The darkroom for your browser.
Pythonware is a small workshop of focused image tools — convert a format, crop to a shape, pull text off a screenshot, lift a colour palette. Every tool develops your image right here in the tab, so your pictures never leave your machine.
The toolbox
Pick a job, get it done
Each tool does one thing carefully — no sign-up, no watermark, no queue. Open it and start working.
Image Converter
Switch between PNG, JPG, WebP and BMP without losing quality.
open →Shape Cropper
Cut images into circles, stars, hearts, rhombus and rounded squares.
open →Image Resizer
Set exact pixel dimensions or scale by percentage, keeping the ratio.
open →Image Compressor
Shrink JPG and WebP file size with a quality slider you control.
open →Rotate & Flip
Turn an image in 90° steps or mirror it horizontally and vertically.
open →Image to Text (OCR)
Read printed text out of a photo or screenshot and copy it as plain text.
open →Background Remover
Lift a person out of their background and save a transparent PNG.
open →Colour Picker & Palette
Sample any pixel's colour and pull a dominant palette from a photo.
open →Image to Base64
Turn an image into a data URI you can paste straight into CSS or HTML.
open →Your files stay put
The tools read and edit your image inside the browser tab. Nothing is uploaded, so even sensitive screenshots stay on your machine.
No accounts, no limits
There's no login wall and no daily cap. Open a tool, drop in a file, and you're working in a couple of seconds.
Plain, fast pages
Each tool is a lightweight page that loads quickly on a phone or a slow connection, and keeps working once cached.
About these image tools
Pythonware started as a handful of scripts for fixing images the tedious way — converting a folder of screenshots, cropping a headshot into a circle, squeezing a photo under an upload limit. The site collects those jobs into small web tools that anyone can use without installing anything.
Because everything runs with the browser's own canvas and a couple of well-known open libraries, there's no server doing the work and no copy of your picture sitting in someone else's storage. That's better for your privacy and it's why the tools stay fast. If you have an idea for a tool that belongs here, the contact page is the place to send it.
