Simple tools for everyday work

FormatKit is a lightweight online toolkit for working with images, text and structured data. It is designed to make small, common format tasks quick and pleasant.

Fast, free and focused

Every tool has one clear job. There is no account to create, no software to install and no complicated workflow to learn.

Browser first

Processing happens locally in your browser. That keeps the experience fast while helping your files remain private.

What you can work with

Use still JPG, PNG and WEBP images, plain text, JSON, CSV and Markdown. Images are limited to 40 MB, 40 megapixels and 16,000 pixels per side. Text file imports support UTF-8 files up to 5 MB. Animated images and unsupported formats are rejected explicitly.

Browser support

Use a current desktop or mobile browser with Canvas, image decoding and Unicode text segmentation support. Available memory and image encoders vary by device; a smaller image or another output format can help if processing fails.
