledetto il formato jfif - Si vede che sono a casa perchè il temporale che sembrava volesse scendere dal trevigiano ha invece preso la strada del padovano
