Affordable premium, offline-first software. Local-first; no subscription trap. Culltron Max and Ultra X27 (Ultra X27 generation). Affiliate disclosure.

What this covers

Flyers, menus and price lists need to stay on-brand and print cleanly. Studio Max is a layered design studio that does both on your own machine.

The Culltron tools for this job

Studio Max

A layered design studio for flyers, menus, social posts and brand material. It is an original app, not a clone of Canva or Adobe.

  • Text, shapes, lines, polygons and images as movable, resizable layers, each with its own opacity and blend mode.
  • 13 original templates and brand kits. Applying a kit saves its palette and font roles into the design.
  • Brand preflight that flags text and vector layers that drift from the saved palette or fonts.
  • Non-destructive masks (rectangle, ellipse and 3–64-point polygon) with feathering, invert, and add, subtract and intersect operations.
  • Non-destructive image adjustments (blur, greyscale, brightness, contrast, saturation, sepia, invert and hue rotation) and source cropping.
  • PNG and SVG export that renders the same way as the canvas.

Limits: Arbitrary pixel or colour-based selection and edge-refinement tools are not claimed. Brand preflight produces review findings, not automatic brand approval.

PDF Max

A local PDF workstation. Nothing is uploaded unless a separate connected workflow says so explicitly.

  • A viewer with page thumbnails, zoom, rotate, jump, keyboard navigation and text search.
  • Organise, rotate, delete, crop and extract exact page ranges. Merge files, turn images into a PDF, export pages to PNG and extract text.
  • Edit metadata and add watermarks and page numbers.
  • Inspect and fill AcroForm fields, author fields after review, and optionally flatten. Add bookmarks and page labels.
  • Local preflight checks for structure, accessibility and print, plus bounded OCR to create searchable copies.
  • AES-256 password encryption and authorised decryption, available when qpdf is installed. Each change writes a separate copy and a receipt.

Ultra X27: adds stamps, presets for watermarks and page numbers, appearance-only signature marks, metadata cleaning, three lossless optimisation profiles, batch merge/split/watermark/numbering, and document binders.

Limits: Production edits refuse dynamic XFA forms and PDFs that already carry signatures rather than silently invalidating them. Signature marks are visual and are not digital signatures.

Who it is for

How it works

  1. Each Max app is a separate desktop product built on Culltron's shared, hardened platform.
  2. Files and records stay in a local folder on your machine, and the core tools work offline.
  3. A signed licence lease unlocks the paid edition. Ultra X27 adds advanced features that the server enforces.
  4. When you change a file, the app writes a new copy, often with a checksum receipt, instead of silently overwriting your original.

Frequently asked questions

Does it come with templates?

Yes, 13 original templates.

Can it keep me on-brand?

Yes. Brand kits save the palette and font roles into the design, and preflight flags anything that drifts.

What export formats are supported?

PNG and SVG, both rendered the same way as the canvas.

Is it a Canva clone?

No. Studio Max is an original Culltron editor.
