Need the text out of a screenshot? Don't retype it. Image to Text pulls it out with OCR, free, no signup, and the image stays in your browser. Works on scanned pages too. https://t.co/QhoYMWrehG #OCR #productivity

Why does your iPhone save HEIC? Apple says it keeps JPEG-level quality in less space, about 2x compression on average (WWDC17). Need JPEGs? Settings > Camera > Formats > Most Compatible. https://t.co/JkqG3U1TOj https://t.co/h4N3oR0PM7 #HEIC #iPhone

A 46 KB PDF with no macros or JavaScript passed the scanners. Just opening it sent the browser to a phishing page via OpenAction, a standard PDF feature. If a PDF opens a tab by itself, close it. Don't log in. https://t.co/efrFLULJKL #infosec #PDF

Sending data to someone: CSV or XLSX? CSV opens anywhere but drops formatting, formulas and extra sheets, and leading zeros can vanish on open. XLSX keeps it all but needs a spreadsheet app. Our pick: CSV for data, XLSX for reports. Yours? #CSV #Excel

The AV2 video spec is final. AOMedia says it matches AV1 quality with about 30% better compression. Don't expect it on your phone yet: software comes first, hardware later. Long term: same picture, less data. https://t.co/81N7aA2wjd #AV2 #video

FLAC is lossless: decode it and you get the exact original audio back, bit for bit. MP3 throws data away to save space. Keep FLAC as your master, make MP3 copies for your phone. https://t.co/4KyqYZnT03 https://t.co/dzmElmiqAo #FLAC #audio

Microsoft: QR phishing rose 146% in Q1 2026, mostly hidden in PDF attachments. By June it fell back to 8.3M a month. Rule: never scan a QR code from a PDF you didn't expect. https://t.co/YsBUIQLm1R https://t.co/YUfvgE7OnV #phishing #QRcode

@jyzg @sanpsonfox Fair point, thanks. AVIF's edge really shows at low bitrates. At the quality most sites actually ship and above, JPEG XL keeps more detail, and it can losslessly recompress existing JPEGs too.

Before you hand a document to an AI tool: PDF or Markdown? PDF keeps the look. Markdown keeps the structure, so headings, lists and tables reach the model as clean text. For AI, we lean Markdown. What do you feed yours? #AI #Markdown

"HEIF Heist": researchers at Hacktron say crafted HEIC/AVIF uploads could exploit old libheif versions on servers, with RCE at big platforms. Fix: libheif 1.23.2+. Image files are attack surface too. https://t.co/ytgprBbKu4 #infosec #HEIC

[Convertlo @Learning4_AI]

Hot take: HEIC isn't a bad format. It's a support problem. Great files, but half the apps and upload forms still reject them, even some AI chat apps. Should Apple default to JPEG, or should software catch up? #HEIC #iPhone

AVIF keeps spreading. Amazon switched some product images, including Kindle covers, to .avif in mid-September. Calibre 9.16 now reads AVIF images too. When the biggest store moves, tools follow. https://t.co/ZYDn5WgaLV #AVIF #ebooks

The format war is back. AVIF often wins at small, low-quality sizes. JPEG XL shines for high quality, lossless, and repacking old JPEGs. Our take: the web will use both. Which one are you shipping? #JPEGXL #AVIF

JPEG XL is back in Chrome. Chrome 155 now decodes .jxl by default, using a decoder written in Rust. Google says 30-50% better compression than JPEG, plus lossless and HDR. A big turnaround. https://t.co/eyjP19R8gD #JPEGXL #Chrome

Form to sign? Skip the print-sign-scan loop. Draw, type, or use a photo of your signature, then add the date and initials right on the PDF.

Guests keep asking for the WiFi password? A WiFi QR code holds the network name, password and security type. Phone cameras scan it and offer to join.

Tip: test-scan before you print. Free, no signup, stays in your browser.

Phone JPGs are huge: high quality plus EXIF. Compress around 75 for email and the web. The photo still looks sharp. Keep PNG for screenshots and text.
