What's new on Cromagnon, day by day.

Cromagnon has a new look inspired by the first toolmakers: parchment pages, cave-dark headers, bone and red ochre, and old-book headings.

The studios page opens with a catalogue of every studio, each with its own museum-object picture, followed by a full write-up of each one. Open →

The pricing page now explains why everything is free, compares Cromagnon with typical online tools and paid suites, and answers more questions. Open →

New pictures at the top of the tools, pricing, blog, FAQ, contact, changelog, status, extension and privacy pages, and tighter spacing on the home page.

The quick tools and every studio share the new look; work areas stay plain so pages, cells and photos are easy to read.

Every studio now has a complete guide underneath it: features, step-by-step tutorials, tips and tricks, shortcuts, common fixes and answers to frequent questions.

Keyboard shortcut cards no longer squeeze their text, and questions open with a clear + marker.

The guide under Image Studio is readable in the Dark and Black themes.

Sharing a Cromagnon link in a chat or on social media now shows a picture and the right title for that page.

New guides for the file viewer, log viewer, CSV cleaner, duplicate remover, column analyzer, Word text extractor, JSON ↔ CSV, cURL builder and robots.txt generator. Open →

The image compressor, converter and resizer have their own pages again, each opening Image Studio on the right tool.

The studio tiles on the home page show each studio's museum-object picture, and the home page has a new "Made by humans" band and the latest updates.

A new page for links that lead nowhere: "This cave is empty", with a tool search, every studio and the popular tools.

Find Cromagnon on Discord, Telegram, X, Facebook, YouTube and LinkedIn: links in the footer and on the contact page. Open →

The guides page now lists only real articles.

Factur-X / ZUGFeRD invoices now pass the official PDF/A-3 check (veraPDF) and the EN 16931 business rules, for invoices, credit notes and debit notes, in any script.

The hidden text that makes scans searchable now uses the PDF standard's invisible-text mode, which archive (PDF/A) checkers accept.

Select people parts with on-device AI: face skin, body skin, hair, eyebrows, eye whites, iris, lips, teeth and clothes — for everyone in the photo, even in groups.

Landscape selections: sky, water, architecture, vegetation, mountains, natural ground and artificial ground, in any combination.

Mask presets such as Whiten teeth, Brighten eyes, Smooth skin, Deepen sky and Lush vegetation, and save your own.

Combine masks: add, subtract or intersect one selection with another.

Portrait background blur: keeps the people or subject sharp and blurs everything behind them, without a halo.

Export and batch export now render in the background, so the page stays responsive, with progress for each photo.

The AI Sky selection works again.

Batch: do the same job to up to 200 PDFs at once — rotate, flatten forms, page numbers, headers and footers, Bates numbers that continue from file to file, watermarks, remove metadata, split into pages, or protect with a password — and download one ZIP. Files that fail are listed with the reason, and the rest carry on.

Every PDF feature is now checked against a library of 27 tricky files: encrypted, damaged, cut-off, very old, rotated, form-filled, bookmarked, right-to-left and 300-page PDFs.

Batch jobs open files that only restrict editing, even when you typed a password meant for other files.

Quote & cite: your highlights become quotes with page numbers, saved to a source in Citation Studio or copied with their in-text citations.

Highlights → cards: every highlight, made here or already in the PDF, becomes a fill-in-the-blank flashcard in Study Studio.

Teachers can give class decks a due date, download the class dashboard as a CSV file, and see a weak-topic report: the topics and cards the class finds hardest.

Story mode progress — XP, stars, boss rounds, badges and your streak — now follows your account to every device.

Cards can show their source (a book and page, a reference or a link), and cards made from PDFs, slides and quotes fill it in for you.

Flashcards: each slide's title becomes a question and its points the answer, in Study Studio.

Turn your calculator, equation or calculus history into flashcards.

Photo → maths: take or choose a photo of printed maths, check what was read, then solve, calculate or graph it. Powers like x² are read too, and nothing is uploaded.

Open a CSV or Excel file in Statistics and Tests & fits and send any column of numbers to the right box; decimal commas, currencies and percentages are understood.

Statistics: open your table in Math Studio for descriptive statistics, t-tests, ANOVA and curve fits.

Four more styles: Nature, Science, APA 6th and MHRA — 18 in all.

Quotes are kept with their source, ready to copy with the citation and page, and quotes and sources can become flashcards.

Links from about 50 major news sites around the world now get the paper's proper name, and government and international pages (WHO, UN, GOV.UK and government sites everywhere) get the right body as the author.

Expenses: add what your business spends, or snap the receipt and let your device read the payee, date, total and tax. Receipt photos stay on your device.

Profit & loss on the dashboard: sales, expenses, profit and margin for any period, by invoice date or by money in and out, with tax on sales and on expenses side by side.

New tool pages: outlier finder, correlation matrix, frequency table and an Excel workbook merger.

The JavaScript minifier now really minifies, the cron parser shows the next run times, and the line sorter and time zone converter were fixed.

27 more looks — 45 in all.

Series: does it converge? Ratio, root, comparison and alternating series tests, with the sum.

Memory hooks on cards, 10 note templates, cards from a web page, and Match with friends for 2–4 players on one device.

A client portal link with all of a client's documents, branches, and street, postcode and city fields for e-invoices.

A status page shows whether sign-in, sync and storage are working. Open →

Factur-X / ZUGFeRD: download any invoice, credit note or debit note as a PDF with the e-invoice data inside — the format used in France and Germany and accepted across the EU.

Debit notes: add an extra charge to an invoice you've already sent, in any of the 26 document languages and as a UBL e-invoice.

A new name: Cromagnon. Humans have always been toolmakers; these are free tools for the modern one. Same studios, same privacy, and everything you saved in your browser comes with you.

This changelog: every Cromagnon update since day one, filterable by studio and by new / improved / fixed, with an RSS feed. Open →

Finished mail merge: upload a CSV or Excel list, insert fields, address blocks and greeting lines, add IF rules, preview every letter, check for errors, then download one merged Word file or PDF, a file per person, or label sheets in Avery sizes.

Compare two files, join tables, add a formula column, validate columns, find near-duplicates, see a data-quality report and build two-level pivot tables. Big files open without freezing the page.
