Important changes, architecture choices and known limitations are documented here.
Public pages gain depth around the five tools, free access, privacy and contact. The footer is more compact, direct details are revealed on demand, and SEO/GEO metadata plus agent and human information files are aligned.
The PDF page is fully redesigned around composition, file order and result review. The existing merge engine remains unchanged while Koperateur becomes the main ecosystem highlight for this workflow.
Read integrates Tesseract.js and six self-hosted language models for local OCR of images and scanned PDF pages. The layout is also tightened to reduce unused space and let the H1 use the available width naturally.
Verify gains an Inspection Desk with selected preview, structured report, local PNG/JPEG/WebP inspection, local SHA-256 fingerprint and explicitly cautious conclusions.
changelog.v493_body
Clean gets a dedicated interface with a larger dropzone, thumbnails, detected/not-reintroduced summaries, MariaDB-confirmed statistics and a stronger AfterAlgorithm complementary-inspection block.
Clean and Prism align their statistics with MariaDB using idempotent counting for each successful file. Clean gains thumbnails and per-image states, Prism removes workspace overlaps, and the five tools adopt a clearer layout with versioned assets to avoid stale persistent caches.
WebPion now focuses on Prism, Clean, Verify, Read and PDF. Home can pass its batch to Prism, Clean makes statistics reliable, Verify separates readable evidence from missing signals, Read focuses on extraction, and PDF can now assemble PDFs and images in a chosen order.
Home is more compact, decorative format icons are removed, side columns become useful cards, and the main desktop heading is easier to read. The V4.8.1 engine, large batches, counters and WEBPION.txt remain unchanged. Batch and thumbnail transfer to Prism is deferred to the next phase.
Home now has a larger drop area, stronger light and dark theme contrast, clearer hover states, direct access to Prism and a Reset limited to temporary Home data. Every image ZIP now includes the same WEBPION.txt in French, English, Spanish, German, Italian and Portuguese.
The Home engine is isolated and rebuilt to convert PNG, JPG and WEBP locally in both directions, consolidate PDFs and process large batches without an application-level file count limit. Confirmed statistics are written idempotently to the existing historical tables.
Files transferred from Home remain available until processing completes. Prism waits for batch statistics confirmation before cleanup and Home reloads the public database snapshot.
Prism limits active thumbnails, no longer rebuilds the full grid for every file, and isolates preview failures from processing. A real 174 PNG + 5 PDF browser smoke is covered.
Prism now accepts large batches immediately without waiting for the network, then aggregates statistics after processing. Public counters no longer depend on encrypted detail storage, 179/500/4,000-file batches are covered by tests, and HSTS now includes the preload directive.
Verify now accepts multiple images with thumbnails and readable metadata. Clean counts each successfully processed file through signed idempotent batches. The Prism menu, contrast, API security and multilingual SEO are improved.
The Privacy dock can now be acknowledged with “Got it” without deleting functional local data. The Koperateur / Kachouri ecosystem is integrated as a native light/dark component across Home, Prism, discovery pages and tools, with context-specific copy.
The Privacy module becomes a floating dock independent from the footer, readable in light and dark themes, responsive, with no change to engines or drag-and-drop workflows.
Expanded legal pages, clarified publisher and governance, added Privacy and local-storage inventory, reorganized footer and explicit AI governance without changing engines or drag-and-drop workflows.
Public pages redesigned, free access made explicit, Support and commercial-conditions pages added, contact messages and detailed GPTO statistics encrypted at rest, with SEO, GEO and agent-readable information completed.
W signatures and local SVG icons added without changing tool behavior, hardened multilingual JPEG Open Graph cards, consistent canonical URLs, plus stronger SEO and security headers.
Site-wide typography pass: no terminal period in H1, H2 or H3, less oversized hero headings, cleaner wrapping and a restrained WebPion accent, shipped through a versioned CSS asset to avoid stale caches.
A new mobile-first guidance layer on every tool, larger work areas, hardened GPTO with private FTP tokens, richer analytics and local multilingual social cards.
Consistent drag and drop, adaptive tool journeys, contextual recommendations and the full footer everywhere.
New MariaDB schema, persistent counters, analytics GPTO, need-based router, dedicated Clean/PDF/Prepare pages and a repaired tool shell.
The blocking right drawer is removed, Read, Verify and Remove actions move onto file cards, local transfer is restored and the 4.5.4 runtime is isolated from old cache.
Output profiles, format cards, adjustments, variants, watermarking and automatic download are brought together in the Studio.
Stable local file copies, clearer Firefox diagnostics, runtime isolation from old caches, readable output metrics and a mobile-first Studio.
Integration of the new W and Zero Knowledge lock, harmonized favicons and PWA icons, darker matte theme, compact statistics and homepage layout aligned with the validated mockup.
Abort-tolerant binary reads, Object URL first decoding, sequential processing, visible progress, and refined statistics and Zero-Knowledge presentation.
Prism rebuilt on a neutral page, actions visible without scrolling, type-aware previews, collapsed advanced options, multi-strategy image decoding and preservation of successful outputs.
Removed the fixed 20-file cap, added a progressive queue, an HTML/Canvas/Blob image baseline, lazy thumbnails, isolated errors and export of successful results.
Stronger image decoding, local export fallback, detailed per-file errors, Add-Configure-Process-Download guidance, a visible processing action near the top, a simplified language selector and a cleaned home W.
New per-file batch routing, previews, individual selection, isolated errors, reliable ZIP export, the new W on the home page and a refined GPTO interface.
Usage-oriented navigation, new explanatory pages, responsive Prism interface, stronger translations and local GPTO administration for Contact.
New branding, configuration moved under /config, SQL documentation, Prism handoff fix and improved portability.
Prism becomes the core, tool names are simplified, runtime CDN dependencies are removed and historical statistics are preserved.
Several functions are combined in one interface.
PDF processing joins the original converter.
Local image-format conversion in an experimental interface.
