What we build

Services for every stage of your product

From the first prototype to a platform at scale: web and mobile apps, SaaS products, business systems and automation.

Web development

Modern, responsive websites and web applications built with React, Next.js and Laravel.

Mobile app development

Cross-platform apps for iOS and Android, built with Flutter and React Native.

UI/UX design

User-centred design that makes products clear, usable and consistent.

CRM & ERP solutions

Custom business systems tailored to how your team actually operates.

SaaS product development

End-to-end development of scalable software-as-a-service products.

WhatsApp automation & bots

Automated messaging and chatbots on the WhatsApp Business platform.

Free online tools

Handle PDF, image and spreadsheet files in seconds

Merge, compress, convert and clean files in your browser. Free, no sign-up, and your files are deleted as soon as you are done.

PDF tools

Merge, split, compress, protect, number, watermark and convert PDF files.

Image tools

Convert, compress, resize, crop and watermark images, and remove location data from photos.

Spreadsheet tools

Convert, clean, merge, split, profile and compare Excel, OpenDocument, CSV and JSON files.

Most used

Combine several PDFs into one, in the order given, with a bookmark for each file.

Shrink a PDF: downsample and recompress oversized images, then rewrite with compressed object streams. Never returns a bigger file than you gave it.

Make images smaller for the web or email: smarter encoding, optional resizing, or a target size in KB. Never bigger than the original.

Remove location (GPS), camera, date and software details before sharing. JPEG, PNG and WebP keep their exact pixels.

Convert between Excel (.xlsx, .xls, .xlsb), OpenDocument, CSV, TSV and JSON, keeping numbers, dates and codes such as 00123 exactly as they are.

Tidy a spreadsheet in one pass: trim stray and invisible spaces, fix numbers stored as text, drop empty rows and columns, remove duplicates, tidy column names.

Split a PDF into several files: by page ranges, every N pages, or one file per page.

Convert between JPG, PNG, WebP, AVIF, GIF, TIFF and BMP, keeping animation and colour profiles where the format allows.

How we work

A clear process, from first call to launch

Transparent communication and regular updates throughout, with a plan you agree before work starts.

  1. Discovery and planning

    We learn your goals, users and constraints, then agree scope, milestones and a delivery plan.

  2. Design and prototyping

    Wireframes and clickable prototypes settle the experience before code is written.

  3. Development and testing

    Short iterations with regular demos, automated tests and reviewed code.

  4. Launch and support

    We deploy, monitor and hand over documentation, then stay on for fixes and improvements.
