Original engineering research, compression benchmarks, and typography guides published by our editorial and systems engineering team.
Fourteen ways to scan documents with your phone, from the free scanners built into iPhone and Android to Adobe Scan, Genius Scan and vFlat, compared on watermarks, OCR, multi-page PDFs and where your scans are stored.
Fifteen PDF editors compared on what they can really do: change existing text or only add text on top, fill and sign forms, rearrange pages, OCR scans, and redact properly. Free options, paid upgrades, and which upload your files.

A PDF stores drawing instructions, not a document. That one fact explains why text extraction fails on scans, why tables break, and why PDF to SVG gives you a picture rather than editable vectors.
A technical audit on cloud converter storage risks, multi-tenant server exposure, and how browser WebAssembly processes files locally.
How JPG, WebP and AVIF compress images, what the published size comparisons actually show, and how to serve all three so every browser gets the smallest file it can read.
A technical review of client-side audio trimming, gain adjustments, OfflineAudioContext rendering, and PCM buffer encoding.
A practical breakdown of typography reflow, e-reader accessibility, and why EPUB outperforms fixed PDF layouts on mobile screens.
