Overview
sakuttoAI is a free suite of around 90 online tools for the small, repetitive tasks that interrupt real work. Instead of searching for a different one-off converter every time, you can compress a PDF, convert a HEIC photo, compare two versions of a text or turn a CSV into an Excel file in one place. The site is available in English and Japanese.
Key Features
- PDF tools: compress, merge, split and rotate PDFs, add page numbers, headers, footers and watermarks, sign and stamp, set or remove passwords, and convert PDFs to JPG, PNG, WebP, text or Markdown.
- Image tools: convert HEIC, WebP, PNG, JPG and SVG, resize, crop, rotate and flip, compress, blur or mosaic parts of a photo, remove EXIF metadata, and remove backgrounds.
- AI tools: upscale images to 2x or 4x, make thumbnails, read text from images (OCR) and turn receipts into CSV.
- Text and data tools: character counter, text diff checker, JSON formatter and validator, line sorter, CSV to Excel and Excel to CSV, CSV merge and compare, and Markdown converters for Word, Excel, PowerPoint, HTML and URLs.
- Everyday utilities: QR code generator and reader, barcode reader, password generator, time zone converter and world clock.
Privacy
Most tools process files right in your browser, so your files are not uploaded and there is nothing to install. Some AI-powered tools need server processing.
Use Cases
- Shrinking a PDF before attaching it to an email or uploading it to a form.
- Converting iPhone HEIC photos to JPG for a website or a document.
- Checking what changed between two drafts of a contract or an article.
- Turning a CSV export into an Excel file for a colleague.
- Converting a Word or PowerPoint file to Markdown for notes or an AI prompt.
Getting Started
Open https://sakutto.ai/en and pick a tool from the list, or start from the type of file you have. Text tools such as the character counter and QR code generator work without an account. File tools such as PDF and image compression need a free account, and signing up takes only an email (no password).
Pricing & Plans
- Free: all tools, with limits. A free account can run up to 3 tasks per day, and the first run of a tool you have not used before does not count toward the limit.
- Pro: no daily limits and an ad-free experience. AI features processed on the server use credits.
